G'day all, drove the Z today and out of no where started to ping past 3000rpm. Have a Conzult LCD in the car and noticed the idle timing is fluctuating between 15 degrees up to 25 degrees. AFM readings seem normal and TPS hasn't moved past 0.44V at idle. Haven't ruled out a boost leak between the AFM and turbo which may be causing it but the timing is a bit troubling. I recall WazTTed and JEDI a while ago saying a faulty neutral switch which can cause big jumps in base timing (in AT to MT converted cars) however my ECU was always a manual ECU which should not affect timing in such a way? Anyway, I may just ground the neutral switch, Waz reckon you can give me a breakdown of what needs to be done? Could I just ground PIN 44 coming out of the ECU?
