    No engines & sensors are identical. ECU differs in Cruise Assist, No Wake, etc.

    I just thought it could be a sensor that was related to the cruise or no wake but if there the all the same I can tick that off things to check

    Do you have access to the FZ ECU? You might try swapping that out to see if it will fire up. More than likely is unrelated to the ECU. Was the Motec set up for the engine you're using it with?

    phil did you replace the part under the front hatch ( the security key bit) with the motec part
    if you didn't you can put the stock computer back in and unlock it with the remote
    you can then put the motec back in and start it

    just so you know it will lock with the stock ecu disconected
    but it will not unlock unless the stock ecu is conected
