spark timing table in $6e

I'm working on an ARAP based code for my car. From what I've read LV8 is just the airflow in gps. If that is the case and LV8 doesn't get combined with the TPS voltage in any way then half of the table for the spark map is useless. You can't have 200grams/sec of air flow at 1500 rpm so what ever value is in that spot on the table would be unused anyway. So basicaly what I am asking is if the LV8 is just air flow or if it is a combination of airflow and throttle position.

thanks
Mike

LV8 is neither. It is Airflow divided by RPM.

LV8 = AirFlow/RPM

Were did you read that?
