I have a 2010 Camaro L99/6L80E. Previous Tuner lost the ecu when building the custom wire harness so it will run in my 1970 Camaro. I do not have a VIN from the donor and assume I need the ACDelco 12633238. What does it mean when they sell it with 2nd MPU and without calibrator? Is this something I can do myself with the right hardware and software or best left to a professional tuner? Thanks in advance for the help.
