    Can i swap my FZR/FZS ECUs?

    I have a FZR & a FZS both 2009, one ECU has been sent off for a R&D reflash, can i put the original ECU from one to the other (as the ski with the standard ECU cant be used at the moment and i want to go out!!).

    Hope that makes sense.

    Yes Definitely, its the same engine which uses the same ecu and same parameters. You can even swap a FZR with a SHO ecu because they all have the same engine, and this is what most people do when there getting there ecu reflashed if they have another sho engine which there not using.

    Yes you can switch from a FZR to a FZS with no problems.

    Hello waterholics you can switch from a SHO but you will get a check engine light flashing because the SHO has cruise control and the no wake and it will trip the check engine light.

    yes you can, the fzr and fzs share the same ecu.
    if you use a sho ecu on a fz you will get a beeping alarm, sho ecu have cruise control/no wake mode fz doesnt.

    Remove black cover in the electrial comparment. It's a little trickey to get the cover off with the rear seat grab handle and metal plate in the way but you'll figure it out Then it's pretty stright forward... just some wires to disconnect.
