Alright guys I'm a little bit at a loss right now hoping someone can help me asap! Alright I just l67 swapped my 01 se Bonneville, I'm at the point where I need to flash my pcm, do I need the file I'm going to replace the current pcm file with to be the same exact OS or can it be a different OS? I know 97 and 98 files are different, will I be able to use any 99-03 file? Cause I'm having trouble finding my os online. Thanks guys for the help

I don't know for sure, but hard to see why you couldn't just put the '00-'03 SSEi OS/tune on it and call it a day.

Beware of potential gearing differences if the trans didn't come from the donor car. Otherwise, any 00-03 SSEi tune should work, but will still require a security relearn.

Trans is from the same car I did the l67/4t65ehd swap.could any of you point me in the right direction to find the os and file I can't for the life of me find the files, and I've been asking around on forums but no has answered me back yet. Thanks guys

Or will buying a 2000 gtp pcm with the same OS # as mine work?
