    more WOT analysis

    I take it with humor - but it seems I am still nailed with a Speedlimiter
    My fuel tank was full and the VTS System in neutral (middle), and I am riding alone at all runs ha ha..

    It appears you still have torque limiting active.

    Your WOT stuff needs to be leaned out about 6%

    is also the ign get retard back .....waht fuel you use ?

    OK you need to remove fuel!
    Your way to rich and the kills the power.
    Reduce fueling on top to maybe 12.5 afr.
    You have moderate igntion so i think that will be safe

    But what fuel quality do you use?

    Also, You have an issue with the gas pedal lever.
    It dont go to 100 % and then throttle dont open fully.

    Look in your log in excel. or megalog , you see sometimes gas pedal only request 98.5 % and then throttle 95 %.
    I assume you want 100 % opening?

    I can also recalibrate this in the file if you send me the file name you work with,. but then you and jesus need to redo your mods.
    You can also take apart the handle and see if you can adjust it.

    Or order the RIVA gas pedal thing.

    Just had a look at your log and your throttle is not at 100% open.

    This maybe part of the problem.

    Your ignition on MRG file is around 33 to 33.75 degrees on all cylinders most of the time.
    You get SOME engine noise/retard on cylinder 2 mainly, so keep an eye on this. Its small amount, but maybe be sure that all injectors are EXTREMELY clean when you were handling them. Cylinder 2 is not typical "too agressive" tuning. It could also be rpm control as its not 100% throttle and you are getting close to intended rpm limit.

    If you reduce your fuel around 5% in WOT area and also try get 100% throttle actuation, and I would try this with the 15/20 prop maybe. or add 1mm to this prop.

    You should see good speed. Sometimes also the quality of the hull and intake grate can affect top speed. Even ride plate. Looks like your mapping is very close to optimal... So once mapping is almost perfect, I would look at the hull components to make it faster.


    You are logging very good information. Congratulations on doing this properly.

    Thanks for your valuation of my logging - thanks a lot!

    My Seadoo dealer make a "Close Throttle Reset" with B.U.D.S.
    Only for get sure, we utilize all the possibilities we have.
    Before this reset the throttle open 98,8% after reset we have 99,6% with B.U.D.S.

    The injektors are new 3 hour use. Never get in contact with ethanol. Only fine quality gas.
    I am not touching the nozzles (with nothing) when installing or handling.

    I use 102 Octan gas with zero ethanol all the time.

    I order a 15/20 from Erick Speedfreaks with a setback / re-pitch 11/18.
    I like to try.

    Yes I think it is a mechanical problem - I take a look inside the handle.

    Thanks for valuating my tune!
