I searched but haven't found a clear answer.
On a LS3 swap utilizing a 2011 Corvette OS E38 that I need to replace the ECM on, can I just buy a new (blank) E38 (correct service model i know) and then use my current tune and add the slave data do a write entire and I am good to go?
When this feature came out to add the slave data, the notes seemed to imply this, but i have never tried it as have not needed to do it before now
