Rev Limiter & Gear Change

    1999 840 Auto


    Fitted:
    LSD 3.91 diff from E34 M5.
    Custom exhaust with 100-cell fast-flow cats
    Stock engine (M62) and Auto-box.


    Problem:
    When in Sport Mode and under full acceleration (accelerator pedal to the floor) the final gear change to top gear is faltering as the revs hit the limiter-level which causes a miss-fire right when the gearbox is trying to change gear.


    Anyone know what I can do about this? I have looked (without success) to find someone who can remap the ECU and Transmission Control Unit together.

    Timm,
    It's going to be a little while before i can answer your question as the car is now in the bodyshop.

    Are you saying, you're trying to shift the rev-limiter up a bit?
    Not really a healthy solution... :naughty:
    Probably, to better use the 3.45 diff is not what you wanted to hear, hu? :laugh:
