View Full Version : ka-MAF voltage vs. airflow (S-AFC, or other airflow data wanted)

Does anyone know the voltage/airflow relationship from the stock MAF.
is 0.75V around 25% less airflow than 1.0v, and 4.75v 5% less than 5.0v?

I'm sure it's not a completely linear relationship, but if anyone has airlow readings from the S-AFC(or any other means) per MAF voltage( i.e. deduced from injector flow/ duty cycle).

At least if anyone can post idle and max airflow rates or S-AFC data (specify ka, ka-t).

its not a linear relationship; more info at FA

yup, i was reading Z32 maf installs using the AFC on a KA motor... saw lots of voltage numbers being tossed around for the SR20 and KA24
