    Throttle % fluctuating at WOT

    I've attached the scan log(Recorded using 2.25). What is causing my throttle position to jump from 88%(WOT) to 60%(while still at WOT)? Ive searched and cant find anything.

    what kind of vehicle is this? Looks like you're hitting overboost protection.

    Also this thing is running VERY lean, dumping fuel almost everywhere at +15-20% at all rpms and under WOT. Would be good if you posted up a tune file.

    Fixed it! One of my tables had the incorrect rpm values.

    Imma bump this. As far as adaptives go will hptuners give us the option through scanner to clear adaptives? This is probably something I should email and ask but I figured I'd shoot it out. I believe adaptives to be one of my big issues lately with over boost n such.

    you can run in open loop all the time if you are looking for zero adaptives.
