I also have a manual.
When you are data logging boost, look at the psi when you are in gear. My guess is that you won't see anything higher than 14 to 15. The boost will jump when you are at WOT and then shift. |

Most likely a shift spike as others have suggested. You can always confirm this by enabling data logging for a few pulls then reviewing the data on your computer. A data logging tutorial can be found @ http://accessecu.com/cobbtuningweb/p...o/datalog.html.

I'm on the fence about this. Realistically what kinds of power differences are we looking at between JB+, JB4 and AP on a completely stock car? I can look at dynos all day, but they seem to be all over the place.

I am on the fence between the Cobb AP and a JB4. Does anyone have some track times and slips on the Cobb?

thx Maxnix. Found one example on the e90 and it was not in the 'all Cobb tuning...' thread (43 pages later). It did show almost a 1 sec better 1/4 mile time than stock on the e90. Still looking for a couple of 135i slips (perferable with the 6MT).

Stephen Le at Cobb said the ABS (airbag sensor) codes can be cleared by the AP, but they will re-appear the next time the car is started if the seats aren't properly re-installed.
Can anyone confirm (or dis-confirm) this? Has anyone done this? I plan to use Racetech's for occasional HPDE's. I don't care if the warning lights show up during my track weekends, but I'd like to be able to clear them once I re-install my factory seats.

Dude, im sure if there ever was a situation where a dealer identified a flashed ECU in a car still under warranty they would likely go apeshit as with any situation like this and pretty much refuse any and all warranty work having to do with the car. That is why it is so important that this flash be considered a GHOST after it is set back to stock and uninstalled.
