Thanks

hey guys,

i know it sucks, but it can be done. Practice feeling the kickdown. The best I have done was WOT at 3800 RPM.

But if you do this, your worries go away.

Thanks

Paddle or the manual shifter will work. Just put it in M3.

DSC, you have to hold down the DTC until you get the big triangle with a circle around it. Just a few seconds.

Be sure to have a safe stretch of road, flat. With stabilization and traction off, you must be careful., you'll reach close to 100 mph 3rd gear redline (about 90 in sport I think). But it only takes about 9 sec.

so looking at the logs, is stage 1 drive and sport pushing 14psi? i thought sport was more power?

Sport i believe ~14 psi tapers down to ~11 psi is the target... I have never ran Drive so I am not sure.

S1 Agg. is ~15 - ~11, I have got into the ~16 psi range on some logs.

S1+ Agg. ~17 - ~11, with some peaks at 18.5

Also, take a look at your timing, your timing will be higher in Sport than Drive. and no timing corrections.

335twins · 11-20-2012, 04:28 PM

interesting, at one point i hit 16psi on drive map, i hope that's normal.

well it wont hurt. I do know the v401 MAPs are more aggressive than the v300 MAPs. You may also be getting throttle closures due to "over boost" which I can't tell until we get some better logs. If so its an easy fix with ATR, as reported with other users...

FYI, I hit ~19 psi mid range with my stock turbo's.

PTF Pro Tune FTW!

overall not too bad. It appears some throttle closures when you hit ~16 psi. (log 17) Try to get better, clean logs so we can look again. Timing corrections are not bad as well.

Try that pedal spacer, it will make logging a much more, exciting experience.

No problem bro.

How do you guys deal with the O2 cel light as I am about to install Cobb today.
Does it matter if I drive around with the cel for a while also ?

You're fine to drive around with cat ineffeciency codes until you can get the AP installed. Once the AP is installed any of the OTS stage 2 or stage 2+ maps will get rid of the CEL. Using ATR you can also disable the OBD2 readyness checks for any of the maps if you want.

If you want, I'll be down in the Philly area Tuesday (11/27) & can help you take some logs, show you what to read & what to look out for.

Sounds good but I have some work on Tuesday but maybe late afternoon or any other day in the afternoon. I'll still buy the beer.

I'm gonna be getting dyno'd in afternoon @ Undercover Performance (~1/2 hr from Philly) & will be in South Jersey for a good portion of the day. If you're interested send me a PM and maybe we can figure something out
