  • Yamaha GYTR Competition Kit ECU

    Yamaha GYTR Competition Kit ECU

    Matt in CO

    Absolutely Required for WRs!

    If you have a WR and haven't purchased this... you need to. After installing this (and doing some minor mods) my "WR350F" became a WR450F! You don't need the GYTR Power Tuner to install and use this ECU, it comes with a 0 map which is much more powerful than the restricted stock ECU. Installation requires removing the seat and popping the fuel tank up (removal not required). IMPORTANT NOTE: This is my opinion but logically it's the only way to go. There are some "uncorking" mods that need to be done when installing this ECU as it is designed for an open intake and exhaust. INTAKE MOD 1: Remove the foam from the inside of the intake shroud, this can be done without tools or solvents - just take your time and "roll" the adhesive off if necessary (helpful to be in a warm environment (or inside) ). I was able to remove 90% of the foam without breaking it apart or leaving the adhesive behind, just take your time. INTAKE MOD 2: Remove the snorkle from the bottom side of the backfire screen in the air box. This just requires a phillips head screwdriver and some pliers to crush & twist off the plastic "rivets" used to attach the snorkle to the backfire screen. EXHAUST MOD 1: Remove the silencer from the rear of the exhaust. This just requires two allen keys (3mm and 4mm I believe). Once you remove the 6 allens and end cap, remove the 4 allens and pull out the silencer and outer metal gasket. DO NOT remove the spark arrestor, the USFS requires it and you don't want to be the one who starts a forest fire! Once those are done your WR will be able to breathe and this ECU will bring it to life! If you can find someone or have the money I'd highly suggest getting the GYTR Power Tuner as well, it can make a huge difference - changing power delivery and throttle response to your riding style.

    Must have, bikes should come with this.

    This is a must have for these newer bikes. It is the "screw driver, clip position and jets" from the older bikes. After a few trial and errors I got my bike to feel "right" for me. The stock settings on my bike are strange but a few changes and it was ready to ride.

  • Wiseco Fuel Controller

    Wiseco Fuel Controller

    Do Not Waste Your Money

    Bought this controller for my YFZ450R along with the Lexx Slip-on exhaust. Could not get the adjustment I needed. Ive tried every setting imaginable and even got settings from Wiseco and other manufacturers with similar Dobeck 3 button controllers. No luck. Also if you buy this controller just know that it is not returnable once mounted. Very unfortunate waste of $200. If you have a fuel injected YFZ year 14+ do not buy this controller. Do your research and buy a Vortex.

    Runs so much better

    I put it on my 2016 husqvarna fe350s. It made a huge difference! I wasn't able to find a dealer to remap my ecu and this was the least expensive option to get the thing running richer. A lot of mixed information on the internet about the jd tuner, for my application it did exactly what i was hoping. If you have a 350 thats a DOT model, i highly recommend this tuner!

    slight change

    2015 KTM 200 did notice a very slight change in the map on mild and dampened the power delivery a tad. Might be helpful in super tight woods or some slippery conditions to lessen over-rev. It works ok and better than not having an option at all. I would recommend just don't a expect drastic cut in power delivery

    Very limited to programs on this fuel controller

    The program that is offered on this really does nothing but you will lose 500 RPM with this as soon as you upload the program. Working with the company to fix the program is like playing cat and mouse. I would spend a little with extra and go with something else. Works good as a display and shows you what your motor is doing but that's about it and i believe to can buy that one just for that which is cheaper.
