MAF Scaling - Calibration

and here's how you build that graph

Label: you can call it what ever you want "MAF Tuning" or "LTFT+STFT MAF" whatever

Parameter: this is key and you want to select the LTFT + STFT [Math] function

View: make sure it's set to Average

Decimals: set it to 2

Function: we will talk about this later, this is a bit advanced

Cell Hits Required: make it 20 or 50 as long as it is more than 1

Shading
High Value: 20 or 25 red usually to show lean
Low Value: -20 or -25 green usually to show rich

Column Axis
Parameter: select the Mass Airflow Frequency [Sensor]

Values: cut and paste these from the MAF Calibration section Airflow vs Frequency table in the VCM Editor by right clicking anywhere in that table and choosing Column Axis / Copy Labels
