MAF Tuning Idle Airflow

Post by VX L67 Getrag »

Not sure if anyone knows this but with the MAF type tuning there is a learnt airflow for with or without A/con but I can’t seem to find the relevant logged item to match up if that value is close to correct?

They also used this similar value for each boundary in the selected gear or Park/neutral tables but have never been able to find what item matches with it & the data tracing doesn’t work for it?

off the top of my head it looks like default tables for when MAF isn't connected or failed.

According to documents it uses each air flow parameter & adds them together to get the base idle airflow, but not sure how many of them there are & guess it all may make the mg/cyl figure?

EDIT: well re-read & looks like the top 1's are if fault 32 maf fail but the gear p/n are for commanded air flow & added?
