Please post your setting. I'd like to compare. I am at IACV -2 and CO 3.8. look weird. if I raise the value of the stepper, the idle goes to high and bike hard to start. stepper make Psssit Psssit noise too. Also with raised value, I dont have the same RPM in neutral and in gear clutch pulled (+500rpm)
Rule one Klanking, if it's working don't eff with it.
