    magnum tuning rev limiter

    Anyone ever tried it? Did you make past 66,000rmps?
    Lady swear to me ot works. I cant even get tec support on product.

    from their web site it involves opening up the ecu. good luck with the potting compound. unsoldering one of the quartz chips and soldering on magnum tunings rev limiter box's wires. then plugging in a pill like those used in msd boxes to set rev limiter. also gets a positive and a ground.

    i don't have one or never seen one so i don't know but should work if the crystal replacing is actually the one for the rev limiter. but i doubt it. rev limiter should be stored in the eprom with the fuel and ignition tables. and now with added revability how are you going to account for timing curve and fuel above the stock rev limit.

    AEM has a piggyback that might work for fuel and ignition?

    I want you guy's to read this very carefully about the F12 NA! That ecm or ecu revs up to 7750 RPM. That's the ecm or ecu that i am going to put in my F12-X ski this winter.2007 Honda AquaTrax F-12X/F-12 Features - Honda.com

    Interesting? Have you changed the valve springs?

    I had though of that but the forced induction X ecu will be very different then the NA?

    You would need to see what exactly is different like injector size for example.

    All the safety which keeps the engine from being ruined is VERY good on the X 3D mapped ECU.

    I will start off with the ecu and wire harness from 05 through 07 F12 NA and a manual boost control valve. As for the AFR i have a gauge on the ski if it need's bigger injector i wil get them. I am just worried about the Timing. Go to my build page.Stopped by Jake Speed's today...

    Oh you changed the hull to help in more speed?

    I pretty sure the injector size is different on the NA engine. Also no maps for boost in an NA. You need a piggy back ECU like what AEM has.

    Yea i pick up about 3 mph on the hull with stock motor 64 to 65 then after putting more boost 67. With a Turbosmart fuel cut defender.
