So, apparently my Ecu is stuck on error code 55, which according to Motomatrix uk means a replacement unit. Surprisingly there does nt appear to be any 2nd hand units avaliable in their database, which is worldwide.
Can anybody help? Ideas or offers welcome.


Thanks all..

According to the service manual error code 55 indicates a key registration malfunction. So just register another key not the same key. You don't have to replace your ecu.

If only it was that simple, I ve lost the red key some time ago, and under instruction from Motomatrix carried out the ECU basic reset, which means disconnect everything for 24hrs, then reconnect. Same error code.
Water had got into the main ignition plug and the Transponder aerial plug, i think it shorted out causing the ECU to get stuck on 55.
I think i m right, but some what out of my depth.

Which part number ECU are you after, as I still have some lying around.
