Also did you tried to measure performance 0-100 time with AP because I was trying few times and no luck I get "-" signs instead of time. Just when I go slowly to 100 kmh I get the real time WTF? |

There's an option on the AP to reset to reset to default logging parameters.

Just grab a couple logs of a 3rd gear pull. Start the log right before going WOT and stop it as soon as you safely can after letting off the throttle.

I just start the log when I get into the car then filter the data in Excel based on when the pedal is above 99%. It works for me. Although, sometimes I look at the cobb unit, and it has lost communication with the ECU, so I have to do my pulls again.

Yeah, that definitely works. It just adds a couple steps for people that want to open it in VD.

I'm new to VD. How accurate is it? Do throttle closures make it read higher? Because I'm still trying to tune out my throttle closures, and VD is reading ridiculous amounts of rwtq.

If you're FBO and tuned for an e40 mix +450rwtq is probably about right.

A P29CF is a misfire in cylinder 3. Check the misfire sticky at the top of the first page

Do a 3rd gear pull (gas pedal all the way down)starting at about 2500rpms and go to about 6500rpms. With an auto it's a little tricky to go wide open throttle without forcing a downshift, so it may take a little practice to get used to not hitting the kickdown switch.
As far as starting the log, that's not a glitch. That's the way it's supposed to work.

Yeah, that's semi-normal beahavior. When making a lot more power the weakened plug/coil/injector is pushed past it's limit.

I have the Cobb Stg 1 Aggressive on 93 octane pump gas. The car pulls strong, but seems to get out of breath at higher rpm's. I installed new BMS DCS intake, but it didn't make a difference. I collected some data logs from the Cobb, but I really don't know what I'm looking at. Can someone please tell me if they look normal or if something is wrong?
