    Anyone uses microtech lt4 for ultra250x?

    Hi, at the moment i have learned only about motec and axis ecu for ultra 250. Now i have seen microtech lt4 used for ultra but i can't find also in its site the information i want.

    Anyone has used it for ultra sc?
    I know you need to change wireharness.
    But what are main features aviable? What can i modified? Can i mod timing or only fuel to injectors? Has it got launch control or other spec?

    I need some info more please. And a comparison of what has or not towards motec.

    Here a link to site spec , maybe someone with more skill can understand

    dude you must not have read the description.. it's a fuel only computer.. all it is doing is controlling fuel. no launch control none of that stuff....

    like its been said before either spend the money and get the motec or just buy a prebuilt boat.

    for what you would spend on piecing that together... you could get a motec and be done with it. motec has a proven watercraft set-up. the ecu's you have listed have no proven watercraft set-up and are developed for rotary powered vehicles... even if they could load a base map into it for you, you'd still have to find someone to tune it for you.

    Daniel, what are your goals with your boat? What are you trying to accomplish? To date, what have you done with your Ultra?
    I see a TON of posts by you asking from Pullies, to Turbo's? Which one is it going to be? You cant do both! (well I suppose you can LOL)..
    Anyways, I think you ask a lot of irrelivent questions to YOUR build.
    Do you race? or are you a rec rider?

    I agree with Dubz, Dan what have you done with your ski? You have been a part of some technical conversations on this forum. Has any of the information been used?
