Graph looks great, Smooth those fuel maps and revise those timing maps. See how your pulling timing towards redline? Your going from ~27 degrees to 25 degrees, thats backwards and will cause your car to 'nose over' so to speak. You should be adding timing as the rpms progress.

VE decreases after peak torque so fuel requirements go down to acheive same AFRs As RPMs increase, there is less time for flame propagation so timing needs to advanceNatural Aspirations wrote:Thanks! For some reason I thought you were supposed to pull timing after peak Tq. I wish I remember where I read that....
