PCM instalation problems!
 

Hey there, i received my tuned PCM from Reptile off the grand prix forums, I tried installing it today but it has been a no go, tried undoing battery and pcm, 15 min on on, then 5 sec off x3 even tried the 35 min on and nothing, has anyone had this problem??

After 7 long hours finally i got it working......

what was wrong with it?

Wouldnt start, didnt even knock or anything, for 7 hrs straight

did you do the relearn process the whole time?

I had to do the security relearn thing and I waited longer than the instructions stated and that did the trick for me.

Glad it worked out! Do you feel the power?

I feel it...but ended up with 8 codes, airbag light on and somewhat harder tranny shifting

I got the airbag code. I got my PCM through ZZP so they suggested that I send my original PCM back to be reprogrammed. I kept there's until I got mine back. Plugged it back in and I haven't thrown any codes or had any problems.

Shifts are supposed to be firmer. Thats the main reason people get these tuned.
