Here they are....just don't add them yet, thanks.
Need another crack at it.

Either it would hang up and hit rev limiter on 2-3 shift if left to shift on its own. If I manually shift it through the gears , then in 4th gear the ignition would break up. Every pass yesterday one or the other would happen. I'll figure t out. Could be as simple as tightening up the gap. Misfires were always on cyls 5,6,7.

I followed the thread by AS6 for the meth install. http://www.audizine.com/forum/showth...?highlight=AS6

I'm trying out different rear tires than last time. Took me half the day to figure out what pressure they liked, and then pulled my best 60ft to date, 1.57. The trans wasn't happy at this point and refused to shift, which blew the run. I packed it in after that as I didn't want to damage anything.

I quoted my previous track times for comparison. You can see that I didn't improve from the meth...my 10.65 last year was identical to my 10.55's up until the 1000 ft mark...and the 10.59 mirrors the 10.59 I ran at Englishtown. Having only been to the track a few times, I don't have a lot of data to go off of, but I would say my car is not octane or IAT limited. The car has proven to be consistent though, at least when I can get off the line cleanly.

Last, the 10.554 was a hot lap run.

[DouglasW]

The quicker your 60ft, the slower the car will get as supported by your 1.57 pass. The reason is because the quicker your rate of acceleration out of the hole, the worse the 1->2 and/or 2->3 shift will be due to the shift algorithm in the TCU tune not being able to start the shift process early enough. By the time it figures out what's going on and that it needs to shift, it's already bouncing off the rev limiter killing the run.

Was your 1.57 pass using LC while the others were without it? LC invokes AMAX mode which will ignore certain inputs during the pass, such as attempting to manually shift early to avoid slamming the rev limiter.

Do you know if your car has the NSK or PKX trans? There should be a sticker in your spare tire trunk well which has this. The PKX has the improved mechatronic unit and beefier clutch pack.

It looks like running at track rentals has been working well for you. This makes sense since hot lapping is really the only way to make sure IATs are low enough to ensure timing isn't pulled. Once you head back into the staging lanes and park the car IATs will sky rocket. I'm sure you were driving up and down Jackson Rd in between passes too.

Awesome runs BK! Agreed the meth was not the reason for your slightly improved ET compared to your non-meth passes. Given the hot lap time, seems like it's working well for cooling! Congrats on the new record!

[DouglasW]

Why is his car so much faster than yours especially when you have the bigger inlets and killer cold air setup? He's trapping 132 consistently. Weren't most of your runs in the 127-128 range? That's an enormous difference especially when you should be making more power with those expensive parts.

you say crap you know is wrong just to try and get a rise don't you...? Mickey trapped 129 on his 10.69 which I'm sure you well know - 2ish mph isn't exactly conclusive of anything considering that was his first and only track outing with stage 3 and Atco is known as a fast track - my traps can vary that much in a given day. Always interesting you seem to know how to point to and fix everyone else's issues but your own. That said, welcome back, things were getting stale here without your condescension...

I’m thinking it’s my paint color or PPF, testing to follow.

Your trans still broken?

Trapped 129+ 4 out of 11 runs. 90+ degrees majority of the day. Not mad

We’ve all seen the bitterness from the guy whose car spends more time broken in his garage than racing. Also has more track visits than all of us combined and still can’t post close to a record. Bitterness nearly justified I guess.

Seems to know all the answers but can’t make his own car go any quicker, even with those 1.4x 60’ times. The mystery continues.

Thank You and much appreciated.

I'll just ignore the rest. However, just for clarification...by hotlap I mean I ran my car for a full pass all out, then drove right around back into the lanes without any cooldown and ran it again....hence a Hot Lap! The other 10.55, I drove straight from my parking spot in the the pits into the staging lanes and ran my car just like anyone else would. Talk about not seeing the forest for the trees.

I’m en route to Greece for 10 days and when I return my car should have all the same parts + AMAX. I plan to track it July 5th. Stand by.

The credit goes to Eurocharged Canada, SRM simply provided some hardware.

As Heel mentioned, he'll go 9s once Amax issue is remedied

Hey guys, here's a video from my last track day, and an overview of the car immediately following my second 10.55

No launch control, just a flat punch from idle to about 75% throttle, then roll into 100% about one car length off the line. Full weight, street tires, and I believe the DA was ~1100 at this time of the day. This same launch technique landed me a 1.57 later in the day as I got my air pressure dialed in.

Warning: Video is long, 5 minutes, as I covered as much as I could about my car.

Love the video lol, it’s good to know what mods actually make a difference.
The upgraded HX really shines when hot lapping.

I just switched to APR tuning and had a question for everyone here in context of S7/S6 4.0TT. What launch RPM has proven to provide fastest 0-60?

Too many variables to give a black and white answer. Track prep, DA, tires, suspension setup, stage tune, etc.

If stage 1, majority have found most success launching at 5k if prep is decent or better

That's good news, I assumed 5k and had it set there when we installed. Thanks for the advice!

All 3 runs, RT lane....

IMG_20180708_005730_160.jpeg

[Ghost2112]

The first run was racing a built Alpha 12 GTR...
I redlighted and it still crushed me..

Next run I ran a 10.9 in dynamic mode.... I ran my first run using my individual setting with my suspension in auto. I don't remember what I ran against on my 2nd run because my task was to finally crack why my car runs weird times. It's Dynamic mode... On my suspension its just best to leave it in auto mode and let it handle itself....

Excellent engineering there.... Good job Audi!!!


My last run was against my buddies Demon. To his testament, it got colder and with his car being on slicks and skinnies he couldn't get it to hook up. He was hopping all over the place...

The very last run the track manager takes it out. Runs a 10.90 in it. I wanted to run but I needed to get home. Next race will be against his MB AMG GTR. I'll def. get more pics and video of all of this.

Went to a midnight track event last night and finally had a chance to run my car with the Sunoco 104oct fuel. Outside temps were unusually cold (60s) for this time of year making traction on a cold track the biggest issue. My best run of the night time slip attached. You can certainly tell a major difference with and without AMAX!! Really hope to see an updated APR ECU and ZF tune at some point. Going to look into the inlets now and continue to follow SRM and Eurocode’s work. Some GTX30 billet turbos with better cooling would be nice.

Thanks! I had run a few times before this run so car was not cooled down for this one and my 60ft isn't the best I have been able to do. I think if I would have gone to the test and tune earlier in the day while the track was hotter, I could have hit a 10.3xx I didn't engage AMAX on most of the runs, I was trying some different techniques since I was spinning the tires too much. Now I am wondering if I should pick up some 20" wheels and run a taller side wall and a stickier tire, or at least run something on the rear with a smaller wheel/tire combo for track runs.

1st of congrats, that's a good pass

Outside temps were unusually cold (60s) for this time of year making traction on a cold track the biggest issue. You can certainly tell a major difference with and without AMAX!!

looks like upper 60's which shouldn't normally be an issue for traction and your 1.61 60'/4.419 330 and 106mph 1/8th seem to indicate you were planted pretty well. Amax is massive, generally .3-.5 sec.

Really hope to see an updated APR ECU and ZF tune at some point.

just curious what you're hoping for from a TCU file, I've done a lot of investigating and there's no evidence I can find that a TCU file will do anything to make our cars faster from a straight line standpoint. And for those hoping AMAX can be engaged from a roll, it can't, APR and EC have ruled that out.

SRM Sean (among others) is doing great work in coming up with solutions to our issues, mainly because he's an owner as well as a fab guy. The biggest improvements needed, as you alluded to, are in the cooling, and the bigger hybrids for sure cause a lot more heat. I'd be inclined to look at the stage 1 cooling upgrade he's got first, it's a solution I been privy to some inside information about and it works, even on a stock turbo car. The GT28/30 upgrade I think will need some more time to prove itself and I for one am living vicariously through my buddy who's proving the GT28's work, but regrettably he snapped and axle a couple weeks ago so with the extra power comes consequences. There is as much movement in the platform now as I've ever seen so it's an exciting time to be a S/RS 4.0TT owner.

Thnx! I think a little less wheel spin and I would have had a 1.5 60ft and closer to a 10.3xx.

Looking for 3 things from a TCU tune:

1. I want to keep AMAX
2. I would like to see a bump in the rev limiter
3. I would like to see TQ management and shift points match the ECU tune and/or other mods

I have been talking to Sean and strongly looking at the Stage I cooling and the intake tubes. The upgraded turbos are on the list to consider, but I really want to see some additional results and make sure I have access to a somewhat local and proven tuning option. For now, I would like to maximize what I can out of the stock turbos. Honestly, going 9 sec while cool as hell, would cause issues with ongoing track events as I would need a roll cage, hehe The axles breaking is a concern even at current power levels from my understanding.

Hofahome, these runs were on 104 plus methanol...no improvement over 104 alone. On the street I'm running 100 octane racegas file on pump/E85 mix with meth, my datalogs are perfectly clean. Next track visit will be on the latter...just the way she is everyday on the street.

Nice run IowaRS7...106 in the 1/8th is flying!
