    ECU Compatibility

    Hey all,

    I have a 2004 FX Cruiser HO I'm fixing for a friend. It needs an ECU.

    Anyone know if the ECU from an FX-140 will work for this application?

    The wiring diagrams are the same but the ECU's hgave different part numbers according to Yamaha. Don't care about an extra degree of ignition timing or some extra fuel, he just wants it to run.

    Thanks in advance.

    I would venture to guess that the tunes are completely different in those ECUs and are not compatible. The physical ECU may be the same, but the tunes inside them are probably very different.
