got a intermittant hesitation at part throttle and was thinking the MAf may be the culprit. wanted to swap a known good MAF onto the car to verify/disprove this, but the MAF is from a 88' 350 GTA. are the V6 and V8 MAFs the same or will this not work?

 

not the same. do you have a check engine light?

 

actually i think they are... i "think", so don't take my word for it completely..

not the same part number.

 

I've heard of people doing it but I think it will richen the engine up due to the v8 pulling more air across the sensor than a v6 would .

 

i have gotten a check engine light, but havent scanned the code yet. the light only came on when i was backing up into a parking spot, so its more than likely low IAC counts or something

ill have to check it with my scan tool and see

 

you dont need a scan tool.

 

i suppose i could use the old "paper clip trick" to check trouble codes, but i think hooking up my scan tool would be quicker and easier

 

They're not anywhere close. The v6 maf is a frequency film (digital) maf and the v8 maf is a hotwire (analog) maf that requires a whole wiring change to add in the extra realys to run it.

 

Not to mention swapping to an ECU that will support MAF readings in changes in voltage rather than changes in signal frequency. The burn-off relay is the least of the problems.

If someone were feeling particularly stubborn, though, one could probably program a small pic microcontroller to perform the translation. I'd love to see that one done.
