11.884 at 114mph - B8.5 S4 DSG with Unitronic Stage II+ and Injen intake on 93 octane

[bhvrdr]

I made it to the track tonight since it is getting nice and chilly out. It was an absolute MAD HOUSE there. There were about as many cars on slicks as on street tires...a lot of cars with parachutes, lol. Add to it there were all kinds of 2wd people having traction issues resulting in a couple accidents not to mention people snapping axles. In three and a half hours I was able to get two runs in.

Conditions:
21ft
53F
30.25inHg
66%RH

-625 DA

The first one just didnt feel right for the launch. I hit the launch control limiter and ended up releasing the brake on the downswing. The car was a bit heat soaked as well since I got there early as the track opened and the car was still hot.


The second launch was so much better. It caught on the upswing from about 2000rpm swinging up and I got just a tad bit of wheel spin (no bog at all). The car had also been sitting cool for 2.5 hours.


The car remains the same...

-Unitronic Stage II+ 93 octane tune with AWE 57.55mm pulley

-93 octane shell

-Stock DSG

-Injen Intake with heat shield removed

-19" TSW Bathurst with 255/35 PSS

-Stock cooling and exhaust

-Full weight minus the spare


Best time was 11.884 at 114.26mph





I'm thinking of doing some dual pulley testing in the next 60 days. Moving homes has been taking a lot of my time up right now or i'd say sooner...who knows. When I get restless I may just go out and throw the crank pulley on but my garage is stacked with boxes right now :)

Nice. Does Unitronic not have a dsg tune? I've been debating going Unitronic for a few weeks now because of the advantages of flashing from home, but haven't seen a lot of people running their tune

No they don't as far as I know and I don't know when they will. Bummer

Gr8 times Mike! Thats a fast time for 93 octane and without a DSG file; in fact it may be the quickest 93 octane run?

That negative DA is why ill be going out tomorrow for test -n-tune; can't wait!

[DBL R]

Not to derail this thread, great time by the way, but why did you go with the injen intake?/also remove the heat shield?

[jran76]

Nice runs in great conditions on a fast track. I think you'd be hard pressed to squeeze more out of it with the current setup. That's pretty quick. Did you log by chance?

[jokingjimmy]

Grats man! Nice run!

[TexasDfwS4]

Their you go again, making headlines for Unitronic. For the person that wants to tune from home, you can't beat it.

Thanks! Yup, awesome conditions. I think you'll do really well. Good luck today!

Not to derail this thread, great time by the way, but why did you go with the injen intake?/also remove the heat shield?

I went with the intake because it is the largest intake tube on the market and has a great quality filter (made by Amsoil) on it and also has a nice little bracket that supposedly keeps it from rubbing, etc. The design seemed good enough. Nothing overly special. I bought the CTS Turbo intake and have one at the house too. I removed the heat shield purely because I wanted to hear the SC whine. Its juvenile but I love it, lol.

Thanks. Conditions were great. I'm not sure about the whole fast track thing but it was definitely fast conditions on a track at sea level so i can see why one would say that. You will see some incredible times out of PBIR during 3 months a year (as you will at many sea level tracks). During the summer time (which is 8 months long here, lol) you'll see some not so good times as it is always over 80 degrees with over 80% humidity. To give an example, my car runs stock at this track during the summer about 13.2 at 103mph. That is definitely not a fast time. I have no doubt it would run a 12.8 or maybe 12.7 at 105 or maybe 106mph with no other changes except being in the winter time here...a great time.

I went from a 12.4 to a 12.1 just going from a summer 80+ degree day to a winter 60 degree day making no other changes to the car. I probably could be running a 12.0 or even an 11.9 with the CW stage 2 had I run with that last night too so that would have been going from a 12.4 to an 11.9 making no changes to the car at all except conditions.

I didnt log while doing the runs. I still get a bit flustered staging/running. I really screwed up last week when I forgot to even put the transmission in Sport mode. What a difference that makes. I log the car somewhat regularly so I dont expect I would have learned all too much.

Grats man! Nice run!

Thanks Jimmy!

I'm pleased with the ECU tune so far. I really cant offer them many suggestions for improvement in that respect. I'd like to see them have a DSG tune, though.

Great times!

[waxxonMTL]

I believe the fastest 93 octane is giac at 11,6 right ? well.. i bet if you add dsg tune + LW rotor + exhaust ( 5-10whp is still better than none lol!), you would've gone 11,6 or maybe even 11,5 !

Thanks jsh.


waxxon, Yeah, I tend to agree with Jran above that the car is pretty maxed when it comes to the ECU tune most likely. If this car had more mods like you listed i'm sure it would have been capable of breaking a record last night as the conditions were definitely record breaking conditions. We'll see how long I can wait before going elsewhere for a TCU tune :)

Mike

[waxxonMTL]

as i can see, you have 3 options really ;

1. tcu tune
2. try double pulley
3. water/meth ( to reduce heat soak at the same time)

I totally agree although i'd like to change the number 3 to some more daily driver friendly heat mitigation techniques. I'd like to test each of these things independently to see how each helps/hurts. I'm just not sure what is next. I think it may be the dual pulley because I have it at the house.

Mike

[jran76]

A stock S4 ran a 12.6 there which is easily the fastest stock time (0.25 seconds faster than the next fastest stock DSG car). I'm not knocking your time, but PBIR is known as a fast track in good conditions. You can say that about a lot of tracks like ATCO too. Being at sea level makes a big difference. Starting at 600-700 feet like we do here, or 1200 feet like Thompson makes a big impact.

The Uni tune seems to be working well. If they don't release a DSG tune soon, why don't you try out something like the 034?

Edit: I re-read your response on the fast track thing (sorry just skimmed through on my phone earlier), and I think we're saying the same thing here.... The point is, sea level plus good conditions equals good times. No doubt heat or crappy conditions is the enemy of fast times on these cars (and most).

Right on. I hear you.

I'd like to learn more about the 034 stuff. I just dont know much about it. I am thinking GIAC possibly as well (as it may mate well to the dual pulley too). I'm trying to go with a TCU tune that isnt going to give me issues and so far people have reported shift hang ups with several companies and LC problems with a couple companies. The GIAC tune doesnt seem to have many issues reported at all although that could just be people being quiet. Tough call for me. If you know anything about 034 id love to hear about it.

[BlownOne]

Nice run!!! Jran is right, there are just some tracks that the same setup will run .2 faster for whatever reason...I believe atco is downhill iirc. Not knocking your run brotha...your car is moving out!🏎💨

Some tcu tunes are having issues with shift hang ups and launch control? Can you elaborate?

Will

[ronbars]

I think I saw your car there last night, unless there was more than 1 S4 out. I wanted to say hello, but didn't know who the owner was. I was there with my silver S6 and my friend's red A3. The weather was PERFECT, that's for sure. Aside from the accidents and the breakages, a good time!

I'm not suggesting this is a widespread or even a major issue but I'd like to learn more about those issues so I dont end up encountering them. Perhaps it is only certain years or certain combinations of conditions or mods. I dont know. Id like to learn more though so I can make an educated decision about which TCU tune to go with.

Hello there! Thanks for chiming in. Yeah, I saw your cars there. Do you have a tune on your S6? What were you running. I thought I saw mid to low 11s but wasnt sure. That A3 was running like mid 12s right? I believe he filled with race fuel. Stage 2 Im guessing? Nice cars and, yeah, great conditions. What a mess as far as getting runs in though.

I'm running APR Stage 1 software. I put 3 gallons of 100 octane GT 260 in the car when I got there as it said I had 0 miles left, but I ran it on the 93 octane map since it wasn't truly empty of the 93. Best of the night was 11.539 @ 119.35. My buddy's A3 is also APR Stage 1 with an APR intake, his best of the night was 12.677 @ 108.37. He's only got a 93 map and I don't think he put any 100 in the tank, but I'm not 100% sure about that.

Those crashes sucked.. two nice cars getting bashed like that hurts. Glad the drivers were OK, though.

Hi Mike,

A DSG tune should do a lot for your times, and I'd be happy to answer any questions you have about ours. The reason we haven't posted much info yet is that the software hasn't officially been released, and we don't quite have all box codes and software versions finished yet. I've posted a brief list of features below.

034Motorsport DL501 Performance DSG Software

• Increased Shift Speed + Optimized Shift Points in Drive & Sport Mode
• Manual Mode Auto Downshift Disabled
• Raised RPM Limit for Use with Stage 1/2 Performance Software
• User-Selectable 4-Step Launch Control - (3,000 RPM, 3,500 RPM, 4,500 RPM, 5,000 RPM)
• Raised Launch Control Counter Limit
• Flashed Directly Via the Factory OBD-II Port

Thanks for posting those times man. Its fun to compare. That is a nice trap speed there. I saw the A3 at the track pump when we got there but he could have been just parked or whatever. Sorry I didnt get a chance to say hello. I'm thinking about an A8 or S6 in the future, it is nice to see how well they respond to a simple tune. Maybe we'll see each other again.

Wow, thanks so much for taking the time to post. I'll have to give you a call to talk more. I wonder if you would make your tune available to someone to flash at home if that person has a lot of experience self flashing (I flash my track car files all the time). I look forward to learning more about your ECU and TCU tunes as you all continue to bring about new products and wish you guys great success!

[jran76]

My understanding is the APR DSG issue is more of an issue with it working in conjunction with their ECU tune. Something with the shift RPM's on each side. The fact andthen (Tom) saw the same slight hangup that I see, and it completely went away when he changed to the EPL ECU tunes backs this up.

So, in theory, it should be an easy fix. With that said, I know they've tried a few things on someone else's car and the problem was not resolved, and they seem to be taking their own sweet ass time fixing it at this point.... I'd probably consider it a minor issue with the exception that they are charging a hefty premium over any other DSG tune to the point you'd expect a premium product/support. With all that said, I do feel like it will be the best product on the market if they can fix that one issue. The features they have, and AMAX, are pretty awesome.

The GIAC tune obviously does just fine, and everything I've seen from 034 so far looks good. Obviously with 034 I like the fact that they are more open to running it with stock/other tunes.

care to explain what's the added *useful* feature of the APR Vs. all the other tunes ? I only see AMAX and yet do not clearly understand what it does or how it enhance the performance of the car.

Fact that you can remove downshift or upshift in manual mode is not what i call something useful, more of a preference gadget than anything else.

P.S: I'm partial to any tuner as of today, still learning how every different tuner differ from each others.. so far I must say, I have very good faith in 034's offering when it will be available. IMO, APR/GIAC opened the way, Unitronic came with flash at home, then EPL saw the need for flash at home + the lacking DSG tune so he filled that gap. Hence why I have hope that 034 will come up with everything else the others have previously offered + more OR AT LEAST, better customer support than what we are seeing right now. ( EPL is over-busy, APR doesn't really care, no update from GiAC for over a year, nothing for over a year form unitronic about their tune)

OOPSSS sorry for that off-topic !!

Unitronic has update their tune in the last month or so. I was the first in the states to get the Unitronic and was part of the learning curve, but after I reflashed it is wonderful.

Here is a good description from Sean@APR on what the AMAX mode does:
Amax uses both clutches simultaneously and slips between the gears. A normal shift de-rates the engine by telling the ECU to pull timing. It does this to prevent free-revving and to lower the torque at the clutch to make shifting easier. It has the engine de-rate while it's opening the first clutch. The engine free-wheels for 50ms or so while the second one is being closed and then the TCU tells the engine to bring back the power. That de-rate timing retard is what causes the DSG "farts" you can hear on videos.

Amax doesn't work like that. When in this mode, the TCU keeps the beans on the entire time. There is no de-rate at all. It controls the engine RPM by having both clutches engaged in the linear (slip) region together while it transitions between the two. The upshot of this is that there is no de-rate, the engine is making full power the entire time and is transmitting it to the ground even during the shift.

The APR DSG tune also has:
- 3 different launch control RPM's, and you can choose those 3 values. No one else has this. 034 will have something similar.
- Increased LC limit from the stock 200 to 3000. EPL and GIAC both top out at the stock 200 as far as I know. 034 said they have increased theirs. I don't know about Revo.
- Greatly reduced "clunks" in lower gears/speeds. APR is great in this regard and definitely better than a couple of the others I have been in.

Overall, nothing completely earth shattering, but being able to turn of/off the automatic up/down shift options combined with the four other features I listed give it a nice set of features. Also, let me be clear, the only issue I am having is a very very minor issue. It has a very minimal effect on performance. I know some of the 2010 cars had some other issues, but at least on 2011 and newer cars this seems like the extent of the problems.

Thank you! I wonder this too :)

No idea other than to say my feedback from Uni has been that they are focusing on getting the off the shelf tuning needs of their customers done before venturing into any custom or new projects like this. I am not convinced this will be any priority. I'm not saying thats a bad business philosophy but it is a bummer for me, haha.

Thanks for taking the time to provide more clarification on the TCU tune Jran. Its good knowing that the hangup is only having a relatively minimal impact.

The thing that struck me instantly about your post, though, is what I quoted above. Are you sure EPL or GIAC do not raise the factory LC usage limit? That would be a total deal breaker. Every time you do even the "mash and go" technique it triggers the launch counter and I actually like playing with it on more deserted roads. My son thinks its fun as heck, lol. I can see my 200 going by really quickly. That is ridiculous is they dont up the limit. Can anyone confirm this? Thanks,
Mike

I am 100% sure on EPL. That's why andthen is still using the APR DSG tune. Tony is planning on addressing it, but he hasn't had time yet. You can look at Jones' post on here about hitting the limit with the GIAC tune. Maybe that has changed since then. I'm not sure....

http://www.audizine.com/forum/showth...ighlight=Limit

[Loe]

GIAC raises the LC limiter to beyond reachable levels now. Im getting the update flashed soon.

[bhvrdr]

^^^^^ Thanks both of you guys. That is good information to know. I guess I had always just taken it for granted that the usage limiter was raised on them all. Hopefully they all will have it addressed soon then. Yeah, that would be a deal breaker.
