Yesterday BMWnation came by to clear adaptation with INPA. He is running Giac tune. The weirdest thing after he started the car was it was running erratic. Rpms kept jumping up and done so we looked at the codes. The error was throttle adaptation values. To fix it we had to disconnect the battery and then it ran fine again. Very weird after resetting the throttle adaptation it ran like that till we unhooked his battery. Anyone know why?
