I’m a member of xborg a german community about buell motorcycles (rr, xb and co).
A member of it crafted this bluetooth modem named XBlue. In conjunction with EcmDroid it is possible to read and write the engine control unit (ECM).

EcmDroid is an Android application based on EcmSPY.

This one just as a minor update, I  keep you posted!
