maf help I have a 85mm maf part# 25168491 for my ls swap into my 69 camaro. Trying to tune the car with my hptuners and i'm getting funky readings on the MAF. I purchased the LS1 PSI harness with the 5 pin update for the 5 pin MAF. Does anyone know the connector sequence on the 25168491 MAF? I saw conflicting threads showing what A thru E was on the MAF? Then again hopefully the harness is wired back to the ecm correct??

Does this help? http://www.justanswer.com/chevy/4h39...ailblazer.html
According to Phillip at Bluecat tuning all of the 5 wire MAF use the same circuit numbers and pin to the PCM the same. I was just dealing with a MAF issue.

Thanks oldgoat69...it is one of the diagrams i have seen. psi wants me to rewire the connector as follows: A to maf output , B to ground, C to maf power, D to IAT reference and E to IAT output? Maybe thats the way they wired the harness??

You could run just speed density, but MAF is preferred my most of the tuners I know. Maybe check out the HPtuners forums to get a consensus before deleting the MAF.
I dug a bit more and found this, I have my MAF pinned the same as this example. http://www.thirdgen.org/techboard/di...n-421-cid.html
