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.
Here you go:

These are the raw dyno graphs (93 and 100). We used 93 for stock. 6 runs chipped, 6 runs stock.

Lol damn that transmission, my car on K04s ran a 9.47 60-130 on E85 And I had the hardest time busting into the 11s hahaha I need to have Scotty make me a dog box… Or something.
Scott? Ask for your brothers old Scott rebuild job. It held up for about five minutes.
That wasn’t Scott’s rebuild, that was David Chang’s. synchros were sourced from scott if IIRC but it wasn’t even a full synchro kit.
Incredible. Thanks.
So Arin…will this engine fit in my bay!!!
