MAF Scaling without Raw Volt/Hz

Hey guys,

The MAF Volts or MAF Hz raw output from the sensor is not always a PID available via OBD2.

My question is, if the only PID available is the g/s actual MAF value, is it still possible to scale the calibration accurately?

Or are there caveats involved in doing this?

If you have sensor output, or calculated airflow, you can do the job.

Rather than referencing MAF volt or frequency in the MAF scaling table axis, then adjusting the associated airflow value, you go right to the airflow value in the table matching the area of the logged data that you want to adjust.
