    E40 Idle ceiling

    I am wondering if there is a maximum limit to the idle in an E40.
    No matter what I set the base idle to it will never idle over 1200 unless I am commanding it manually with the scanner

    Would anyone be able to shed some light on this?

    There likely is.. Is it not defined in your tune?

    Post a file and we can help you find it.. 1200 is the typical GM high limit going back to GEN 3 cars.

    If it is defined in the tune I cant find it. I can go to idle and base setpoint and take it up to anything I want but the car wont react to the new setting. Just goes to 1200
