I don't accept trims very often, although when I do I don't see much of a change and only in the lower RPM's. My Schnitz map may already be dead on. Maybe I'll start checking the trims every pass to see if it makes a difference. So far I've lost interest in the auto tune and don't think it helps much for racing because it takes a lot longer to calibrate itself than a 9 or 10 sec pass and I can't find a place to stay in the upper rpms for to long. My reason for buying it was to stay off of the dyno but it looks inevitable for a proper tune.

I would not take the changes for the lower throttle positions....
I think that the autotune doesn't handle the throttle snapping open and closed very well. When the throttle closes , the fuel goes lean because the ecu sends no fuel and the air valve opens ( if you still have that enabled) . My data logger shows the afr going to 17 when I get off the throttle. I think the autotune sees that and wants to bring the afr back to the target ... so I dont trust the 2% trim at all.
After I rode around town without accellerating hard, I accepted the trim values. Then I zeroed out the 2-10% columns on the target afr so it would not change those numbers anymore.
