When people here talk about Base Airflow, do they mean the Airflow Final Minimum table? Base Airflow sounds like starter values the PCM works with to determine desired idle airflow, while Airflow Final Minimum just sounds like minimum values. Unfortunately I can't find the former table anywhere. Increasing minimum idle airflow could of course have the desired effect, but wouldn't adjust for things like weather or the air conditioning compressor kicking on.
Thanks. I've got a heads/cam LS7 with a NW 102 and the crankcase vented to a catch can. The TB scalar is set properly but it doesn't want to idle with much MAP (i.e. it just stalls). Presumably this is because of the lack of a PCV system, and me not knowing how to increase base airflow (yes the ECT scalar is set to 7,190).
