    I think he means that from stock idle the car stumbles slightly when revving the engine.

    The tip-in enrichment tables are basically for tuning in extra fuel compensations under specific conditions where there are abrupt changes in throttle opening angle over a certain percentage. It is not "normal" to have to need to increase idle engine speed to prevent stumbling on a stage one tune, but what you're running is a one size fits all base map anyways, so it's not really tailored to your car. It's pretty hard to really tell what's going on without a WBO2 installed to log, but you could always try lowering your idle back to where it was and increasing your tip-in by about 40ms and see if it's better or worse, then decrease it by the same amount and try again. check over the logs carefully and see if one or the other increases low load knock events. If so that's a bad thing and you want to head in the other direction.


    For what it's worth, my warm idle speed is set at 1000rpm..

    Yes, in Accesstuner Race you should be able to adjust it. You might want to hunt around for vacuum leaks first tho.

    You shouldn't be modifying anything that you don't understand.
