Default need engine airflow data (VE, etc)

I'm trying to calibrate my AFM cheater map.

I need to know either the actual airflow at idle or various RPMs in grams/second (mass air flow) or the VE at various points.

soooo...if someone has an OBDII scanner and an 01 car that's mostly stock, can you take some datapoints for me? the OBDII port should show airflow in g/sec directly. just hold a couple RPM points and idle and let me know approximate values. I dont think I need to be dead nuts, just close.

thx.

idle between 2-4 grams a second depending on engine load. ( ac, lights, etc perhaps up to 5 grams a second with everything on )

you can figure it out by yourself though without data other then displacement and get a good idea of what it maybe around.
you really can't say this rpm = this much airflow

that guide under fueling paragraph 2 should help you out.
