Hi,
I'm about to replace my broken E38 ECM in my 2008 Corvette C6 with LS3. The new ECM is from a 2008 Corvette Z06 with LS7.
Both has the same service no #12612384. The broken ECM has os no 12617631 and the new has 12613139 (on the label on the back).
Are these two os versions compatible, so I can safely make a "write entire" with my HP Tuners of my old tune file to the new ECM?
