Volumetric Efficiency VE Table Calibration

Now in VCM Editor we need to trick the PCM into thinking the MAF has failed in order to do that we go to Engine Diag \ Airflow tab \ Mass Airflow Sensor section and set the MAF Frequency Fail High to some low value such as 100 Hz

Note: back in the day and especially on Camaros or Corvettes people used to just unplug the MAF sensor however we can't do that on the truck engines since that will also unplug the Intake Air Temp sensor as it lives in the same housing as the MAF sensor.
