This is when he did it… 4pm wednesday
So about 4000 feet different

The video above was 9.9 vs 12.1 with a full tank of gas. I’ve seen as low as 9.2 during testing. I’ll have to get back out there with everything in the production state to see what I can get. 
Yesterday I went from 3.6 vs 4.1 (again full tank). I haven’t tried quarter mile. I never really do that on the pbox.
I’m going to see if we can hit the drag strip this weekend. Rain is scheduled though.
Personally I’d like to go down with 93, get stock and chipped and then drain the tank and run race fuel but we’re out of race gas right now and not scheduled for more barrels till next week.
I would suggest two seperate trips. First one to get stock numbers. Second one the following week to get modified numbers
Or just skip stock altogether. Only problem with that is you’re going to be measured against what the magazines come up with and with that S6 already tripping off 12.1 @ 115, that’s a tough benchmark.
Make sure your car is running well and tuned for 93 for a few days of driving before you go, and try to make a commitment to make 7-8 passes over the course of a few hours.
I personally think you sold the RS5 APR stage 1 times short a little by doing 4 passes in such a short period, and flipping over to tuned half way through. You also ran a VERY hot car, having just driven there. It results in an ‘underpromise/overdeliver’ marketing philosophy really (contrary to most Audi tuners lol) so that’s good but I really think that on a cool day with good DA, and a nicely adapted 93 tuned RS5 with only 1/8 tank and no crap in the trunk (spare, tools etc) that car could run 12.0 and heaven forbid maybe 11.999.
Same goes for the S7…make sure you get everything you can out of it when you go.
Personally I’m interested to see what my results would be back to back, same track, same car, same fuel, same driver, same weight (except for variances in fuel level), same factory options, same tires, same weather for the most part, same everything essentially.
Quite a bit of the “adaptation” stuff is misunderstood in my opinion. Ignition is reset every time the ignition is cycled. We can keep fuel trims and other variables related to each vehicles small differences the same during program switching by not clearing them. For the results on the dyno we typically do 6 pulls stock with enough cool down and reving between to keep fresh air pulling through the motor until starting IAT’s fall back to nearly where they were on the run before. Then we reflash right on the dyno, and do the 6 pulls modified. The difference is always night and day and doesn’t require lengthy adaptation periods I guess unless something is really really off from the factory.
Yeah, I can see that if I’m after absolute records. It would be tough though. It’s a long drive to the track and it’s only open for about 5 hours. But overall, I’m not so sure I’m worried about it yet. The car was really consistent even though it was on the dyno all day. For example, on 93, run 2, 3, 4, 5 and run 6 were nearly identical towards redline. Run 1 was the only variance (couple HP less than the other runs) and was that way stock too. I can swap fuels or program modes and try to get a couple passes in.
Good stuff Arin… looking forward to the results… Does the adaptation logic apply to the S4 tune as well? I always wondered if the lengthy adaptation mattered and how much… Not that I switch fuels too often and if I do it’s GT260 to Ultra URT… lol
No comment on the DSG tune, eh 
lol he skipped that one
What’s wrong with DSG…you just want a more effective launch?
[quote=“sakimano,post:25,topic:4097”]
My DSG works probably better than most from the vids I have seen, it shifts at 7K, gets off the line ok, and doesn’t misshift often… My biggest need would be the extra 200RPM’s per gear thus allowing me to trap in the low 120’s before needing to shift to 5th gear, which should help my 1/4 mile times especially when stage III… Sure I would like LC and faster shifts but my biggest need/want is the additional RPM’s… I would pay for that alone…
Where do you shift? On the RS4 and the manual B8 S4 I believe 4th gear gets to about 129 MPH (actual, not speedo MPH which reads higher). You’re shifting into 5th in the dsg at around 115? (I don’t know what the 7 gears are spaced out like)
116-117 from 4th to 5th according to the speedo… It’s probably 115-116 though, it varies slightly based on RPM’s that the actual shift occurs at which based on quite a few logs is 6900-7000K… I guess I could calculate it, but I am in the office and can’t remember if I am running 245 35 or 40’s which effects the tire diameter slightly… 35’s are 25.8 and the 40’s are 26.7 diameter… Here are the DSG ratios(B8 as the B8.5’s are worse IMO)
S-Tronic:
1st: 3.69
2nd: 2.24
3rd: 1.56
4th: 1.18
5th: 0.92
6th: 0.75
7th: 0.62
Final: 3.88
Here is the manual just for reference…
Manual:
1st: 3.667
2nd: 2.158
3rd: 1.52
4th: 1.133
5th: 0.919
6th: 0.778
Final: 3.68
I just played with some #'s… I think I have the 35’s as it would be about 117 from 4th to 5th and the 40’s would be about 120 from 4th to 5th… With another 200 rpm’s per gear the 35’s would be about 121 and the 40’s about 125… I guess I could swap tires as well but mine are nearly new… sigh…
Yeah, pretty much. You really shouldn’t see power increasing with adaptation. Not saying it’s not possible, but it really shouldn’t happen I guess unless something is majorly wrong but the car should be essentially adapted quickly after clearing all adaptation and going for a drive.
It takes just under 6 degrees of ignition advance being pulled to begin any knock adaptation but over time if the fuel quality increases, and timing is not being pulled, it will go back to where it should be.
SilentBob mentioned the same stuff here:
As for DSG, we haven’t looked into it on the S4 yet.
Arin can you talk more about the manually part. These turbos don’t have a waste gate… is that what your saying how are they different. Sounds cool I would love to know more
Tuning them is quite different. There’s no “N75” duty cycle to look at, it’s controlled differently. During part of the tuning process we wanted to verify when we were asking for 100% and thought we were getting 100% that we were actually getting 100%. We manually wired them shut… Needless to say, it makes quite a bit of torque at 100%. ;D ;D
My fastest run was @-1850 DA. I haven’t done a new run with -3000 DA yet. Will get to it soon. Want to test the shift fix they applied to v2.2 as well as 104 tune.
So 2850 feet difference. In other words pretty dramatic.
Oh no question about that. I’ll try and get some -3000 insane DA times like Paul and Richi had, one night this week or next if possible.
Bummer. We planned to hit the strip but rain was in the forecast so brunch as the Baas’ instead. Maybe next weekend. We shall see.
Arin, show some love and share the dyno #'s you posted on FB. Th number are incredibly impressive. The delta from stock to tuned only on 100 is insane.
The stock numbers are insane based on what Audi claimed the crank numbers are. Hugely underated.
