AFM Flap all the way open.. AFC says 80%!?!
 

Does anyone know how to properly calibrate the afc so that it reads 100% when the door in the maf is fully open?

A few other people had the same issue...
They reset their afc's and the problem worked itself out..
make sure to set the vehicle type correctly.
~goodluck :)

yeah, i tried that but im still only coming up with 80%

Maybe it's still not holding the settings?

Only other thing I can think of is that maybe the afm isn't sending the full range of signal to the ecu? unlikely, but in the factory shop manual, there is a diagram for all the pinouts on the ecu and their voltage ranges. (page 81-83, don't remember which section exactly.)

Its a brand new maf

Adjust the TPS

I was actually planning on wiring it up to the pressure sensor... will that fix it too?
