afc question.

[blacktsi95]

on the afc readout, it has an option for Kar, and it will read a 2-3 digit number followed with hz. is this the maf signal showing air flow? if so, is there a formula to convert that into cfm, or lbs?

 

[marcmsj]

Kar = Karmen

And yes it's the raw maf signal output the the maf puts out in hz, the higher the frequency, the larger the airflow is.

I don't know of any conversion method.
