good morning retrax: i suspect that your receipt from 2007 that came with bike is showing the dealer flashed a race map into the stock ECM. the part # you listed on your response is for the stock ECM in bike under seat. an EBR race ECM have their own markings and part #. in answering some of your questions....yes....EBR ECM and stocker physically the same, same location on bike. the EBR race ECM is expensive. i suggest working with what you have, either borrow or buy the ECM spy program CD and patch cable, set it up in your garage/shop, have someone familiar with it help you or i can email you directions, get the program up and running and plug into your bike, see what you have. if you have the race maps flashed onto your ECM you probably just need a few adjustments, checks and tweaks to make it perfect. on exhaust both drummer and Hawk very good. i have Hawks on all 3 of my buells and they're great...and reasonably priced.
