WRX maf sensor

[00imprezars]

ok ive been doing alot of research on here all day and found mention but no actual fact that this could work.

my setup will be sohc rs heads with a wrx intake manifold run a vf22.

now i would run it with stock pipes into a stock 02-up wrx intake box. can i use the wrx maf sensor?(along with a safc or something)

this is going to be on a 91 leg turbo

thanks

What year wrx?

A USDM Wrx does not have a MAF sensor, it has a MAP sensor.

oh so any usdm wrx/sti uses a map sensor right after the air filter right?
thanks

i dunno, i was under the impression it uses both, can anyone clarify?

Sorry, you are right, the wrx does have both. However I dont think it would work, but it may, just because the calibration/tolerance would be different. I think they even have a differnt number of wires. But who knows, it may work with some re-wiring, and a wrx ecu.

what we need is someone that is smart with electrical to make a maf translator like dsm's do being able to use the gm maf.....someone must know how to out there

You need to have the transfer function equation for both MAF sensors before you can really do anything....that's really the issue.
