Can you use and LS1 MAF on an LT1 motor?
besides looking the same, are the calibrated differently, will it screw the PCM up plugging one in and running the car with it? curious because I can get my hands on an LS1 MAF to test out on my car, my GMAF crapped out on me.

Any insite is greatly appreciated,

 

It should work OK. I remember swapping a granatelli from an ls1 in my car for some testing and it worked fine.
The calibration is slightly different, however.

 

If I reset the PCM before installing the LS1 MAF, is there a possibility the PCM will relearn the calibration that the LS1 MAF has? Thats the way I see it, correct me if I am wrong

 

No, the MAF calibration is located in the main calibration, so it won't get updated with a PCM reset.
