Hey guys, well we are having my alternator replaced at the dealer, but they do not know I have pieced my own stage 2 wannabe kit together on my own. So what I need to know is, will they touch my pcm/ecu? If they do, then I need to get my tune back from my tuner.... I figure they won't mess with it, but you never know!

 

there has never been an alternator that I have replaced that ever had anything to do/related to the PCM. I say you will be safe.

 

Cool good to know thanks!! Nice 'balt btw. That's one of the only cobalts that can pull the "wingless" look

 

x2 they don't need to even mess w/ anything else .. I wouldn't worry..

 

thanks man.

 

eh...I wouldnt be so sure...Depending on the tech who does the job, When i was in school i was taught to ALWAYS disconnect the battery to be safe with doing anything with heavier gauge wiring via..Alt, Battery cables, Anything under hood basicly, Correct me if i am wrong.....
