Just install it. It may run a little rough for a few seconds, but then will be fine. There is no reprogramming required to test it. If your state does any type of inspection where they plug into the diagnostic connector, the replacement ECM will report the incorrect VIN, but that can be corrected using the TechStream tool (if the ECM solves your issues).
