I recently bought a tune from the guy on grandprix forum and here I am for 2 hours trying every which way to get the pcm to work. Im thinking its in the tune but not sure, I did every way I can think of to get it to work...

 

Just won't turnover? Did you go through the security relearn?

 

it wont turn over or anything, I tried all relearns I've seen, i turn the key to crank it and it goes black then after I let off it gauges all come on. I dont know, I know the radio said cal error..im at a loss maybe the tune wont work on my car..

 

When you did this relearn did you have everything close, doors and truck etc??? Not a low voltage battery?

 

It won't even crank? Dead battery possibly?

 

It's hard to tell though because it won't crank when doing that procedure; at least my Monte didn't until the relearn was completed successfully...

 

When I changed my pcm it would crank but not start until the relearn was done. 2004 Monte Carlo ss

 

I had everything closed but the hood, but there isnt any sensor on my hood area, had the battery hooked up to a charger, it dont crank, I swapped stock pcm back in fired right up..IDK..

 

Im pissed it wont work, I had to give up for the night I had to go get my son...anyone have any ideas

 

That's interesting. Also, some have said their car fired right up so who knows...:laugh:
