I've checked wiring from AFM. It's a 4 wire type which is a PWM type.
Scope sensor and getting good trace and frequency is shorting when rev'd but the live data is staying the same. when I take air intake pipe off leaving air flow meter monitoring no air intake the live data still reads 495mg.
So i'm thinking the ecu is not reponding to afm.
