I don't know how to MAF Tune.
I know $6E (1989 TPI) has MAF Tables . . . Volts vs Grams per Second.
Possibly adjusting the MAF Tables is how to tune a MAF system?
Back in the day, I worked on equipment that measured wind speed and wind direction with a MAF kind of system (heated wire). The service manual had procedures how to verify wind speed by measuring DC volts with a multimeter. Wind direction was verified with a compass.
Seemingly if the Volumetric Efficiently of an engine is changed by an aftermarket camshaft, or aftermarket intake system, or aftermarket heads, or an aftermarket exhaust system the grams per seconds table would need to be recalibrated too?
Maybe scientific measurements of the air flow vs voltage is needed to tune a MAF system? Maybe the factory used a scientific measurement process to setup the MAF tables? I'm wondering what the MAF heated wire voltage is when 650 CFM (old school carburetor flow rating system) of air is flowing across a 3.25 inside diameter cold air intake. Oh now we have to convert CFM to grams a second.
I'm also curious about how $6E uses the Seventeen different LV8 parameters?

MAP tuning is Kpa vs RPM. MAP sensors have a specific voltage for a predetermined Kpa. Unfortunately MAP tables are not adjustable in $8D, so a simplified tuning system was developed (Excel Spreadsheets).
