Installed 08 ECU into 09 now FI light
I installed the ecm from an 08 bike in order to get back my power which is lost on the 09. However after the bike starts, I get code 25 which the SM states is a knock sensor problem. I know I didn't go anywhere near the sensor so I don't know if this was just a stored code in the 08 ecu that was never cleared or what...I'm about to go back and try to clear the code with a jumper wire the DTC connector and see if the code flashes again. If that doesn't solve the problem, then I'm thinking it may be a bad ECM as I just started the bike with the 09 ECM right before taking her apart just to make sure everthing worked ok and no light. I will know if it's a problem with the 08 ECM if I connect the 09 ECM back and the FI light goes away. This is a non CA bike.
Ok, I just came back from clearing the MIL code. Switched back the 09 ECU and no code. Put in 08 ECU and code 25 again.
Any other ideas?
I hate 09 fairings
