Hi Digito. sorry for not getting back, have not used email since being on leave from work.Thank you a lot! I ve just installed an usa ecm on my euro XX and worked perfect !
That is great news about ECU. I remember my relief when the 99 USA ECU worked on mine. The mapping of the earlier and later ECUs, however, was not the same. I don't quite get as good fuel economy with my 99 ecu, and the power delivery is slightly different with not as much surge as later ecu. I would describe the 99 ecu as having more linear power delivery.
If you get around to it, put up a picture of your bike.
(at the moment by naked bird is mothballed as I am having charging problems that I don't have time to sort out. I think it is regulator.)
