Product Page (http://www.goapr.com/products/tcu_upgrade_dl501_40t.html)

APR is pleased to present the ultimate transmission control unit (TCU) upgrade for the S6 and S7 DL501 DSG and S Tronic transmissions! APR’s TCU upgrade is conveniently flashed to the vehicle’s TCU through the OBD-II port with user definable options selectable at the time of install.

APR’s TCU upgrade goes beyond the overly simplistic norm of raising a few limiters, and offers a wide gamut of changes designed to enhance the driving experience especially when combined with APR’s performance engine software and hardware. With an in-depth knowledge of the transmission’s inner workings and control strategies, APR’s engineers have improved many aspects of the transmission from accelerative performance to daily drivability, while also incorporating new features including several typically reserved for higher-end Audi Quattro GmbH RS models.

Feature List

Faster acceleration through application specific optimized shift points.
Drive and Sport mode shift maps custom tailored to APR’s power upgrades.
User adjustable 3-step multi-launch control RPM limits.
User definable* max launch control RPM.
User definable* manual mode downshifts via the kick-down switch (on/off).
User definable* manual mode upshifts at max engine speed (on/off).
Launch control response enhanced for quicker launches.
Launch control limits raised from 200 to 3,000 launches.
Manual mode / TT mode paddle response time optimized.
Manual mode / TT mode shift time optimized.
Torque intervention limits raised while retaining critical protection routines.
Temperature management optimized.
Transmission coolant pump optimized during high temp scenarios.
Gear display enabled in Drive and Sport.
Downshift "lockout" disabled below previous gear's max RPM.

*APR’s DirectPort Programming suite allows the end user to tailor the TCU upgrade to their needs at the time of installation.

Drive (eco) and Sport Mode:

http://www.goapr.com/includes/img/icons/dsg-d.pnghttp://www.goapr.com/includes/img/icons/dsg-s.png

APR’s calibration experts found the factory drive and sport modes to be less than ideal when raising power above the factory limits. In drive mode, the transmission aggressively seeks sixth gear, earlier than necessary, leaving behind an anemic and lack luster experience for the driver. Likewise sport mode leaves a lot to be desired considering its seemingly exciting name. Under both modes, maximum shift points remain optimized for the factory power levels, which vary greatly to those produced using APR’s world-renowned catalog of performance hardware and software. As such, accelerative performance suffers due to non-optimized shift points.

To rectify this situation, APR’s engineers took a multi-step approach to custom tailoring the shift maps to sync harmoniously with APR’s performance upgrades and each platform’s gear-ratio configurations. While some may simply set wide-open-throttle, or WOT shift points to the vehicle’s max RPM limit, APR’s engineers chose shift points based on actual acceleration data. This result is gear dependent shift points typically below the engine’s max speed, but in doing so, the vehicle’s acceleration improves as axel torque is matched before and after shifts.

Under low-torque, low-rpm, part-throttle situations, both modes less aggressively seek the highest possible gear. Drive still has the benefit of economy, but stays within the power band more comfortably for a more enjoyable experience. Likewise sport mode has been optimized to provide a sporty feeling, worthy of its name. In both cases, the transmission seamlessly integrates with APR’s performance upgrades to provide an exciting driving experience.

Manual and Tiptronic Modes

http://www.goapr.com/includes/img/icons/dsg-m.png

APR’s user definable options allow the end user to configure how the transmission works while the gear selector is placed in manual mode.

The kick-down switch, which is responsible for an instant downshift, is enabled by default but can be disabled at the time of install. Likewise the auto upshift that occurs at the vehicle’s maximum engine speed can also be disabled at the time of install, allowing the engine to bounce off the limiter like a manual transmission. For safety’s stake, the auto first to second gearshift is still enabled.

The transmission does not lock out any manual downshifts so long as the shifting does not result in an engine RPM above the max shift point. In all situations, paddle delay is reduced, allowing for a more responsive shift to take place and furthermore, shift times have been optimized.

Shift Points

For use with the factory turbo:

Gear | Drive | Sport | Manual | Manual with Auto Upshift Off
First to Second Gear 6,275 RPM / 6,275 RPM / 6,550 RPM / 6,550 RPM
Second to Third Gear 6,250 RPM / 6,250 RPM / 6,550 RPM / Never
Third to Fourth Gear 5,900 RPM / 5,900 RPM / 6,550 RPM / Never
Fourth to Fifth Gear 5,425 RPM / 5,425 RPM / 6,550 RPM / Never
Fifth to Sixth Gear 5,375 RPM / 5,375 RPM / 6,550 RPM / Never
Sixth to Seventh Gear 5,225 RPM / 6,550 RPM / 6,550 RPM / Never

Launch Control

http://www.goapr.com/includes/img/icons/dsg-launch.png

APR’s 3-Step launch control is unlike anything else in the market. At the time of flashing, the user chooses a maximum launching RPM. When activating launch control, up to three launching RPM’s are available, allowing the end user to choose the best launching RPM based on the current conditions!

At 100% throttle with the kick-down switch engaged, the vehicle will select the highest launching RPM. At 100% throttle with the kick-down switch not engaged, a lower launching RPM is activated. Finally, at roughly 50% throttle the transmission chooses the lowest launching RPM. When properly dialed in, the user is left with incrementally higher launch points ideal for the street, track and sticky tires.

Utilization of launch control results in the transmission entering the maximum acceleration mode. During this mode, intervention between a shift is minimized, resulting in faster acceleration that keeps the driver planted to the back of his or her seat. The delay typically present after lifting the brake and beginning of the physical launch has been improved for a more immediate response.

Note: Both ASR and ESP must be fully off and the vehicle in Sport Mode to use Launch Control. This is accomplished by holding the traction control button for a length of time.

Adjustable Launch RPM Profiles

Max | Mid | Min
6,000 RPM / 5,000 RPM / 4,000 RPM
5,500 RPM / 4,500 RPM / 3,500 RPM
5,000 RPM / 4,000 RPM / 3,000 RPM
4,500 RPM / 3,750 RPM / 3,000 RPM
4,000 RPM / 3,500 RPM / 3,000 RPM
3,500 RPM / 3,250 RPM / 3,000 RPM
3,000 RPM / 3,000 RPM / 3,000 RPM

Recommendation: When using launch control, excessive wheel spin will not improve acceleration and may cause undesirable behavior. APR suggests using lower launch limits under low grip situations. Maximum launch RPM is only ideal with drag slicks / radials on a well-prepped drag strip.

S Tronic Temperature Management

http://www.goapr.com/includes/img/icons/dsg-temp.png

Temperature management is an important part of the DL501 transmission. While some may simply remove temperature protection routines all together, or mistakenly raise temperature protection torque limiters sky high and claim increased cooling performance due to zero transmission intervention, APR’s TCU upgrade only allows the maximum safe temperature levels before intervention. Under high stress scenarios, such as launch control, the transmission’s cooling pump runs at maximum speed until the desired transmission temperature is achieved.

Unlike the factory intervention routine, which allows for nearly no torque to be transmitted through the transmission at all after limits are crossed, APR’s over temp intervention allows for a limited amount of torque, enough so the vehicle can be safely driven off the track or pulled to the side of the road during intervention. In keeping the vehicle moving, airflow continues across the radiators, which in turn keeps coolant temps low and aids in removing heat from the factory DL501 oil coolers to restore full operation.

Torque Limits

http://www.goapr.com/includes/img/icons/dsg-torque.png

Various factory torque intervention limiters are raised to their maximum value to eliminate unintended torque intervention, across the rev range, during normal and spirited driving. However, important and critical limiters are kept in place or only slightly modified, such as those related to temperature protection, to prevent premature damage to the transmission in dangerous scenarios.

Note: DL501 transmission software is not required to meet APR’s advertised torque figures.

Gear Display Indicator

http://www.goapr.com/includes/img/icons/dsg-gear.png

In drive (eco) and sport mode, the vehicle’s multi function display will now indicate the currently selected gear rather than a generic D or S.

The APR Difference:

APR DirectPort Programming:
http://www.goapr.com/includes/img/icons/obdii.png
APR’s DirectPort Programming is now available for the Temic Tricore DL501 transmissions. Any APR Dealer in the world, connected to the Internet, has direct access to APR’s latest TCU upgrades for installation directly over the vehicle's OBD-II port. This completely eliminates the need to remove and open the TCU and can be uninstalled at any time!

APR TCU Upgrade Creation:
http://www.goapr.com/includes/img/icons/ecu.png
APR’s engineers have taken a direct and custom approach to calibrating the TCU. All too often others create a generic calibration that is forced across a wide range of different vehicles and transmission versions. Unfortunately this generic method of copy and paste tuning can result in some undesirable effects, such as slow up shifts and downshifts, torque interventions, stumbling, immobility and general incompatibility. In some extreme cases, damage to the transmission can occur. With many factory TCU variations available for the transmission, APR’s engineers have painstakingly ensured every TCU upgrade is created using the transmission’s original file to ensure the ultimate experience!

APR TCU Composer:
http://www.goapr.com/includes/img/icons/ecu_composer.png
APR’s proprietary TCU Composer is used for altering the transmission management system. With full access to every table, map and variable within every TCU, APR’s Calibration Engineers are not limited to the handful of pre-defined maps.

APR TCU Assembly:
http://www.goapr.com/includes/img/icons/ecu_assembly.png
APR’s Electrical Engineers have the ability to alter the code structure of the TCU. Through code-level changes, APR's Engineers are able to add future features to the TCU otherwise impossible through calibration changes alone.

The only difference right now are the shift maps. So, you can get the TCU upgrade for use with the stock turbos now, and then when you get the upgraded turbos and head in for a reflash, you can get the RS7 turbo shift maps at no additional charge.

Yes, a dealer flash of the TCU would remove the tune. Any APR dealer can flash your TCU back to stock before warranty service on the car. They can also re-install the tune afterwords.

Just called my local dealer and he said he's never done this and that I should just do Stage 1... tried to tell him I wanted to do both but not sure he understands.
I probably should wait a few days so he knows what's going on, huh? :)

We told them last week. Which dealer is it? Please PM me.

[edit] Clarification, we sent out the email for DSG software. Not ECU yet. If you have a new facelifted car, that's coming soon. We'll alert our dealers a few days before it's released to the public.

Hi Arin, not sure if you saw it or not, but does the ECU/TCU bundle pricing discount apply to the S6?

I'm sorry, we don't have any bundle pricing at the moment.

APR -- do you have any before/after 1/4 mile comparisons from the same day?

I'm sorry, I don't.

Wow this is great...

Question: Is the 200-launch count limit eliminated with this upgrade?

Yes, we were able to raise it to 3000 launches.

Arin

Will the 3 step launch be accessible by the doggle? As well as the lockdown and up shifts? On/off ...Or all this need to be decided at time of flash?

We can't do these via the dongle yet (not sure if that will change in the future either though as I don't know what's possible).

Right now you have to set these at the dealer. So, you choose the launch profile you want (min / mid / max) and if you want to change it, you have to get flashed again. The same applies to the up / down auto shifting.

Just to broaden the question -- what options will there be available via the dongle/app for this upgrade?

Unfortunately the same answer here of I don't know. I honestly can't say what will be possible, or what we'll end up doing so I rather not lead anyone to believe we'll do anything with it in the future.

Another question - are the default settings (prior to any user customization) based on APR's testing of the best "set it and forget it" settings? I can't see myself screwing around with it beyond the original configuration.

Auto kickdown off and Auto upshift off are both checkboxes during the install. It's not a preference of ours at all as it totally depends on the end user. I like it one way but others like it another way so it's 100% up to you.

For launch control, it's just a drop down menu. You choose what you want. I'd probably go somewhere like 5000 max but end up using the midway 4000 launching profile most of the time, but that's just me.

MYAUDIS7

08-26-2015, 02:05 PM

So stage III only has the max rpm to 7200?

Arin@APR

08-26-2015, 02:34 PM

So stage III only has the max rpm to 7200?

I don't have the exact shift point figures yet (for drive and sport) but it's higher than the S6/S7 stock turbo. What may not be entirely obvious is that a higher RPM doesn't mean faster times. You essentially want to keep axle torque as high as possible. If that means shifting earlier in the RPM band, then your acceleration time will increase as lateral G forces should be higher. So, in the example of the S6/7 turbo, we're shifting in the mid the low 5000 range on the taller gears.

Lol well those are very sexy dyno results but those are for the RS7 turbos! I was hoping for some dyno results from the TCU flash. Since the ad says it is 'tailored for APR's power upgrades' (tune?) I would imagine there is at least a 3-5% difference in HP/TQ?

Question: What happens to the launch control "count" when you flash from the APR software back to stock again? Is the same count retained? If so, wouldn't that raise a red flag when you're above 200 at some point?

There isn't a difference in output with the DSG flash. The only time there would be is if peak power is beyond where the factory transmission allows the vehicle to rev. On this platform, that isn't the case, but it is with the RS7 turbo upgrades.

Someone explain this to me in terms my 9 year old would understand...for optimal performance, why would I want to disable the auto kickdown, particularly when driving in dynamic mode? I've been assuming that Audi would have configured that setting for best performance.

This is completely a user preference. While in manual mode some people do not like the fact the transmission will downshift a gear if you smash the throttle and accidently press the kickdown switch. So, we give you the option to turn that feature off. If you like it (I happen to like it), you can keep it enabled. In both cases the transmission will still downshift at very low RPM to prevent the engine from stalling out.

Question: What happens to the launch control "count" when you flash from the APR software back to stock again? Is the same count retained? If so, wouldn't that raise a red flag when you're above 200 at some point?

We don't alter the value so it stays where it was.

Yup! Got it!

It doesn't increase output as we're able to get around the torque limiters on our ECU software alone (some require a TCU upgrade) but does improve acceleration. As for protecting the tranny, no, that's basically impossible. I know that's a popular term to throw around "Our software is safe, it's more reliable, it's better than the OEM" but that's a load of rubbish. We do everything we can to do it correctly and safely, but at the end of the day we're putting more load on everything so there's no way it will be as safe as it was stock.

Looks like a nice upgrade. Like, achan, the hash downshifting in sports mode would make me think about getting this. The problem to me seems like, in sports mode, it's not rev matching properly, as in manual mode it's fine (or I downshift sooner).

Arin, is the rev matching done in the TCU or the ECU? If the TCU, has the rev matching been changed in this upgrade.

I think they're saying that currently there are harsh downshifts and wondering if this will help.

Harsh being another word for badass, obviously.

Just got the TCU update. I have only driven it about 45 minutes but I can definitely feel the difference. The shifting is much more proportional to the power. Before, my car (APR flashed) felt like a belligerent, drunken MMA Heavyweight. Now, after the TCU update, the shifting is perfectly balanced, proportionate to the power. I wasn't brave enough to raise LC to 6,000 RPMs. I have it at 5,500 RPMs which I think is what stock is set to. I was consistently getting 1.6x 60' times so if it ain't broke don't fix it.

I did already test out the 3 LC points. That is definitely a very nice feature. There are times where I want to launch it, but not full on. Launching at 3,500 RPMs is really nice.

Anyways - that's my quick feedback. I'm sure I'll have more once I have a chance to put more miles on it. So far, it feels sooooooo much smoother now.

We've changed both the up and downshifting maps in drive and sport. I'm not sure I fully understand what you're describing though. Is the downshift, stock, harsh?
Yes. It's fine on a winding open road, but as you are coming to a stop the 3rd to 2nd shift makes it impossible to come to a stop smoothly. It feels like there is a delay in neutral and then it dumps the clutch in 2nd gear, when the engine is at idle.

Downshifting sooner in manual mode is very smooth, so I think it has something to do with the downshift to 2nd in sports mode happening just before the car is about to stop.

It waits too long to down shift. We adjusted that in D with the aim to make it smoother. Nothing is perfect, this is still a DSG, but it's pretty close to being awesome in my humble opinion.

Like with other tuners I've used on MANY cars (including the BMW's) it would be nice to have the tunes on a device that could be flashed by the user (similar to Cobb, SCT, etc). Just so much easier all around, especially for servicing. I think one of the reasons they DON'T do this, is because they have stopped allowing the transfer of licenses between cars. Having a device that allowed the user to unmarry and then reflash on a different car would then allow this again. That being said, this SHOULD be allowed, and you shouldn't be stuck using a license you paid for on only that car forever.

The dongle is vin locked to a single car as are quite a few of the handheld devices.

For us it's a matter of the customer experience. We want a dealer in the loop because they really do provide value. From a strictly financial standpoint, the dealer makes more than the cost of a handheld programmer. We could build one, go direct to retail and make more money. But, we don't like the customer experience that comes with handhelds. That's especially true when we're talking about 50k+ performance luxury cars.

We want our customers to have a local number they can call and a local guy they can lean on for primary issues (boost leaks, spark plugs, coil packs.. all the primary things that cause trouble on a tuned car). For most of our customers, the hassle of going to the dealer for a reflash to stock is a reasonable trade for the support they get from that dealer.

There's a switch toward the bottom of the gas pedal's travel that commands a downshift from the transmission. You can feel it more easily by slowly pressing the pedal down and feeling for a "click" just before the pedal bottoms out on the floor.

Probably time savings and convenience. Only so many authorized dealers out there, so you're looking at a few folks who likely aren't within an hour or two of their nearest dealer. Even here in the DMV, I'm over an hour away in regular traffic, each way. To save time would require taking leave to slug it down to NGP to get flashed. That's 30-45mins on a good day, all to get flashed back to stock and get the car to my local dealer, who happens to be less than 10 miles away from my house in the first place. And at least here, there's no just popping up without a wait. That's rolling the dice on whether they can see you within a few days, much less on the day you call. When you add in some of the authorized dealer debacles we've seen outlined on forums, you wonder just how compelling an argument this whole "customer experience" is.

Sean, this is easily remedied. Customer must get the initial flash at the dealer. Subsequent flashes should be able to be done by end user.

There is no argument for requiring the customer to go to a dealer after the initial sale, especially with Audi's vigilance with TD1.

I hope you guys reconsider. You are missing the boat big time. Run a poll and find out what the public feels!

and potential expense. If you have a car that ends up needing frequent dealer visits to iron out an issue, that can get pricey. My local dealer quoted me $110 to reflash back to stock. I'm assuming that means $220 round trip if I needed to do this before every dealer visit. That's ridiculous, but they can charge what they charge because they are the only APR game in town. I miss the days of mailing in an ECU overnight, or better yet, a completely separate ECU.

If you need frequent dealer visits, leave the tune out for a while until it is ironed out.

I don't think some of the people that think it is easy and a good thing to be able to flash their own car realize what is happening when the APR dealer flashes it. They log in to APR private server, which does diagnostics and saves the relevant files from your car so that when you want to get flashed back to stock and then tuned again, it will be done correctly with proper software revisions and such. Do you guys think APR should let every Tom Dick and Hairy <g> log in to their private proprietary server? And trust that the average knuckle dragger will be able to correctly negotiate the process? I know I wouldn't if I were them.

The dealer I know of does not charge to flash back to stock and then back again if you buy the tune from them. I am sure they might not be happy if you were wanting to do it every week, but a reasonable amount of times.... no problem.

110 dollars is incredibly overpriced in my opinion. It takes like 15 minutes. If it is 110 each way, out and in, then those guys should be wearing masks and a pointing guns at you when they take your money so that they will be properly attired while they are robbing you.

I had a 2009 M3 for 6 years. I had couple different tunes over the years. All flashable by me. All saved my stock tune on my laptop, as well as the aftermarket tune. My DCT tranny had a flash as well. It was remotely installed by the dealer over the internet. Remoted in.

Point is that there is no legitimate reason to not offer remote tuning, or subsequent user flash tunes. No argument holds. Only explanation is a money grab for dealers. Call me a cynic.

I feel no desire to do this at home. I like knowing they have a backup of my ECU.

Is it just time savings? For me the local shop allows me to just drop by without ever having to wait.

For sure, along with other things... 1-hour round trip for me, then another hour in the opposite direction to my dealer.

Secondly, when I was on a road trip from CA to Washington, I was so worried that I would have a mechanical issue when I'm in the middle of nowhere, because then what? Pay to have the car towed 500+ miles to an APR dealer, before you can have it towed to a dealer? This is the biggest concern! With my previous vehicles, I always kept the tuner inside the vehicle so it could be flashed back to stock at any time if this were to happen. Not something that hopefully ever WILL happen, but if it did that would be a really shitty situation to be in.

Luckily, my local APR dealer charged me just a flat one-time charge of $160 for unlimited flashes back-forth from stock. To charge $100+ per reflash is criminal... considering it takes 25 minutes and they just plug in and walk away for a bit. If APR is all about improving the "APR Experience through use of dealers" like Sean mentioned, they should crack down on that sort of stuff, to remain in line with this same philosophy!

Eurocode in Torrance has been great, so I do agree this dealer improves the experience from what I've experienced myself. Just couldn't imagine being bent over each time the car has to be flashed for a dealer visit.

Brooklyn

09-02-2015, 07:15 AM

Agreed that if you're having issues with your car, iron them out before getting tuned. That said, there's no guarantee stuff won't pop up post tune. But generally this goes back to the better customer experience being an option for customers to install the tune themselves. Sure, the vast majority (heck, including maybe me) would rather opt for a dealer. I can barely download a MP3 without worrying something might go south in the process. But I just might opt for the self-install option if any of a number of conditions exist that would make visiting a dealer problematic. And yes, I think the cost to reflash is ridiculous, and I think APR should consider that process a necessary option for those purchasing their product given Audi's warranty sniping operation. As part of their requirement, they should either include a certain number of reflashes as part of the price, or at a minimum take steps to prevent their dealers from gouging the fuck out of customers who are faced with either not buying their product, or paying whatever price their local dealership decides to charge to avoid the even bigger financial risk should the Audi dealership detect the tune. Concur that $110 is absolutely ridiculous, but I've got the email from NGP saying that's exactly how much they charge for this service.

How often do you anticipate being flashed back? I am thinking once a year for the regular service, maybe twice tops if a mechanical issue arises. To have it to enjoy all the rest of the time, a one hour drive is nothing in my opinion.

I agree if you were on a road trip and the car became un-driveable, that poses a challenge, but what is the likelihood of that with an almost brand new car? In that case, there are dealers all over and the nearest one is likely much closer than the 500 mile away one at home.

I also agree that of course it would be more convenient to be able to do it yourself. But thats not the way it is. APR would probably sell more if people didn't have to travel to get it. I am sure they know this. But after weighing the pros and cons they have apparently decided that the reasons for not offering it that way outweigh the reasons for doing so, even though they would sell more AND keep more profit for themselves as was mentioned earlier. Thing is, not everyone is as tech savvy as others, and they would be fielding millions of questions from tech challenged individuals, maybe bricking a few ecu's by idiots pulling out the USB cable halfway through etc. Now you have a stupid AND angry customer.

Having your car tuned is risky and inconvenient in several small ways, and this is just another one of the risks and minor inconveniences that are part of the deal at this point. If you want your car to be twice as good as it is from the factory, you accept those things along with the increased enjoyment of the driving experience.

Nothing wrong with appealing to have the policy changed though. Maybe they will eventually let people do it themselves which does have its upside. After all, there was a time not long ago when they said the 4.0 would always require a bench flash. Since then they have figured out how to do it through the port.

For sure, along with other things... 1-hour round trip for me, then another hour in the opposite direction to my dealer.

Maybe not high on a brand new car... but what about in 3 years or so when you still have a warranty, and something completely unrelated to the tune goes south and makes the car un-driveable?

My buddy has a 2012 BMW 335IS and just last week his turbo outlet hose blew apart when he was driving to see me (90-minutes from home)... He has a hand-held tuner, pulled off the tune on the spot and then right to the shop... no worries! Maybe it's on my mind for that very reason, literally just happened last Wednesday for him.

If the price is 110 for in and out, that is a total of an hour of their time, so I guess it could be justified if that is their shop rate. (Not really a "Money Grab" any more than anything else one of their techs is doing for an hour and charging for. That extra hour of labor a year isn't gonna make any shop rich.) It seems like a lot to me, because some guys don't charge. But 110 each way (220 for in/out) is crazy IMO. See if you have another dealer nearby. They might be a lot more reasonable. Maybe a little farther away, they might agree to no charge, x amount of freebies, or a small charge on subsequent flashes to get the initial sale.

Yes it would be bad, but the worst case scenario is that you can have a car shipped across the country for 1000 dollars. These are nearly 100k cars. Certainly anyone that owns one has a few hundred for a tow to the nearest APR dealer in the event of this tragedy. Yes, it would suck. But its not the end of the world. To deprive yourself of something awesome that you want due to every possible eventuality is not the way I roll. I understand that some people are not like me... and that is a good thing!

That piece is completely unrelated to a TCU tune. It is designed to minimize structural movement of the transmission, and it does. I have it and for instance it makes the more aggressive downshifts in S mode less felt in the car, even tho you still hear them the same.

It will still do what it does whether you have the tune or not. Just like the TCU tune will still do what IT does.

I was curious, given that the TCU tune from APR also apparently helps address the rough downshifts. I also recently received the latest TCU software update from Audi to help address the rough downshifts, and it definitely has made a big difference. I'll be curious to see how the APR tune will change things, let along the 034Motorsport Trans Mount Insert.

In the mean time the ECU tune is as good as all the posts and how the car should have come from Audi.

There is no removal / bench flashing TCUs, but what it sounds like is you had a version we haven't seen yet, which is normal. In such case, the dealer just needs to send us an extract and then we can write software for your vehicles code. They do this by plugging in and following a few on screen prompts (no TCU removal or anything like that.)

Excellent, glad to hear, thanks for the reply Arin. I'm sure my dealer will be in contact with you Tuesday.

That pretty much went away for me with some updates from the Audi dealer that were revealed in some other threads about the topic. That is engine response to pedal input so the TCU tune will not really address that I think

Not entirely true... some of that lag is a side-effect of the dual clutch transmission actually having to physically engage/disengage the clutches as you would with a manual clutch pedal. When coming to a stop the TCU is telling the transmission to open the clutches... and if you suddenly hit the gas WHILE it's still opening the clutches, theres' a slight delay before it can physically close them and engage the gear smoothly again.

That being said, I suspect if this speeds up the shifts themselves as APR claims, this may just help that very issue!!! Audi providing you updated software may have also addressed some of this?

I also have the TSB updates and I still feel it in certain circumstances. On the somewhat rare occasion I'm in S mode while driving around town I rarely feel it maybe because the car tends to already be in the "right" gear.

If this was the case, you would have throttle engagement with resulting increase in engine rpm without movement of the vehicle. When I have experienced the lag, there was no engine response to throttle input. Unless the tranny's unreadiness over rules throttle input ( and I don't think it does because there are many cases when I smash the throttle and the RPMS leap up but the tranny doesn't grab right away) it seemed to me to be throttle related.

The lag issue has been hugely improved if not completely eliminated in my experience with dealer updates.

If you have APR Stage one ECU tune, the TCU tune is a must. Although all the power with just the ECU tune can be fun in a way, the stock tranny tune is ill equipped to deal with it properly. You don't fully realize what a half assed combination it is until you upgrade to the TCU tune. 30 day money back guarantee to find out for yourself. What other reasons do you need? [:D]

The car is far smarter than that... it controls the throttle and clutch engagement at all times, some parameters relying on others. So yes, it will NOT increase throttle and engine revs until the transmission tells the ECU that its ready for it.

This is a side-effect that MANY cars (makes and models aside from Audi and Models other than the S6) experience that are equipped with a dual-clutch transmission. My Ford Focus that had a dual-clutch had WAY more of this same lag... sometimes like 1-2 seconds! Was dangerous at times when trying to suddenly shoot into a gap or merge in stop and go traffic.

Just one of the few "cons" of having one... there's still shifting going on, people just don't expect any delays because mentally they feel like they're driving an Automatic.

To anyone that has gotten the TCU tune - do you still experience the 'jolt' that happens going from 1-2 (from a dead stop) if you get even a hair too heavy on the throttle? Feels like the dual clutch plates are struggling to engage properly or something. Or has anyone else experienced this stock?

dennisg

09-09-2015, 07:20 AM

Of course I believe the car is very smart but it is only as smart as what some human has programmed it to do. Apparently it is capable of doing it pretty close to right seeing that the updates have improved it immensely. Once the humans had a little more time that were able to get it almost right.

You may be right that the tranny overruled throttle in that slow moving circumstance but there are other times that throttle input creates lots of rpm with no tranny grab. Maybe that is for rev matching anticipating a kick down to a lower gear?

Works very nice overall now after some further attention by some other smart humans! ;-)

This is getting off track I know but as far as everyone speaking of the updates they received from the dealer I'm assuming you have 2013 models? I have a 14 and with all my reading of posts it seems everything related to these issues was only addressed with updates to the 2013 model. Am I wrong?

Everyone told me I'm wrong (it doesn't exist), but I have a 2016 and asked the dealer to update my TCU software. Now what they did, I don't know, since I kind of went through the "back door" with my salesman buddy. But the rough downshifts smoothed out and the car no longer has that pop when aggressively up-shifting. Personally, I like it less now. Hoping the APR TCU will give me a little aggression back.

Most of the prior complaints have been with the 2013 model year. My ECU and TCU updates at the Audi dealership seem to have made things much smoother, but I'd by lying if I said it was buttery smooth shifts all the time. Either way, I'm personally looking forward to taking my S7 into the local APR shop and getting the performance updates for both ECU and TCU!

Anybody that has the flash, does it get rid of the "hesitation" that we experience when you brake and then try to get on the gas quickly?

There's two factors at play in what you're describing.

The first is in the ECU, it's called tip-in. That's a delay from the time you push the gas until the engine responds. We eliminate that.

The second is in the TCU and it depends on what you did before. If you're decelerating and suddenly push on the gas, the TCU gets a little confused. Stock, it stays in the higher gear until you're stopped. We opted to downshift early. Accelerating out of a stop stock requires the transmission to downshift first. That takes time and the engine is held back while the transmission does its thing.

Our TCU tuning philosophy is built around "positive driver action". What that means is that the software is looking for you to do something assertive to tell it what you want. Slow decel and then mushing in a little throttle isn't very assertive and it will give you a similar non-assertive response. It will be in a lower gear with the tune and without the tip-in delay, the reaction will be fast but minimal. Slow decel combined with a higher rate of throttle input (not necessarily more throttle, just applied more rapidly) will give you an assertive response. It will stay in the lower gear and accelerate in a linear fashion. Slow decel and a very rapid throttle input to above 50% will engage max acceleration mode and it will bounce your head off the headrest.

Good to hear. What I'm describing is probably similar to what you are describing. Basically I'll be slowing down on the brakes (hard/soft doesn't matter), let off at 5-10mph and then get on the gas hard. That causes a 0.5 - 1 second pause before the car accelerates and you get that head snap back. Hard to describe, you really have to feel it, but sounds like it should at least be partially addressed. Thanks.

After going back to my S7 today after two weeks of being in the shop for some repairs, the tip-in was immediately what I felt again and honestly didn't enjoy after getting used to the responsiveness of the A7 transmission. I'm really looking forward to the TCU tune for eliminating this. I'd even go so far to suggest that APR needs to trump the elimination of tip-in as a major feature of the TCU tune.

What you're feeling is a combination of both ECU and TCU. Eliminating the delay from the accelerator is ECU. Selecting gears earlier prevents a delay while the transmission shifts. Combining both of those changes is where we find the awesome.

They do this by plugging in and following a few on screen prompts (no TCU removal or anything like that.)

Unfortunately not a simple as I had anticipated. It seems TCU extraction has to be done directly from the TCU and not from the OBD-II port. Had to schedule another appointment for Monday to have it put up on a lift and extracted with special cabling my dealer has to obtain.

Its a simple flash thru port as long as they have cracked the code on the one you have. If not, they can do an extraction and figure it out pretty quickly. Then they will have that one in the file and other people with the same one can then get the port flash. If you wait long enough, they will likely get yours from someone else. Thing is, the extraction on the spot over the server isnt that bad. Initially, the ECU tune required a bench flash, and if they didn't have your version figured out yet, you had to send your ECU in for an extraction or wait for someone else to do so. People were legitimately hesitant to send it in. After all what if it gets lost in the mail. "Honest Mr Audi Dealer, I came out of the restaurant and my hood was open and the ECU was GONE!!"

dennisg

09-17-2015, 03:10 PM

I am not sure how you got that the tranny software "reduces the life of the transmission" from what Arin said. He said that adding power with the ECU tune obviously adds stressors to the transmission, as it does to every other part of the drive train so it cannot possibly make it safer than stock. Nevertheless, it may hold up just as long, who knows?

The tranny with the tune now expects what the power is doing and may actually be safer than just the ECU tune with stock tranny tune.

As I said in another post somewhere, the stock tranny tune seems confused as to what to do with the stage one ECU tune. Another guy likened it to the car being like a belligerent drunken MMA fighter. You don't realize what a half assed combo it is until you get the TCU tune and it all comes together.

Nothing to wait for, 30 day money back guarantee. I doubt that you will go back and have it removed, unless you suddenly need a few bucks for a life saving operation.

You are already on the APR bandwagon. Too late to go back to GIAC to try to save a few hundred. Just go get it and enjoy the whole enchilada the way it was meant to be experienced. You won't regret it. Just a couple extra pieces of dirty paper... ($100 bills) [:D]

Arin@APR

09-17-2015, 04:19 PM

yes, that's the one...

Yeah, I know some tuners like to tell everyone everything is safer than stock, but let's be real. We remove the launch limiter and let you launch up to 6000 rpm. How could that possible be as safe as stock, or safer, on the 1000th launch if stock prevented you from doing more than 200?

Now, that doesn't mean it's going to explode, but that's not the argument. :)

^ Max shift point is when the software update raises the factory rpm shiftpoint to higher one to get more power and revs out of the motor. For best results yes shift at that higher rpm but you don't need to all of the time unless you're really getting on it all of the time.

Understood.

Assuming that apr tcu is done on stage 1 car, which is faster? Flooring at pedal in S mode vs. Manual mode shift at 6,550 rpm

Isn't peak power around 5k RPMs for our motors?

That's what I meant. I assume that shifting earlier may faster than shifting at redline.

Arin, please elaborate this.

Stage 1 dyno plot shows peak HP around 5800 and pretty flat at that point. I can only assume holding to max rpm while at near max HP would allow for max acceleration. Once APR recodes my extracted software and I can get back to my dealer (trip #4) for the upgrade I'll gladly let you know. [;)]

I believe it's mostly about (averages over a span of time spent in a gear at WOT. Not a peak) but I was looking at the graphs which might answer your question a bit.

Referencing APR's site for a 93 octane (I'm only looking at the Wheel hp/tq) graph for their Stage I ECU upgrade VS stock, and I see the following:
____________________________________
C7 S6/S7, Stock:
Peak HP reached at roughly 5700 - 5800 RPM
Peak TQ reached at roughly 2200 - 2800 RPM (kind of flat there)

C7 S6/S7 After Stage I 93 tune:
Peak HP reached at roughly 5500 RPM
Peak TQ reached at roughly 3000 - 3100 RPM
_____________________________________
C7.5 S6/S7 stock:
Peak HP reached at roughly 6000 RPM
Peak TQ reached at roughly 2600 - 2800 RPM

C7.5 S6/S7 After Stage I 93 tune:
Peak HP reached at roughly 5400 RPM
Peak TQ reached at roughly 3200 RPM

I don't have the exact shift point figures yet (for drive and sport) but it's higher than the S6/S7 stock turbo. What may not be entirely obvious is that a higher RPM doesn't mean faster times. You essentially want to keep axle torque as high as possible. If that means shifting earlier in the RPM band, then your acceleration time will increase as lateral G forces should be higher. So, in the example of the S6/7 turbo, we're shifting in the mid the low 5000 range on the taller gears.

Question about acceleration, and shift points for staying in the more accelerating RPM range averaged over the gears.
If peak acceleration is where highest axel torque is, wouldn't the ideal RPM's for acceleration purposes for say a C7 S6/S7 stage I 93 tune be in the 2700-3800 RPM range since the highest average, and peak torque at the wheels happens to be measured in this range? I can tell you the car pulls much harder and accelerates faster far later in the RPM band than this high torque range. Torque is lower in the 4000-6000 range but the car pulls harder... That makes me wonder if it's best to stay near the higher end of the upward power curve during all out acceleration, rather than in the higher torque curve. I know gearing makes things more complicated than a dyne graph, but I'd like to hear more about this specific to these engines on the S6/S7 C7 & C7.5.

Question about S6/S7 C7 vs C7.5 tunes.
Why are the Stage I 93 octane graphs so different for the same engine between the C7 & C7.5? Is this something you expect the C7 to be able to catch up on with a revisited/refreshed software update?

Assuming that apr tcu is done on stage 1 car, which is faster? Flooring at pedal in S mode vs. Manual mode shift at 6,550 rpm

Sport mode has shift maps remapped to closely match axel torque. Use that for the fastest acceleration.

If peak acceleration is where highest axel torque is, wouldn't the ideal RPM's for acceleration purposes for say a C7 S6/S7 stage I 93 tune be in the 2700-3800 RPM range since the highest average, and peak torque at the wheels happens to be measured in this range?

Axel torque is different than the torque you'll read on a dyno graph. The actual torque at the wheels gets multiplied through the transmissions gear ratios. If you shift too early or too late, the next gear will result in lower axel torque than is possible by shifting at the correct point. You have to find the balance. This can be done on paper using the wheel torque figures, gear ratios, and tire sizes. It can also be done on the road using accelerometers to monitor gforces with the ultimate goal of keeping them as high as possible at all times through shifting at the appropriate point.

They are similar but we got more midrange out of the C7.5. It's possible there could be an update for the C7 at some point if we're capable of the same on that platform.

Ah, yes torque multiplication. I'll get around to building my calculator. Thanks!

Ok guys I've decided to get the TCU soft for my st3 s6 , I went to my dealer , spent an hour off work , didn't flashed the car , the dealer didn't had cable , ok next time . Getting a call from the dealer , the cable is here , spending another hour off work , that was wrong cable , the correct cable is on the way from APR now , we would have to put the car on the lift , get to the plug from the bottom , download the current TCU soft , wait few days and flash the TCU , so most likely the dealer will charge me for downloading , uploading , assuming $200 , that what he charged me for st1 labor , so , $1700 st1 , $1300 st3 , $1300 TCU , labor not sure yet. Sounds a bit crazy , not to mention all my time of work which is not cheap , $5000 total for tune the car ... Plus all the time that waste , I hope it's worth it . And btw , I want brake boosting activation so here is some labor again , why we can't choose this option while flashing the first time ? We have to put request and wait a few days .

You're correct. But it is hard to get 100 or 104 octane gas from here.

For your stage 3 setting, did you only need the turbine set? What parts did you need for turbo upgrade?

I am considering to get used rs7 turbochargers somewhere if the install is simple as plug & play.

My understanding of the stages so far:

Stage 1: ECU Tune
Stage 2: ECU Tune, Downpipes, exhaust (and possibly intake?)
Stage 3: All of the above, plus RS6/7 Turbos (and possibly turbo cooler system?)

Stages 1 and 3 are currently available; Stage 2 is still in development (waiting on the downpipes). APR, correct me if I'm wrong.

I had the dsg tune done yesterday and noticed some small differences like in d the transmission is more responsive. I plan on using the entire 30 days to evaluate whether its worth the 1k. With the weather cooling I am going to try and hit the drag strip in the next few weeks. Too bad it wasn't done prior to the audi owners event last week where I spent 30 minutes on the track chasing down r8's. Had both tunes done on the rs6.

I am considering a TCU upgrade, too. I look forward to your feedback.

Here are the requirements:

Stage 1 - Nothing, just the ECU.
Stage 2 - Stage 2 ECU Flash and high flow donwpipes (not released yet).
Stage 3 - RS7 turbos and different spark plugs along with our Stage 3 ECU flash.

At Stage 3, if you want to hit our advertised results, you're going to need downpipes and a DSG tune for higher RPM. We really recommend an intake upgrade, such as a drop in filter, and cooling upgrades too.

*note, we don't really call it stage 3, but it just makes it easy to reference it here as that.

What kind of gain roughly is expected with a stage 2? Do the high flow downpipes wake the stock S6 turbos up much?

side note:
Yeah, typically an OEM turbo setup is generally still in a Stage 2 territory if it's not an aftermarket setup. An RS turbo bolt-on falls into this category in my opinion... Stage 2 +... Where a custom turbo setup more capable than the RS7's would be definitely in the Stage 3 if I'm going by other performance turbo car stages for reference. I can see for ease of understanding considering how common the RS turbo swap may become it may be called the Stage 3. Are there plans for a Stage 4 or / aftermarket turbo upgrade?

What's the most power seen on the DSGs so far? Seems both the S/RS engine/tranny setups are pretty solid so far with no reports of hp/tq caused failures. I'm waiting for the first one to break. When it does, I wonder what the support for beefing up those will be.

The RS7 turbos are NASTY. It's not terribly expensive (considering that it's two turbos and an $80k+ car) and the results are nothing short of fantastic.

So a few days on the tune one of the benefits is the immediate power it is always in the right gear. Kickdowns are aggressive and bring a huge smile to your face. With both tunes this is how the car is supposed drive.

TCU upgrade complete. As other early adopters pointed out, the car just seems to be in the right gear now all the time. Definitely matches well with the ECU tune. I have not had a chance to try launch control due to the rain. I have the max set to 4000 since I discovered stock 5000 is too much for stage I with street tires even on a sticky drag strip.
The most noticeable things are in manual mode. I left the automatic up shifts on as I have no need to bounce the rev limiter and I am glad to see it works as I had anticipated it would and goes right to redline as advertised before shifting. Whereas stock I feel sometimes shifted a bit early in manual mode. The faster paddle reaction is also noticeable. Might add more comments as I get more seat time.

Just got mine done. Worth .... Every ..... Penny! I'm absolutely loving my car! It has truly transformed it to another level. I would go as far as saying that the leap in performance from to this TCU tune is at the same magnitude as the leap from stock after the ECU tune. It does make the car sound louder post-tune, comparing to applying the same throttle input pre-tune, as the turbos are working harder (for a lack of better word) and exhaust note is more pronounced. Shifts are now lightning fast! Much faster than pre-tune. On highway, I also feel a sense of stronger torque when accelerating. It just keeps pulling hard. Also, when turning left from a stop at a interaction, the acceleration is shockingly immense and really smooth! Overall, the whole car feels more alive!

has anybody gone with the manual upshifts in manual mode and have any feedback? this is one feature that is making me lean towards apr vs. giac. thanks!

Maybe a little. :)

I'm torn between getting this tune and GIAC, since my regular shop is a GIAC dealer and they've been awesome. I don't like what I see as GIAC's solution/workaround to stuttery low-rpm acceleration, though, and Eurocode (APR dealer) is closer to me...and they make the suspension components I'm going to want.

I was advised not to disable the automatic upshifts in manual mode by my APR dealer tech. He told me that his other customers came back to enable this feature because they couldn't shift fast enough and kept hitting the limitor when using launch control.

I may have went a little overboard but my praise for this tune hasn't changed. I notice that this stuttery low rpm behavior is gone during my seat time so far. Also, in D mode, the power delivery is smoother and linear especially in very low speed (in residential area). I'd always have a grin whenever I notice how the tune improve my daily driving. I really didnt like the quirky transmission before but now I'm really loving my car.

Do you know your TCU box code / revision?

no , I didn't ask , I probably can check with vagcom , but the question is general , if there is a different between st1 st3 or no .

Should just be shift points. I'm checking now and will get back to you (may be tomorrow). If you have a vag-com, let me know the TCU box code / revision. Should speed things up:

just in case if that would help , the request came from Sublime Speed Technology from Omaha NE , 2015 S6 (I don't think there is more S6's here )

Does that apply to other countries as well, like New Zealand?

Curious about this 10% discount business I saw mentioned! I had my tune done just before the sale was announced - wondering if the discount will be pro-rated if I return for a TCU upgrade? I emailed Greg about it, no response yet.

Shoot me an email when you know the box code / revision. I'll need that and then we can make the file for you.

Thank you!

2014 S6
got my TCU upgrade 2 days ago. cannot speak about a stock car, but on my APR stage 1. very noticable difference. D mode can be used off track all the time(vs switching to sport mode 1/2 the time). Sport mode is like a race car. The two should only be sold as a unit.
got it with a 10% discout too. paid for my transmission mount insert. I never launch the car, never will, never use manual mode (a sin I know), and still love the upgrade. Thanks APR. Waiting a while for this since the other guys(g something) did theirs.

nice

I'm rarely in S mode now... told some buddies at work that maybe the car is too fast. I'm scared to blow it up. Drive mode is nice and aggressive. Sometimes Ill pop into sport mode when I'm slowing down to impress some of the tennis moms out on their walk. :P

Just curious....how is the drivability if you get the TCU flashed and then drive with the ECU in stock mode? I am assuming that you still can't put the TCU in stock mode via the dongle, right???

If you get the TCU tune in addition to ECU, do you recommend flashing both back to stock for service to try and avoid TD1? My installer charges a "hook up" fee for flashing but wants to charge two, one for each the ECU and TCU.

After having the tcu tune for a month and trying to put into words the difference that you feel. Second gear which takes you up to 60 mph if you hit it from a roll at about 1500-2krpm it feels like the tires want to break free it pulls unbelievably. 1st gear is so quick and you have to come to a full stop to have it get into first, it seems you spend a ton of time in second gear and with this tune the transmission is just spot on with the ecu tune. This is in sport mode without using manual.

I have the TCU done with BETA 0.9 3 days ago , I can tell for sure there is huge different even with basic TCU tune , I don't know what APR do but I have to turn the traction control off , otherwise I'm spinning all the time , even if I'm getting on it from the roll second gear . I like it , more feedback next week , I have a 6 hours drive and 1/4 mile testing .

It's great. Was having some ECU problems and waiting to get the v1.1 update, so put it in stock mode while still keeping the TCU tune in place. Super fast gear changes, nothing rough at all. More "drive-able" than stock.

i had the dsg tune done yesterday and noticed some small differences like in d the transmission is more responsive. I plan on using the entire 30 days to evaluate whether its worth the 1k. With the weather cooling i am going to try and hit the drag strip in the next few weeks. Too bad it wasn't done prior to the audi owners event last week where i spent 30 minutes on the track chasing down r8's. Had both tunes done on the rs6.

run any quarter miles yet? Curious of the 60' times or 0-60 and 60-130 times...
