250/350/450/500/501 Fuel Programmer | 2017-2023 EXCF/XCFW/FE/FE-S
   These instructions and settings, are for the newest R3 programmer
If it says  R3 in the left hand corner, then you have the best performing                      and most reliable programmer on the market today. 

THE SETTINGS FOR THE PROGRAMMER, FOR THE VARIOUS BIKE MODELS AND YEARS, ARE AT THE BOTTOM OF THIS PAGE, WHERE IT SAYS "CHEAT SHEET".  THESE FIRST FEW PAGES, JUST SHOW YOU HOW TO INSTALL AND USE THE BUTTONS. PROGRAMMERS ARE DESIGNED TO BE USED WITH STOCK FUEL PRESSURE OF 50-52 PSI AND NOT LOWER PRESSURE

     This programmer is designed to stay on the bike and the easiest place to put it is inside the airbox cover. It comes with double stick velcro to make this easy

     The newest programmer has an R3 in the upper left corner.  This means it has the latest and most robust electronics.  This electronics package works best with the KTM's electronics.

     This programmer has 6 modes.

Mode 1. Green mode.  Let's you add 0-14% fuel when the bike is running with the                   green LED ON.

Mode 2. Yellow mode.  Lets you add 0-28% fuel when bike is running with the                         yellow light on

Mode 3. Red mode. Lets you add 0 - 28% fuel when bike is running with the red                     light on.

Mode 4. Green blue mode.   This is you accelerator pump adjustment.  

Mode 5. Yellow blue mode.  This is the switch to turn on the yellow mode 2

Mode 6. Red blue mode.   This is the switch to turn on the red mode 3

The 2 clips of the unit plug in between the stock injector clip and the stock injector. Unplug your clip from the injector and plug into the one coming from the unit.

Now just plug the other 2 together and you are done with this part. Run the wires inside the frame rails so they are contained.

The last step in the installation is to just secure the black wire to the battery ground cable.

     When you start the bike, the lights will come on on the left and right side of the screen. The led on the left is #1 and on the right is #8.   The lights lighting up is showing you that you have power to the unit

When you push the “mode” button in the center, you’ll notice that the lights that come on the screen change colors. First GREEN lights come on, then when you push the mode button again, to switch to the next mode, yellow lights come on, then red, then green-blue and so on. Then back to green.

This is how you switch to various areas, which can change the fueling.

A few very important things to know at this point are:

1.     We’ve spent a lot of time with the dyno and the Air/Fuel ration meter, and real world riding, to make sure the base software in the unit is in the perfect starting position to give you the best results.
 

​2.     This unit cover various models and the final "mode" settings are how you adapt it from one model or year to another.         The final mode, or LED settings, fine tune the amount of fuel added, from our well written base program.  So it's best            just to follow, or be close to the area of the recommended settings

     Push the mode button once and the green light comes on. when light 1 is on, there is no fuel added and when light 8 is on, there is 14% fuel added. 

    So each full light move to the right ( push + button ) adds 2% fuel and each half move ( say for example light 2 and 3 lit ) adds 1% fuel.

     Follow the setting ideas on the cheat sheet at the bottom of this page, as all years are different.

    On 2020-23 bikes with Oxygen sensors in the headpipe, no fuel will be added in this green low rpm zone until the 02 sensor is removed.  Ironically, the 02 delete plug adds the needed fuel, and you don't need to add any fuel in this green mode.

    Now to the yellow blue zone.  This is the RPM based switch point, to turn on the yellow circuit.  We suggest LED 2 on many applications, because this turns the yellow ( more fuel added than the green zone ) on at 6000 rpm.

    If you were to move this led to the right to LED 5 lit up, there is a chance the yellow zone would never come on.  Moving to the right raises the RPM that the yellow zone comes on.  

    Our pre determined settings here are key to a strong running bike.

     Now comes the accelerator pump circuit.  Push the mode button one more time and the green blue come up. This is the adjustable accelerator pump circuit.

    This is proprietary to us and no one else has this.   It's pretty well set at the 4 and 5 led lit up.  If you move to the right with the + button, you get more fuel during the accelerator pump squirt.  Move to the left with the - button and you get less fuel.

    You are welcome to experiment with this, to get the desired instant response you are looking for

    Push the mode button one more time and the red LED comes on.  This is the exact same scenario as the yellow led, but the red zone add fuel at the very top end of the RPM range.

    

     Push the mode button one more time and you go into the yellow led. The yellow mode is designed to add fuel into the mid range portion of the rpm's.

    This lets you add more fuel, when it is needed, to get that strong pull through the mid range.  Then you will transfer into the next mode, the red mode.

    Moving the the LED setting to the right, with the + button, adds fuel and to the left with the - button, removes fuel.

    You need to make sure the yellow zone is turning on at the right time ( rpm ) so it even comes into effect

       When you first start the bike, The lights will come on on both sides.  This means there is power getting to the programmer and it is working

    The red blue mode does the same thing as the yellow blue.  It sets the rpm at which the red zone turns on.   This is something it's better to use our suggestions.  

    For example, our settings on a 2021 500 excf with open exhaust and open intake ( reeds out of intake tract ) say set this at LED #2.   This is because this turns on the red zone at 8000 rpm until 11,000 rpm.  This, along with the right yellow zone turn on rpm, makes a flat air fuel curve when you get on the gas.  This makes sure all areas are doing their job and you have a nice flat fuel curve.

    This makes for a strong pulling bike.

Fuel Programmer Instruction Cheat Sheet

These settings are for the programmer that has the  R3

written in the upper left corner.

If it doesn't have that on it, then you have an older one. Then add 2 lights to the plus side, on the yellow and red settings.   So 6 would be 8 for you, as an example

For Euro spec and Aus spec bikes, we don’t get to test with them specically , so just take feedback from
happy customers. So basically nd your bike on this list from above , and start settings 1-2 settings leaner
than the USA spec settings. You can play from there
