I purchased a crashed Sporty with a missing ECM, and so of course I need to get a ECM. A new ECM costs $350 so I'd like to get a used one if possible. Can I purchase a used ECM (with the correct part number for my bike year) and have a Dealer reprogram it or do I have to buy a new ECM?

 

A used ECM that is the correct part number for the bike will work fine. If the bike has a TSSM, you'll have to marry the ECM to it. The procedure is in the service manual or you can do a search and find it.
