I wanted to report back its works! I used a 2001 corvette xdf file to rewrite it and put my tune back on it thanks

Sweet I've been racking my brain for acouple of days

1271005 is a custom OsID ... You have the bin off it ?? If you do, you can get the Key from the bin at 4002/4003 (or 6002/6003), and use PCMHammers ability to use a user defined Key to unlock it from now on. The seed is at 4000(or 6000) and 4001(or 6001). If not, it's easy to brute force with Unive...

I did get the bin off it ill try thoses options thanks i appreciate it

Oh okay that's a good thought it has a tune and a tuner lock on the pcm I opened the case and forced it to unlock it briefly to retrieve the file I did that successfully here is picture of it []

Hey fellas iam new to using pcm hammer and tuning in general. I have tried to search for the correct Os identification number for my pcm. But I can't find it mine is Os ID 127005 out of a 2000 VT ss commodore. Do I use the Universal patcher to find a suitable one?
