MAF Scaling - Calibration

After we made that one simple change in the VCM Editor to disable Speed Density for the duration of our MAF calibration, now we need to add some Channels in the VCM Scanner.

First I would like to show you the bare minimum of channels that it takes, we basically need two things:

1. the Mass Airflow Sensor frequency

2. the Short and Long Term Fuel trims (all four of these channels)

that's it with these five channels we can tune the MAF, however later I will tell you why you may want to add some more channels just so you have some perspective as in how fast were you going at the time, what was the engine RPM, what was your intake manifold pressure like, what position your throttle was at, were you in Open or Closed loop, etc. just some nice to haves.
