Default Re: XR8 idle hunt (video)

A couple of things look strange to me. Your tps voltage stays on 1.18v even when you blip the pedal. That’s not what you want to see. Your MAF voltage is approx 0.8v at idle. Is it a stock MAF? Usually a stock engine and MAF are between 0.95v and 1.05v at idle, or thereabouts. This suggests to me that air is getting in elsewhere. Your spark values are chasing up and down trying to stabilise the idle 16-29 deg. If it’s happy it should only fluctuate a degree or two around 18 deg.
