I am having an issue with afr,s jumping to lean under wot at gear change.Afr's are at a steady 11.1-11.7 until the change from 1st to 2nd and then they lean right out to 16+.
Any ideas?
Thx Brad

I've seen it too, heard it called clutch-fuel-cutoff... I don't know what the answer is, but I have seen it more than one time in the 2-bar tunes and always with an M6
C5s have Engine-Fuel Control-Fuel Cutoff-DFCO Enable Clutch Transition. If you have it, disable it. C5s are factory disabled by setting the Temp to 141*C.
