Hi

I am running a full sd tune, otr, LT headers and a 216/226 cam.

I know the process of measuring the idle airflow with a maf but was wondering what the process is to work out the min idle airflow table for a l98 gen 4. That's in a custom Os maffless or SD mode.

I have found a VE airflow pid in the scanner but the figures seem high and dont know from what sensors / tables that pid is getting its calculation.
