Can any E38 OS be loaded onto any generic E38 ECU, for example, out of a junk yard? If I found a 2007 Yukon ECU and wanted to have a 2007 Manual Corvette OS on it, can that be done? This ECU is going into a old truck, and the corvette calibration would be a better fit. Any issues with this? Can I get a generic E38 ECU to look, software-wise, exactly (OS and calibration) like a specific vehicle?
