Now I've fully refined and polished Monty's stage 3 ECU calibration the results on this one are in, the optimal idle speed where Stage 3 Monty holds a nice smooth and consistent drum roll idle is 1,175rpm.
No lope, no hunting, and no choppiness whatsoever!
Whatever happened to that that lightweight flywheel? Maybe there’s scope to trade off a little idle quality for even more engine response
