bringing this backup anyone know what 0-15 on that chart references too?
I would understand what 0-5 would mean in there but not 0-15, guessing some metric measuring of airflow.

Came across this looking for the same information. Might be psi. Atmospheric pressure at sealevel is 14.7psi so you're unlikely to have readings higher than 15.

My guess would be manifold vacuum in PSIG. So, 0 would be WOT.

That'd be a neat trick considering the OEM ECU has no pressure sensor to detect manifold pressure/vacuum.

The numbers are likely arbritary and rather meaningless unless you have the OEM curve for the MAF/AFM.

And 15 will be WOT not 0...
