MAF Scaling - Calibration
With a mental picture of our current MAF graph we are ready to put our PCM in MAF Calibration mode. In order to do that we must disable Speed Density, in other words we don't want the MAP sensor and the VE table assisting or correcting how much air is flowing into the engine, we want to solely rely on the MAF so that we can calibrate it.
To achieve this isolation we go to Engine \ Airflow \ Dynamic tab \ Dynamic Airflow section \ and set the High RPM Disable to 200 rpm
now if we glance on the help section below we can read a rather confusing description:
"[ECM] 3003 - Dynamic Airflow High RPM Disable: Above this RPM use filtered MAF airmass for airmass prediction calculations."
yet watch what happens when I only add one word:
"[ECM] 3003 - Dynamic Airflow High RPM Disable:
Above this RPM use only filtered MAF airmass for airmass prediction calculations."
