I currently have a 85mm ZO6 MAF on my LT1 car that I got from Ed Wright a few years back. He programmed my PCM to work with it and it has done great! But now I am turning the LT1 back to stock and modding my LS1 car.

Will the ZO6 MAF work on my 99 LS1 car without any issues, or does the PCM need calibration?

Thanks,
Jeff

it'll run, but there is a MAF conversion table in the PCM... that SHOULD be changed to match the new MAF.

im buying HP Tuners next month for 2002 and 99s... so if you want to, i could change them for you later...

There is a table for it. Not sure where it is.

Theres a Travis lurking on every board I'm looking into the HP Tuners as well, but have "NO CLUE" on where to start or what to do? Maybe you can teach me something about it.

Thanks,

Yes you have to modify the program.

Jeff, the LT1 car needs the MAF tables put back stock, and the '99 car should be close if you copy the MAF tables from a '99, 200 or so model 5.3L pickup truck. The same wiring pigtail you got with it will work on the '99 car.

Good luck, Ed
