    Unhappy serious issues with Seadoo 2011 RXT-X PLEASE HELP!!!!

    The Anthena ECU is acting up! The fuel pressure regulator is set to a static pressure of 65psi and fluctuates and causes the gas gauge to read full all the time? sometimes half a tank, etc. Fouls up the plugs and not hitting top speed. The ski has a stage II kit and 17 hours.
    error code showed up and went away--- gas gauge module error!!!!! WTF....


    We are reflashing the ECU and reseting the defaults. Bad fuel pressure regulator? any ideas?

    Jet ski is supposed to be hitting 74-75mph.

    Welcome aboard the Hulk...
    I don't have an answer for you but I'm sure some of the experts on the Athena will speak up soon.

    I know there are a few guys on here that have experience with it.
    Like Duke and unsane..

    1 of you guys should pm Duke.

    He's got experience on the Athena.
    When you mod a ski It's sometimes a pain in the ASS tuning it.

    There is a thread started by riva crew about adjusting idle. You can pose questions to them there IMO.

    We found 65psi to be way too much fuel pressure. I'm backed off to 58 now, but I'm still running rich.
