Rich idle on 2 bar, SD Only tune.
Having a rich idle issue that I can't pin down. It wants to idle at around .7 lambda no matter how much fuel I take from the main VE table. It is also very rich on those areas at very low load and part throttle.
This is a turbo 400, turbo 5.3L. That otherwise runs and drives just fine. Perfect at anything over light load but will not lean out at idle or very low load. Fuel pressure is also spot on. I have a few issues to work on but it's close everywhere else.
