Vehicle- 2002 Chevy duramax

I'm trying to put my diablo tune from my 2002 duramax on my 2001 duramax. I set the 2002 back to original tune settings, and when I try to put the tune in my 2001 it says that it is locked to another vehicle.


Please help!!!

sounds like a very old tool that does not unlock when you restore.

can be sent in for $99 hardware upgrade to make it work.

Thanks
