Cobb doesn't affect the force feedback on the accelerator pedal(I'm not even sure if they can even access that, or if it has any type of electronic adjustment. It may just be a spring providing the feedback/resistance) and the same goes for braking(it's not brake by wire so there's not much a software change can influence.)

Can someone give a little feedback on my stg 2 logs. Power delivery just doesn't feel right. Sometimes there is a hesitation when going full throttle (not spool). Also partially (50% or so) in 6th gear on the highway can sometimes result in a pretty violent shudder.
Going to try the sport tune. And send logs to Cobb. Sorry i do not have more a more concrete description of the cars behavior. |

you have some Throttle closure for overshoot at around 3500 rpm that can be toned down with ATR or a custom map (PTF for example) . I guess you had TC off right?
Also 1 log shows timings drops on all cylinders while the other one was ok. Pull the car to redline as well not only 6400 rpm.

Once the FMIC goes in its going out for custom tune to try and smooth it out. Does the tune look on the safe side to you? Just wish it was more consistent from one run to the next. thanks for the help! |

Same with other gears, 3rd gear can be the difference between pulling hard, and pulling so-so. Going to look into the ATR, not overly familiar with any of that. Links appreciated if you know them off the top of your head. Off to the search button, thanks! |

Your "ECU" designation is actually your ROM revision.

that's why its a good idea to uninstall your COBB on Dealer visits.

If you got 3.38* on 3 or less cyl. (Guide line) For timing corrections you are in good shape. As well as no throttle closures, TPS, should be 80.98, on WOT, any dips typically means overboost on OTS MAPs. Or you had traction control on. That is a good guideline, I'll check tomorrow. I wouldn't worry too bad if it not ideal, let's check.first. COBB is pretty good as long as you met the.requirements.
