Working on a 2011 Colorado 3.7 to 5.3 swap, i cannot perform a segment swap between a 3.7 and 5.3 file because of OS differences. From my research so far, it appears that you can use the same E67 ECU. Do i need to flash this with an MDI 2 ( I have access to one) and use a different VIN for a V8 OS? Or can i license a 2011 Colorado 5.3 file from the repository and do a write entire? Thanks in advance.
