We're excited to announce our Engine Control Unit (ECU) Upgrades are now available for the Audi S4, S5, and SQ5 (B9) 3.0 TFSI engine with the Bosch MG1 ECU! Expect massive gains with up to 431-480 HP and 467-549 FT-LBS of torque on tap, depending on octane, from this simple software upgrade. Additionally APR Plus is available with 431 HP and 467 FT-LBS and comes with a factory term limit matching limited powertrain warranty!

Our new suite of MG1 ECU software comes after months of extensive research and development that is typically absent from the aftermarket. Our upgrade makes the engine more powerful and more exciting. We’ve extensively calibrated the system to work flawlessly on the track, while retaining safety routines to protect your engine in the most demanding scenarios. This was all made possible by our engineering team's pursuit of perfection. Development vehicles were outfitted with additional sensors, including turbo shaft speed sensors, thermocouples, transducers, and more, along with our high speed direct RAM logging equipment, to feed valuable data to the team for analysis. After thousands of hours of testing and tuning we created new calibrations that are fine tuned for several octanes, including ethanol, and contain hundreds of map changes, with a vast array of safety features built in.

Hardware Requirements

None required, however, an APR Intercooler (https://www.goapr.com/products/intercooler_b9_30t.html) is highly recommended.

Prices

$1,299.99 USD Retail (APR Stage 1)
$2,299.99 USD Retail (APR Plus with limited powertrain warranty)

Other Notes:

The factory intercooler is tiny. We highly recommend upgrading to the APR Intercooler System (https://www.goapr.com/products/intercooler_b9_30t.html). Also, for this reason, dynoing on a dyno with an undersized fan will cause the ecu to dial back power to protect the engine. The ZF8 HP typically takes several dyno pulls to get up to temp and deliver proper power figures (stock and tuned). Lastly, in freezing weather E85 may require more cranks before starting.

How to Purchase

This ECU must first be unlocked before software can be installed either by APR or an APR Dealer (https://www.goapr.com/dealer/).

If the ECU is locked, you have two options:

Option 1: Send us your ECU

Send us your ECU. We’ll unlock it, install APR software, and ship it back. The unlock process is free. Ground shipping to the continental USA is free. Follow these steps and watch the video for details on how to remove the ECU.

Step 1: Purchase the ECU Upgrade (https://store.goapr.com/products/APR-ECU-Upgrade-%252d-3.0-TFSI-EA839-%28B9%29-%28ECU-MUST-BE-SHIPPED-TO-APR%29.html).

Step 2: Fill out this unlock form (https://app.smartsheet.com/b/form/7b0ecbe6a94b4ca9aa4e94d7841d20b4) and select VW/Audi MG1 under unlock type.

Step 3: Mail your ECU to APR, 4800 U.S. Hwy 280 W, Opelika, AL 36801, USA, and include the last 6 of your VIN on the outside of the box.


https://www.youtube.com/watch?v=VMNKkeK_CRY

Option 2: Visit an APR dealer

Visit an APR Dealer (https://www.goapr.com/dealer/) and purchase the APR ECU Upgrade. They will remove and mail the ECU to APR. We'll unlock the ECU, ship it back. They'll reinstall the ECU, and install the software.

Please note

At no time during the unlocking process is the ECU opened or physically modified. If the ECU is flashed back to stock, it will need to be unlocked again. If the ECU currently has APR software, and there is an update, a new stage, new feature, or you want to switch octanes, software can be installed by an APR Dealer (https://www.goapr.com/dealer/). Also, vehicle manufacturers issue many ECU part numbers and revisions throughout their vehicle lineup. As such, some ECUs may be temporarily unavailable as new parts and/or revisions are released. If the vehicle’s ECU part number and revision is known (https://www.goapr.com/support/boxcode.php), availability can be checked at any APR Dealer or by contacting APR.

[DiscoDan]

Very impressive gains with just a stage 1.

91 pump gas is the norm here, but I can get +85 hp and over 100 extra torques, very nice.

Need to locate a nice APR dealer in my area and get this done

[DiscoDan]

Just realized that a dealer will just pull the ECU themselves and send it in. I was under the impression that it could be done there and I drive away shortly thereafter. Either way, APR is still going to get my $

[mtbmaniac]

SCR in Loveland is a very reputable APR dealer. They have tuned several of my past Audi vehicles with APR as well as installed suspension and exhaust modifications. I highly recommend them!

[eruben123]

Props Arin - being first to market on this stuff is no small feat, and the power numbers are really really impressive here. Excited to see what the future holds for this new 3.0 platform.

Do you think at some point down the road the ECU will be able to be unlocked without getting shipped in? And do users have the ability to switch from 93 to E85 without visiting a dealer?

[Arin@APR]

Yes and yes

[subaruski]

Wait. So you can switch between 93octane and e85 without visiting dealer? Or is that a soon to come feature?


Yes and yes

[RoofRails]

Has it been 2 weeks already ??

Arin,

Is the speed limiter removed or bumped up? My SQ5 was limited to 130 because I purchased the All Season tire option.

Numbers look great - your team did a great job.

[Arin@APR]

It’s bumped to the max, which is like 300 or something like that.

[chawski]

The disabling of auto start/stop is enough for me! The added power is a nice touch ;)

Very interested to see how these do. I know we’ve been waiting a while for this, and sounds like it was worth the wait!

[spindlewood]

Arin,
Has the throttle response (lag) been improved?
Also, do you test impacts on gas mileage for daily driving?

I appreciate your answering a million questions on multiple threads.

[Arin@APR]

We’ve adjusted throttle lag and pedal maps on the ecu front to help. Gas when cruising should be similar, if not better. When you’re going full tilt, you’ll use more.

[spindlewood]

Arin,
You link to the S4/S5 intercooler above. Any idea when they'll be available for the SQ5?

Also, any link to the S4/S5 installation instructions? I'm presuming removing the bumper and install is pretty similar?

I too inquired on this front and he opined in the S4 thread that it's currently in works. The intercooler is the same it's merely the mounting hardware that's being developed.

[spindlewood]

I'd love to see any comparison with the AWE intercooler (available now for the SQ5) that shows the APR intercooler is worth waiting for and worth the extra $$. Getting an apples to apples comparison is even harder than with tunes.

It's in the works now and should be ready by summer.

[Mynavi]

Just received and installed my ECU and took it for a quick drive. All I can say is WOW!!!

I purchased the tune a few hours after being released last week. Removal was simple thanks to APR’s video. APR received, tuned it, and mailed it out all in one day. I paid for next day air both ways as the SQ5 is my only vehicle.

The increase in torque was noticeable immediately. I can feel that the car is so much smoother now. That delay that I would get is now nonexistent. I jumped on the highway and there’s no need to have the car downshift to pass, simply roll into the throttle and the car starts to pull.

I didn’t drive it too hard as it’s raining here, but I can’t wait to see how she pulls from a stop later.

[Arin@APR]

Awesome! Thanks so much for the feedback!

[Arin@APR]

I got some requests for all dynos on one graph (at the wheels). Here you go!

When tuning the new 3.0 TFSI, we went the extra mile to ensure our tune was not only powerful, but safe. We added numerous sensors to the engine and monitored the data with a Motec Dash. We added a turbo shaft speed sensor, compressor discharge temperature and pressure sensors, exhaust back pressure and temperature sensors, and various other pressure and temperature sensors throughout the system. With this data we can make sure we don’t overspin the turbo, run the turbo and engine too hot, or experience excessive back pressure. All of these things can hurt the engine long term, and without adding sensors, we’re not able to push the engine as hard without confidence. In our industry, this is not typical. It means sacrificing parts, and buying expensive sensors, removing engines from cars, etc. It's expensive, but it's part of what makes us different. #goapr

[phillyquattro]

Are there plans to work on a stage 2 file?

[Arin@APR]

Yes, that's up next for the car.

[crazy4cars]

what is needed to run E85 beside the tune?

- - - Updated - - -

what is needed to run E85 beside the tune?

[Arin@APR]

E60-E85 ethanol.

[crazy4cars]

my question was in order to run straight E85, there is no need to upgrade the injectors or fuel pump? how do I switch from pump to E85 map?

[Arin@APR]

No hardware required. I would suggest a content analyzer though.

To switch, you can have a dealer flash the file.

Im the Ignite Racing Fuel importer, we are good.

[HurrayFive]

Hey Arin - is 80A907559D a supported box code for the SQ?

[Arin@APR]

Newer SQ5? Should be! Send it in and we'll extract and let you know. Thus far all have been as we've tuned each of the ECU families / variations.

Here’s a preview of our upcoming #B9 intake system. This version is for the #RS4/#RS5, but we also have an #S4/#S5 system and eventually #A4/#A5. We’re upgrading every aspect of the intake, from the restrictive turbo inlet system, to the airbox, down to the front scoop. Each flow more, and thanks to upgrading the turbo inlet, it can be used on larger turbos, and actually reduces a critical restriction! Without it, intakes may not fair so well. The carbon fiber weave matches the OEM pattern and direction. The filter is absolutely MASSIVE with a ton of surface area. There are even extra openings to cooler locations to make sure this system can breathe! Stay tuned for performance figures and pricing later this summer. And stay tuned for a different version for the #C8 #S6 / #S7. #goapr #b9s4 #b9s5 #b9rs4 #b9rs5 #b9a4 #b9a5 #c8s6 #c8a7

Just went for a quick spin after getting my ECU back today. Complete night and day from stock.

You notice a little extra something pretty quickly. Very smooth overall. Once the car warmed I gave it the beans and she came alive. Definitely a worthwhile upgrade!

Sorry no video. Just wanted to give my initial impressions for folks that might have been on the fence.

It's been a long time coming needless to say, but it's worth it. I'm sure you'll see folks start posting videos shortly.

I was coming from an F80 M3 and I was missing the power. Definitely not comparing to the F80 but the SQ5 definitely feels proper quick now, especially being my family hauler. This is my 3rd APR tuned car so good to be back.

Which tune - 91 or 93?

[DiscoDan]

Arin,

Can you confirm that my ECU is good before I mail in? Or should I call APR direct with this info? -Thanks

Box Code: 80A 907 559 J
Software Revision: 0001

[notquiteanewbie]

Which tune - 91 or 93?

I went with 93. Easily accessible in my area.

[Arin@APR]

DiscoDan I haven't seen anything that would indicate it's an issue. We've done several SQ5 ECU families, North America and Rest of World.

[nemesis1915]

First of all well done APR a lot of people were waiting for this and you have not let down from what I read!

Hi Arin my question from Australia!

1) when can we see the SQ5 upgrade for us Ozzies
2) will all our APR dealers be equipped with the knowledge to do this
3) are the APR intercoolers available for the SQ5 in Australia as I could not see it on your website
4) ETA for the air intake on the Sq5 in Australia and what we looking at for price?

Also are if you are able to, how far are we pushing the engine! are we maxing out injectors? and what boosts are we looking at ?

cheers mate

[Arin@APR]

First of all well done APR a lot of people were waiting for this and you have not let down from what I read!

Hi Arin my question from Australia!

1) when can we see the SQ5 upgrade for us Ozzies

The 3.0 TFSI S4/S5/SQ5 release was global. It's available today. The ECU must be unlocked, so unless someone has a tool to do that (we havent' shipped our tools yet), the ECU must be sent to APR.



2) will all our APR dealers be equipped with the knowledge to do this


Yes, I released the info globally on March 27th. PM me with the dealer you spoke to and I'll make sure they have the info.



3) are the APR intercoolers available for the SQ5 in Australia as I could not see it on your website


The SQ5 and S4 brackets differ, so we'll have to make new brackets for the SQ5. That's in the works now.



4) ETA for the air intake on the Sq5 in Australia and what we looking at for price?


No ETA / No Price / No confirmation. The SQ5 is dramatically different than the S4, so the systems are not plug and play. It will require making a new system. That's not confirmed quite yet.



Also are if you are able to, how far are we pushing the engine! are we maxing out injectors? and what boosts are we looking at ?


The only thing majorly restricting power on stage 1 is the turbo itself. With an intercooler, IAT drops and power improves. With a full intake system we can improve the pressure drop before the compressor wheel and improve power. With a new downpipe / exhaust we can improve back pressure and lower turbine shaft speed and make more power. On Ethanol, perhaps with items maxed, we may find a limit in the high pressure fueling system, but that would only really limit peak torque at this point.

[Arin@APR]

We haven't seen any weak components yet, so to speak. The car makes a lot of torque on the stock turbo, but it's easy to set a cap that still packs a punch and holds the torque for much longer with a larger turbo.

Fueling will become an issue on a big turbo with ethanol. We're working on a few items to help with that. :)

you think we will be seeing 500whp+ in the near future once turbo and fuel is sorted out? we all know the trans will hold it easily

[Arin@APR]

Would be great! :)

2019 SQ5

APR's 91 octane tune...<cough>stacked with a JB4 on map 2 running an E30 blend</cough>

Totally stock hardware except for an AWE intake...three tenth's faster than my best 0-60 than with the JB4 on the same E30 blend by itself, likely good for a 12.2-12.3 quarter mile rip based on the 12.5 I ran with the JB4.

The tune made a massive difference in daily driveability, throttle response and low end torque. 100% recommend, even by itself.

Hey Arin,
This upgrade work for the Q8's ECU?

[Arin@APR]

The Q8 has a slightly different engine as it's a MHEV. This is similar in the way that the RS5 and the S7 are slightly different due to the MHEV. It should be no problem once we get our hands on one.

Gotcha, would definitely be interested in the tune if y'all get it out for the Q8 ECU/Engine.

also what is the turn around time from shipping the ecu, getting it coded, and sending it back? I have an SQ5 on order and would love the power upgrade when it gets in

[Arin@APR]

Same day typically. Assume 1 day if it's critical.

[LMP1]

Anyone located in the Boston area we can unlock and flash your ECU same day!

[spindlewood]

Finally got off the fence. ECU sent to APR via UPS next day - says it will arrive by 10:30 AM tomorrow. Wohoo! And a shout out to Joe at XLR8 who was very gracious with my pestering and made the shipping label happen in time for me to get it out today. Great deal for free overnight both ways.

Thanks everyone for the encouragement. I don't have a Draggy and my JB4 is sold so I won't be a great source for hard numbers or pretty charts. Just another butt dyno. Mine will be a 91 tune. Hoping it will show obvious power increase. The JB4 in map 2 with 92 octane was so-so for me. Some of that might have been due to how I drive (don't / can't push it often), but everyone (including myself) has convinced me this will be different. If nothing else, the throttle lag should be improved.

And hey, according to Arin, my car is free to go 300 mph now with no limiter :)

[Arin@APR]

Very awesome. Thank you so much! And please post videos if you get it up to 300 MPH, haha

[chawski]

If you were to do a 91 tune, but end up running 93, is that a problem or just don’t see the 93 benefit? Around me, 91 and 93 seem to be pretty interchangeable for prmlemium fuel.

I ordered today as well. Bryan the form they have you put into the box with the ECU had a comment section. That's where I was told you need to state your desired AKI by APR customer service today.

Arin@APR I think you guys need to explain clearly in the form, or somewhere how/where customers need to express their desired AKI 91, 93 ect. Seems to be lacking for the ordering process.

Thanks, Surftek I thought the AKI tune you want is under "Program and features to Flash". Anyway I will fill up on the comments section. Still waiting for the shipping label from XLR8. Kind of late when I ordered.

I used XLR8 as well. There was a mixup with APR unfortunately. and it didn't get shipped back using Overnight Air (it was sent UPS 2nd day). I appreciate that APR was able to turn it around and get it out same day, but bummed that communication between them wasn't smooth. Not the end of the world, but was looking forward to get it back tomorrow.

Nope, mine is an earlier model without it and I've never used it. This 0-60 run had a 1.77 60', I went out the next night and cracked off a 12.50 @ 109.2 1/4 with a terrible, all wheels spinning launch and 1.86 60'...the 12.50 was my first try with the tune + JB4 and quickest so far (in +1500 worse DA than my previous best with only the JB4), so it's def a consistent 12.4 car with an even OK launch now.

Logs are super clean with a TON of fuel ceiling (I'm on an E35 blend now and you could easily run an E40 blend and still have more room in the trims than with just the JB4 on E20), and APR runs a much richer AFR than stock, so zero knock adaptation across any cylinder to keep things safe. It starts to pull timing at the end of 4th gear because IAT's are so high...so I've got an AWE IC on the way, and then I bet it's good for a consistent 12.2-3, will see what it does once it arrives and I install it!

https://youtu.be/NefdJdstVZk

As it sits, 0-90 from a stop with the tune + JB4 on map 2 and an E30 blend, just pressing the gas and going, it's WAY more explosive to 60 with the tune than it was with the JB4 by itself on map 5 and E30.

[subaruski]

Thanks for posting up a vid. Does the APR tune allow for free reving in neutral/park now?

I know you've done several mods via OBD11 and am curious as to whether the stage 1 flash from APR has changed, or reverted back to factory, any of your changes (i.e. seat belt chime, sound source volume levels, auto start/stop, etc. etc.). -thanks

[spindlewood]

Got the ECU back 3 hours ago. Went for a drive and did a couple of runs in my rural area. Nowhere to safely do a 0-60 so I basically do 5 - 70. I took a video (https://youtu.be/TSG_ZM7YRLE), but not sure what it is worth to anyone.

The few seconds of pull is nice and strong, but the SQ5 gets to 70 so quickly there is barely any time to enjoy it (nowhere near to take it higher). My wife says it definitely pulls harder than the JB4. I'm too absorbed in the drive to honestly notice.

You can see the Long Term Memory mpg dropping as I'm accelerating - goes from 29.7 to 29.1 in 5 seconds flat. Thirsty.[:p]

I'm pretty sure there won't be changes to custom settings. I will check though - it's a good idea. APR made start-stop default to off, so I may reset my custom climate control setting to see it in action.

I wanted to make sure this didn't leave a negative impression of either company. Stuff happen. Both APR and XLR8 were responsive and handled things without delay. In the process the overnight turned into 2 day. No big deal. Glad to have my ECU back.

I just got my ECU back this afternoon. Since I am all stock in the go fast department, this might be a more clear review of the stage 1 tune vs. stock sq. First thing I noticed after driving out the drive way is how much smoother the car is. Feels great.... really great! The additional power is definitely something you notice right away as well. On some hard launch's, you can feel getting pushed back in the seat more, proper difference over a stock launch. Car feels proper quick now, more of what I personally think an S car should be. The tune has met my expectations, (and dang what an easy process to do this mod). I think APR did a job well done for a stage 1. The butt dyno believes the 441 HP numbers claimed by APR. I'm on the 93 AKI btw. Curious if I can now pull ahead of my GF's stock S3. We will be finding out later tonight.

[bryan03tls]

Just got the tracking # from APR. They are sending back my ECU overnight shipping. Hopefully I get it tomorrow if not Monday. Can't wait for the extra power.[drive]
So I just install my ECU back then drive it? Or do I have to reset something.

[SurfTek]

Yes, just re-install and enjoy

[bryan03tls]

Thanks, install my ECU 30 mins. ago and drive around and the car pulls harder and drives smoother. Did not do a hard lunch cause my check engine light is on. Contact APR they said it's normal cause I unplugged the ECU. They said just clear the codes and I'm good to go.
What did you do to clear the code. Go to the dealer or unplugged the battery. Thanks

I did have the engine check light come on right after install. I ran a few errands. Got gas, car wash, car was turned off and on a few times during that time. The CEL turned off on its own. No dealer, messing with the battery. Should be the same for you hopefully.

Yup, if you don't have an OBD reader to clear them manually, they'll clear after 2-3 start/stop cycles and 15-30 miles driven one the ECU can show the fault condition doesn't exist anymore.

I knew it had a 12.3 @ 110 in it with the current setup, she rips! :) This is only my second ever attempt since adding the APR 91 tune, AND it was slightly uphill, and it was not my best launch. This is a 12.2 with a perfect launch - substantially better than the 12.5-12.6 it ran with only the JB4 on E30, I tried over a dozen times with just the JB4 and never ran quicker than a 12.5.

Mods: AWE intake, APR stage 1 91 octane tune + JB4 on map 2, car is running an E30 blend. Stock everything else; intercooler, cat, exhaust, no TCU software.

Thx! You can see I'm shifting around ~6250RPM every gear, seems to be the sweet spot. It runs a 12.7 if I just let it shift on its own in S, will be curious to see what a TCU tune does, lower (or adjustable) rev limit might be better.

You know it. Appreciate you guys turning it around quickly. Just hurry up and put out that intercooler for the SQ's.

I know it does, I've ripped a 1.74 best 60' and that's on my all-seasons, on a prepped track surface I bet it could do a 1.7 flat and maybe a 1.6x with summers. Any of them are good for a 12.2 with my current setup. I think it could do a 12.1 @ 110.5 exactly as it sits with an absolutely perfect launch on a prepped track surface, and that's all stock hardware except for the intake. Repeatable and easy will need an intercooler (which AWE is currently making for me) and maybe an E40 blend, time will tell!

[DiscoDan]

Still less than a week on the stage 1 tune, but this morning I was doing some more spirited driving and I'm now getting pops and crackles on the exhaust. I never got this on the factory ECU. In dynamic mode and manual shifting I could get 1 to 2 pops and crackles when down-shifting from 4 to 3, then 3 to 2. This is on the factory exhaust. I also noticed that up-shifts at high revs produce a more pronounced burble sound and less of a fart sound than before.

Anyone else getting the same behavior? I'm not complaining I'm really liking it.

[subaruski]

Mine seems to do this same thing with factory tune. Maybe more noticeable since I’m running AWE exhaust though.

Nice work man, that's legit! That intercooler and red star cat make all the difference to counter rising temps.

As it sits, the car rips consistent 4.1's (3.9 with rollout) without even trying, none of these were good launches (all 1.8's) and it's still super consistent, E30 blend, daily driver on map 2 + the APR 91 tune, still totally stock exhaust and intercooler.

https://i.imgur.com/p1YJp5Z.jpg

IAT's hit 145F by the end of 5th during 1/4 mile runs so it pulls timing but still rips consistent 12.3's, once my intercooler gets here it should consistently pull 12.2's. AWE said my intercooler is delayed until June 16th due to the pandemic and I'm being understanding, so it will get here eventually.

[4-ring-sleepers]

I have Forge FMIC and may get to 145 after 3-4 back to back runs. Usually stays around 90-120. Cat def makes a difference. I will try your shift point method and see if I can get lower before hybrid turbo goes on!

With your tune, is it possible to reverse the shifter from the gear lever? Instead of forward to up shift, make it so backwards upshifts, forward downshifts. Or would that be in the tcu tune?

[Arin@APR]

That would probably be handled by the TCU, but we've never looked into it on any platform.

[FFM]

Past vehicles that’s been corrected by merely depinning and switching the wires in the connector to the shifter. ISF guys do it all the time.

A little horsepower and a Crap ton of torque.....


+80 HP is pretty decent for just a tune

[vdubjetta02]

+80 HP is pretty decent for just a tune

I am on my 8th APR car.... I know the HP is decent, just way more impressed with the Torque specifically on this platform.

Just waiting for the day when I upgrade from my B8 SQ5 to the B9 SQ5.... not sure when I will take that plunge

*I want to modify a Q8, but APR hasn't been working on a tune for that car from my understanding.

When are we going to able to flash from the dealers? No one within 1 hour of me can do it without shipping out the ecu to be unlocked. 3-4 days without a car is tough.

Got my car back last night with 93 file. I have an intercooler on the car as well. Drove it home and went for another drive a little later at night. The torque on this thing is incredible! The car almost feels light for lack of a better explanation. It’s a different animal, I feel no need to floor the pedal it moves plenty quick at mid throttle. Super super happy with it. Just waiting on this back order intake to come in and I’m set ! Good job apr

Nice. What aftermarket intercooler are you running and what intake will you be putting on?

[eddiebarber]

I have the forge front mount and I’m waiting on the awe closed lid intake.

I went through this thread but couldn't find the answer - my apologies if this has already been answered:

Are there any warranty issues (with Audi) in getting this? I got a CPO 2018 SQ5 a few months ago and I don't want to void any warranties. Has anyone's dealership given them flack over this?

[subaruski]

You are 100% at risk for voiding your factory warranty.

Sure, it's somewhat dealership dependent but if for example you blow your engine, turbo, gearbox, ect I would highly suspect you'd get TD1 denied warranty coverage.

That's what I was thinking too. Just wasn't sure if anyone has dealt with a dealer yet post tune and got their car "blackballed" so to speak.

[FFM]

For that very reason is why I’m going to opt for a JB4 while I’m still under warranty. Will get the APR after it expires.

I prefer the ABT tuner, I had the JB4 but returned it after having issue after issue and I even made a thread about my experience. I'm waiting for Unitronic to come out with a flash so I can do it at home and return it back to stock when ever I want.

The dealer can still see if it was tuned even if you return it to stock fyi

[FFM]

Yup, plus it costs an extra grand for less power and we don’t have 93 octane on the west coast.

[eddiebarber]

Arin. Question, would there be any issue putting a downpipe on the car with the stage 1 tune? I just ordered a redstar downpipe and was hoping I wouldn’t run into any problems.

[Makes Centz]

Arin. Question, would there be any issue putting a downpipe on the car with the stage 1 tune? I just ordered a redstar downpipe and was hoping I wouldn’t run into any problems.

i have a catless dp with my stage 1 apr tune and no issues. Some people cry about having a check engine light but i know what its there for :)

[eddiebarber]

Thank you for the insight. When I chose the downpipe it gave me multiple cat options. I chose the 300cel that guarantees no CEL. So I’m assuming I shouldn’t have an issue. When I got the car I only wanted to tune it and leave it other wise stock. After stage 1 and a front mount, and a real good run in with a GLE AMG 63s, just made me think, hhmmmm, a downpipe would have closed that gap. And then it’s on to stage 2 lol. So I’ll be waiting for that!!!

[spindlewood]

Arin, I'm traveling to a high altutude area where 88 - 89 is usually the highest octane available. Is it safe to use 88 or 89 with the 91 tune in these situations? Is driving with a lower octane gas at altitude any different than at lower elevations in terms of potential pinging/damage?

Edit: If it is not good or safe to run the lower octane, would it help to add octane booster until returning?

https://www.amazon.com/dp/B000ARTZPE/ref=cm_sw_r_cp_apa_i_CkXiFbSP5SZM7

That's why this stuff exists, one full bottle to a tank will raise 89 to 91-92 octane. I did a bunch of before and after logging with this stuff back when I was running only the JB4 on 92 octane, effectively running about ~95 octane with this booster. It completely removed timing adaptation and gained 3 degrees of peak advance on map 3, and was safe enough to run map 4 in cool weather, couldn't do either on 92 by itself, logs looked terrible. Any of the octane boosters that actually work, like this one, will coat your plugs and cat over time, but one tank every now and then as needed is fine, the coating looks worse than it is. I ran it off and on for six months w/o issue and still keep a couple bottles in the back in case I'm ever stuck w/ a station out of premium (or the person I'm with decides to put 89 in the car because it was cheaper... sigh, haha)

[spindlewood]

Thanks. I've used Lucsd once in the past when I filled with 87 in a brain dead moment of old habit. What I'm really curious about is if altitude reduces the tune's need for octane or if an APR 91 tune means always a minimum of 91. I gather from your response the answer is 91 means 91. I know the stock tune can work with 87, but since⛽ octane offered at higher elevations is lowerer, i was hoping elevation somehow countered octane need.

It's not safe. 88 is terrible. 89 is not much better. Altitude "rules" from the past don't apply as the ECU adjusts for altitude.

If 89 is truly the only option, baby it. Use extra caution. Stay out of boost. If it knocks or hesitates under load, get out of it. I don't trust octane booster, other than say a little ethanol to help with octane, so long as you're not maxing trims.

Def not, not w/ modern high compression ratio forced induction engines. That idea has existed since everything about adjusting your cars AFR was a manual process, which was still the case for most vehicles even 20 years ago. As you gained elevation and the air thinned out, your AFR ran slightly rich compared to sea level, so you could get away w/ lower octane gas. Modern vehicles, especially the high compression ratio, direct injected, forced induction variety popular in high performance cars of the last decade or so, automatically adjust AFR and a number of other things as the environment changes (temp, humidity, elevation and hence air pressure, etc) This platform's ECU targets torque for total power output as well, so as you gain elevation, it will request more boost from the turbo to compensate and give you the same torque as at sea level.

All that to say you need at least 91, all the time, at altitude or not, and especially so w/ the tune that is pushing 91 to the limit. Like Arin said, if you stay out of boost (which is basically impossible in this car, you'd be driving below 2K RPM mostly) you can baby it in a pinch, but I wouldn't make it a habit, and I'd personally run octane booster any time I was stuck w/ a tank below 91.

[spindlewood]

Thanks for the replies. This is all the more reason to hope APR comes out soon with a device the user can OBD flash back to stock (hint hint). I'll carry a bottle of Lucas with me, but I should be able to time it so I don't have to fill up with anything less than 91. I love that my SQ5 has a range of over 500 miles with the mpg I get.

[Jettman78]

I just want to pass on a Kudos to APR on this tune. I’m coming off an ABT piggy back on my 2018 SQ5, I wanted something ASAP back in 2018 and I didn’t want to throw a TD1 flag ( never did BTW with the piggy back) . The piggy back was nice but it doesn’t even come close to the way the car drives now with the APR 93 tune. Full mod list includes AWE intercooler, carbon intake with lid, and touring exhaust.

[Arin@APR]

Jett, thank you for sharing your experience!

[Arin@APR]

As many of you now know, the factory intercooler is tiny and really robs performance, especially once tuned. Our popular S4/S5 intercooler is now designed to fit the SQ5. Get the details here:

[spoonieluv]

I have a 2019 S5 and I have a question abt the engine warranty if I tune with the stage 1 ECU. Would it be in my best interest to get the APR Plus for my vehicle?

[Arin@APR]

If you prioritize the warranty above all, that's the route to go.

[spoonieluv]

Thanks for your quick response...much appreciated!

So since I'm fairly new to the tuning game....does installation get included in the $1800 ecu tune? Also, would you recommend getting the plus on a new vehicle? Will the dealer void my warranty if they see that I got it tuned? And if they flash is back to stock...approximately how much is it to tune it back?

[Arin@APR]

The install is up to the shop. Some charge for their time, but some don't. We don't.

If it were me, I'd probably just go Stage 1 so I could use the 93 or E85 tune. In all my years of VW / Audi ownership, I really can't point to engine issues on a simple tune, so I've never worried about it much.

Tuned: Yeah, they can see it.

Flash back to stock: Free from us to get tuned again. Again, maybe labor from the shop.

[spoonieluv]

gotcha. I may think abt just the stage1 since I only use 93 oct anyway. Plus its cheaper! So in my area i have a VW dealer that shows up when I search for places that do the install. In your opinion....would you recommend a dealer do the install on for me to just go to a tune shop? Again...Im a newbie to this...lol

Would you say the intercooler is a must to get the full potential out of the tune? I put the tune on a few days ago and it feels strong.

[DiscoDan]

Would you say the intercooler is a must to get the full potential out of the tune? I put the tune on a few days ago and it feels strong.

The stock IC is the single weakest part of the entire setup, even with everything else stock. Adding a tune only exacerbates this. An aftermarket IC is a great upgrade.

[SurfTek]

The stock IC is the single weakest part of the entire setup, even with everything else stock. Adding a tune only exacerbates this. An aftermarket IC is a great upgrade.

I second this, also check out the detailed data APR has under their intercooler option for the B9. After seeing that data. I feel as though, with a tune, an aftermarket IC is no longer optional. I just added an IC and while it's hard to describe how it changed the car, it feels as though I just added balance/power that wasn't there before.

[Makes Centz]

You will feel a huge difference by getting a bigger intercooler even before getting a tune, thats how big of a deal it is.

Sounds like APR intercooler is next on the mod list. Thanks guys!

On my list as well, though I will go with the Forge unit solely because of the black finish. If APR made theirs in black I'd opt for that.

[MI_SQ5]

How is the fit on the Forge vs APR? I've heard good things about the APR unit.

[eddiebarber]

Hey sorry if this has sheen discussed but I havenÂ’t caught it. I switched to the e85 map yesterday. IÂ’ve been running the 93 map for a bit no issues. I noticed when I roll into the throttle, the car kind of picks up for an instant then hesitates then goes. I put it into second gear and opened up and close to redline the car hesitated for a split second then gets back to ripping as usual. Just very jerky and hesitant.

Has this been a thing ? Should I worry or what not? The car has a red star downpipe and front mount.

[Arin@APR]

How did you go about switching from 93 to ethanol? Did you drain the tank? Have you monitored ethanol content? Have you read our fuel guide:

https://www.goapr.com/support/fuel_guide/

[eddiebarber]

I don’t believe the place did all those things. Should I drive slowly through the entire tank of e85 and wait for the next fill up to get back on the throttle?

[chongl]

It's up to you to run your tank low and have the right gas for the map. Unless you're getting tuned, most shops won't be draining your tank for you

[eddiebarber]

I ran it down till I had 10miles left. Then drove it really easy after fill up for a day which could have been about 30-40 miles. That’s when I got into the throttle a bit. I’ve never gone e85. So hopefully after draining my first full tank it should help things smooth out.

[chongl]

Honestly, that sounds like it should be fine, although I wonder how much is in reserve even if it shows 0. That's the problem with having a needle versus these discrete blocks showing fuel level.

I used to have a WRX and had to run 91 for a longer trip, but I had some E85 jugs with me to swap over once I was within range of getting home. I ran it down to below the empty needle, and then some, before I pulled over and filled the tank with E85 and reflashed the ECU...had no issues

[eddiebarber]

Nice, glad nothing went wrong! Gives me a little reassurance. I’ll just granny it for the next couple hundred and get at it again. The car ripped so I’m super pumped to see how it feels!!

[Makes Centz]

Nice, glad nothing went wrong! Gives me a little reassurance. I’ll just granny it for the next couple hundred and get at it again. The car ripped so I’m super pumped to see how it feels!!

I would get a ethanol content sensor, sounds to me like you have shitty fuel. If you drove your car down to 10 miles and filled up with e85 and 40 miles later its still running like crap id say low grade e85 at your local pump. APR tune states e60-e85....im in Arizona and sometimes the crap we get is e53. You should not have to granny the car for a couple hundred miles.

good luck.

[Arin@APR]

I would granny it, and keep filling with more ethanol. If it's suddenly pulling back, it may be timing pull from knock retard. You don't want that happening.

[eddiebarber]

Thanks guys. I appreciate it. I will keep you guys posted after another tank or two. I’m just over half a tank now, gonna go full it up. I’ll keep my fingers crossed

[ssanderson1]

Arin, it's been a few months since anyone asked about the Stage 2 tune. Any updates on timeline of arrival? Also, if I pay for a Stage 1, and later upgrade to the Stage 2, is it more cost effective than just waiting for the Stage 2 to come out?

[Arin@APR]

We are not making a stage 2 tune. There are minimal gains, (single digits) with a downpipe installed, and it requires no tuning to make it work or to get the power.

[mercury26]

I had my APR intercooler and tune installed on my SQ5 this week. I agree with the previous assessments, this is how the car should have shipped from the factory. The intercooler looks impressive installed and excellent construction. Look forward to pushing the car with the new upgrades.

[Arin@APR]

Thank you!

[Arin@APR]

APR Plus is only available in the USA.

[6ixSpeedSQ5]

What is the reason for that? As a Canadian customer that is a pretty big deterrent to buying your tunes. It would seem simple enough to offer it to Canadian customers and a great way to get us to buy. I know I would personally purchase today if it were available. A great way to set yourself apart from the other tunes offered here.

Would love to hear your reasoning

Any plans to add it in the future? I can't imagine they are that different or that it would take too long to familiarize yourself with them. I'm sure it would easily make you the #1 tune in Canada if it were offered

[Arin@APR]

I'm sure it's possible sometime in the future.

[Short_Turn]

I'm curious if this tune still retains the ECU's flash counter like in other platforms. When my APR MK6 R blew a motor due to a faulty water pump, I flashed back to stock and everything was covered under warranty.

@Arin@APR :

Great news... being a 2021 owner.

Does the APR intercooler from the B9 fit the B9.5?

The only thing holding me back right now is tune switching. Can we buy the dongle and do our own tune switching with the new tune that has 2021 model support? Or is that still a trip to the APR dealer? There is a dealer in my town, so it's not the end of the world... but it would be nice if the tunes could be changed by me.

Is APR Plus still applicable if the APR intercooler is installed?

Thanks!

[Sturn992]

That's always possible. We don't have a way of knowing all of the factory codes. Typically there is only one with each new model year, per region, but sometimes more.

Did the dealer put in a request for your code? If so, our software team will let them know the next steps.

[Sturn992]

Yes they did, I will follow up with them this week.

[T0mt0m65]

Hey arin. I have 2018 sq5 with the ape stage 1 tune. After a few weeks with the tune I started getting intermittent message on the dash saying “coolant temp too high, let engine run with vehicle stationary” it would come on for a few seconds and turn off all the while the engine temp gauge stays in the middle. Have you heard of this? Will be having the apr intercooler installed very soon. Hoping this will fix the problem?

[Arin@APR]

I'd double check coolant levels if you're getting a coolant warning just driving on the street. Did you notice coolant temps rising beyond normal values?

[T0mt0m65]

I did check coolant levels and it was mid level b/t min and max. Temp gauge stayed in the mid range the whole time. Flashed it back to stock in the mean time while I wait for the apr intercooler I ordered to come in. Hoping I don’t see that msg ever again. 🤞

[barkles]

Is there any concern for us in California who have a Stage 1 APR tune in regards the new CAFE smog check requirements for tuned ECUs? Assuming I can re-flash to stock when the time comes, but not sure.

[Arin@APR]

We do not have CARB on this product yet.

[T0mt0m65]

Just FYI . Following up on my issue, after installing the APR intercooler and reflashing back to stage 1 tune have not had an issue with the coolant msg coming up. Comparing the stock intercooler with the APR one side by side it’s not a surprise, the stock one looks like a child’s toy compared to aftermarket, the APR is so much larger.

Arin, is APR going to do stage 2 or stage 3 for the b9 s4 platform? i was looking to go for the stage1 now that i know i dont need to send my ecu to USA but i dont see any path for stage2 or 3 on this with APR

[Hostile]

I’m pretty sure APR halted all stage 2 and 3 development due to the EPA regulations and enforcement.

[Arin@APR]

We have an upgraded tune in the works, and we also have a stage 3 turbo upgrade in the works as well.

Any timeframe on the stage 3 turbo release?

[Arin@APR]

Probably early next year to have final inventory built up, would be my guess.

[AnewMadrid]

Has their ever been an update for B9 2.0 Q5 tune? @apr

[Arin@APR]

V1.11 appears to be the latest for several ECUs. If you send me your VIN I can double check your version.

[cseaman]

Picking up our 2023 SQ5 this week. ETA for 2023 tunes?

[Arin@APR]

All we need is the factory file, if we don't have it already, and we can write software.
