I work with the same engeneer Mauro the "ebay guy" did and now I'm in charge for US.
I don't know if you already know that after YEC reflash, you can chose to have the oem display mode or the YEC one, whithout speed and with temeperature oversized.
The other big advantage for EU models is to maintain the oem wiring harness, so lights, horn and fans still work.
For R1 11-12 the conversion includes the activation of YEC traction control. If installed on a 09-10, it needs the YEC dash and the front-wheel sensor to work.
Apart from R1 and R6, also others ecus can be modified... suzuki, honda, BMW and Kawasaki altought in theses cases, it is necesary to open fisically the ecu to change some component and reprogramm the processors. Yamaha instead doesn't need ECU to be opened and everything is made by software.
