If this is for a Q45 4.5 liter?: All assume 174F coolant temp!Idle 1.12- 1.18 volts> Cruise 2,000 rpm 1.8- 2.2 volts, WOT 4000 rpm ~~ 3.7-3.8 volts, WOT in gear at 6,000+ rpm ~~4.2-4.3 volts

Obviously the MAF must MATCH the ecu transfer function equation.

Or are you trying to jury rig a Q45 MAF on a smaller displacement engine?

hey thats for the breakdown. im actually using it on a rb25det r33 skyline engine. the power fc give me options on maf voltages and i was unsure which one to use.
