It's much more than 'translating' the fuel map to the different firmware. They actually store the map in a different memory location as well, thats exactly how ECM's get 'bricked', by bypassing the securities and burning a map from a different firmware version.
PM AZMidget on here. He may have access to a later map like that. Try Buelltooth.com and ask them too. Maybe Buellmods.com? If you have the capability to burn a map, then you have the capability to read and store one from another bike (that is stock) as well. Any local Buellers to you?
