    Have you verified no vacuum leaks? If so, have you logged your desired air flow by ect?

    so you are saying you swapped over to a cable driven throttle body vs the factory drive by wire? Some p59 ecus are able to do that but I think most aren't. The ecu needs to have a chip inside the ecu to control the Idle Air Control motor.

    gocha, I can see in your log that your target idle is 800 rpm but it is idleing at 1000 rpm with your adaptive idle spark retarding timing like 10 degrees and your IAC is all the way closed. What you should do is get your car up to temp and let it idle in park or neutral and close your throttle blade until you get your desired idle and your IAC is starting to work. Then you have to tune the BRAF tables and then go from there

    close throttle blade and get warm idle on target rpm with IAC at about 80-100 steps with 10-13 degrees.

    its got too much air and until it goes into adaptive idle it cant control idle rpm

    make sure fueling is spot on
