Hey guys, Can anyone tell me what range (whether it be signal, earth or 12volt power) outside the scope would throw a z32afm off and put the car into limp mode. Currently have the car not revving past 2500rpm. I have checked the z32afm with a mulitmeter and had the following: Signal (idling) 1.53 - Car ignition on - .48 AFM Ground - .37ohms Signal Ground - .37ohms 12v Power - 13.89 I am assuming that the AFM is not the issue as I have two Z32afm's and there is no change between them. I have also reseted the ECU and drain the battery. The car is a R33 Series 1 GTST, with Nistune Board. No issues with tune as the car was perfect before this started to happen. Did a diagnostic check via shorting out the two wires and code is 12 which is AFM. Doing my f%^kin head in.
