Here is my delema. I have a RR pcm with my tune on it for my 2001 Z06 and i want to take the RR out and put the stock pcm back in but my stock pcm has a stock OS in it. I dont know what i am doing wrong but i cant find a way to get the OS on my RR onto my Stock PCM so i can get the RR cal onto the stock PCM. My RR pcm is running the 02020005 OS and my Stock is running 12593358 OS. What am i doing wrong that wont let me do a Case Flash to put the 02020005 OS on the stock pcm. Also both PCM's are the same VIN...and so on. I need to get my car running by tomorrow can anyone help!
Also i have the commercial lic for my EFI live and i am using V1
