MAF Voltage is 4 Volts and WOT 6000 RPM - It is the numbers on the far right of the log I pasted in previously
I checked the throttle body. It is completely closed when pedal is depressed.
Fully depressed pedal rotates the throttle body all the way round to the metal stop at the back of the wheel.
I will also visually inspect the throttle butterfly internally, I don't think I have ever done this.
99% the alternator is weak. Has been for years.
Anyway
I will check voltage at the TPS
I will double check voltage at the alternator
I will try and rotate the TPS to get the signal where it should be.
& go from there.
Is it in fail safe mode? Or is it because of the the TPS signal is weak?
Does 16 deg timing with 80% throttle @ 5.5K RPM match the base map for a DE ECU?
ECU Talk shows no faults. Can it be in fail safe with no fault codes?
I have disconnected the narrowband sensor a long time ago and replaced it with a wideband with the signal going into an Innovate gauge and the AEM FIC.
Is a disconnected narrowband going to effect WOT?
Generally my AFRs are exactly where I want them.
