so, I bought a PCM from a local junkyard that is for my 01 mc ls, and i got one from an alero. the service part number is the same, so I found out that I need to "reset" it. how would I go about doing it? I wanna send in my stock MC one to be flashed...

 

i think you have to take it to a chevy delership and have them reflash it im sure they will need your vin so that it works for your car
