91 Octane

First logs single turbo 335xi

Here are some observations I noticed while logging and regular driving. I have a rough idle I raised my idle to 800 rpm and I still notice it a bit. During the log with the Mac solenoid connected to the car it will hit 7k rpms but won’t shift on its own. Once the Mac solenoid was disconnected during that log the car did shift at 7k rpms on its own. At the end of each log the car had a combustion misfire, Another thing I’ve noticed is that after we placed a new set of 2 step cold spark plugs after a day of use they had a lot of carbon build up.
