Hi all,

A question regarding rescaling/calibrating the MAF-sensor.

If I don't have the commanded AFR as a log, why not just use the fuel trims as a guidence? I mean, if the total trims are +10%, why not just use those data for calibrating the MAF-sensor.

/Simon

You can definitely use the fuel trims data when calibrating the MAF Sensor, but some ECUs only use trims when they are in close loop.
