    Problem with ECU FZR 09

    Hello guys i did a reflash R3 to a FZR 2009 and the check engine light comes on as soon as i turn it on and with a stock ECU it doesnt turn on engine check light any suggestions about this it was reflash by R&D ? anybody has had the same problem in the pass? The RPMS are fine and it turns on fine but check engine light is on hadn't test on the water since the light there is annoying.

    I have used several ( 7-8 ) of R&D reflashes and never had a problem with any of them. You need to look and see what code is being give from the check engine light coming on first.

    I don't have any machine to get the code and when i switch from R3 ecu reflash to the stock ECU engine light is gone. and before with same ecu i had no engine light.

    Is this ECU from your ski or from another ski? If this ECU is from a SHO then yes it will have the check engine/ beep sound because the SHO has cruise and the FZR doesn't.

    yes i had R2 in this ECU and was running fine with no problems and no check engine light. The problem is when i got it back frm R&D and as soon as i started check engine light then i switch to stock ecu and no engine light did switch again to r3 ecu engine light switch again to stock ecu and no engine light. so it's no the engine its the ECU that it making trigger the engine light.

    How do you know its the same ECU, could have mistakenly been switched?

    Because when I sent it I took a picture of the ecu and its the same number I may have to sent it back to r&d for them to check it
