Hello, I'm new to the forum and relatively new to EFI Live, having only used tuning companies' tunes vs designing our own for a little over 2 years. I have an 2008 Chevy 2500 that has lost one of the 5V reference outputs as well as the ground for the Wait To Start Lamp and have water intrusion into the ECM case so we plan to replace the ECM. Can I install a used ECM from another truck and flash the VIN to match? Licenses go by the serial number of the ECM not the actual VIN, correct? So I will need a new VIN license, yes?

Thank you in advance!

Adrian
