I just did abit of reading, and came across this :-

"Well Guys and Girls, I tried everything this weekend to get the P12 MAF working with no luck.
It looks like consult 2 Maf’s seem to return a different voltage to the ECU the ODB 1 units.
The voltage being returned is to low causing the ECU to have a error code."

This would be a 20V afm on a 20VE, so i guess that is a no go?

Seems almost if not everyone is using the Q45 AFM

You do have a Nistune so get your hands dirty and manually modify the VQ table in the low resolution voltages for the Q45 MAF until it suits, otherwise the Lightning MAF is a better option to try

Use the Q45 over the 20V. The Q45 is cheaper, easier to get hold of and easier to tune.

Ive used q45 mafs on 2 differnt NA cars with no problems at all, no issues with resolution or load scaling. One was a 20v engine, other was a sr20de autech engine.
