Estimating airflow in lb/min formula
Does anyone have a formula that will estimate airflow from rpm, map, iat, and baro? Trying to plot where my engine is in the turbo compressor efficiency map for it.

That will work going forward, but I'll have to play with that formula to see if i can get megalogviewer to display this with existing datalogs

There is a calculated field called Mass Air Flow.
That calculated MAF from fuel flow and your AFR. It takes injector size in lb/hr and displays MAF in grams/sec

Thought I'd give closure to this thread and show you my end results.
