    R&D Powershot Fuel computer

    Anyone got any feedback on this?
    http://www.rd-performance.com/catalo...%20Controllers

    Thinking of adding it to our near stock ski - hoping to get some intial performance boost and ensure there is always enough fuel for other mods (RR SC impeller....)

    What do you guys think?

    Always enough fuel for other mods
    how do they expect to pull that off without bigger injectors?

    I have talked to some fuel injection experts and they all say the same thing, that box is garbage!

    They claim to stretch the injectors firing pulse to provide more fuel...

    The injectors will eventually run out of duty cycle!

    Need more fuel? Simply install 42# injectors. Need even more fuel than that then you can jump to 50's and then use a real fuel controller to custom map it.

    My concern with the injector route would be that it seems to lack adjustability - i dont know how far my modifications could go (cash and reliability concerns)

    How much scope is there with the stock injectors?

    Stock injectors will fuel a stage 2

    Add more boost to the stage 2 with the RR SC impeller or Riva stage 3 supercharger and you add 42# injectors (only $200)

    Add more boost with a Rude Charger or B kit then you need 50# injectors with a fuel controller for either the stock or Rotax Racing ECU's or a Riva ECU as its mapped to run with the 50# injectors so there is no need for a fuel controller.

    that deal looks like it belongs on my Christmas tree.. I bet it works as well too. LOL


    dont cut corners on fuel control you will be sorry. One problem a DIY will find out real quick is ...they have no way of recording the changes..
