| What base settings should I be running for my bike? |
You have purchased an Electronic Jet Kit. Like carb jet kits in the past, the more you modify, the more responsibility you take in getting your fuel curve right. We will support you though every step along the way and make suggestions to help you get your bike performing the way it is suppose to perform. All EJK controllers come pre-programmed for typical stage 1 modifications meaning an exhaust pipe change and air filter change. We recommend to install the product and drive your vehicle with these settings before making any adjustments. After the initial ride you should get a feel of how your bike is responding and can start fine tuning from there as necessary.
Please browse the product section to your specific vehicle to find the listed recommended settings. Go Here
Please check the tuning advice section for better info on which mode to adjust to start fine tuning. Go Here
REMEMBER THIS: You are probably not trying to win a drag race where everything needs to be perfect. There is a lot of room in tuning a vehicle to have it run just fine. Every rider is perfectly able to tune their own vehicle.

| My fuel mileage has dropped considerably. What mode should I adjust? |
Fuel mileage and achieving the best performance usually ends up being a compromise one way or the other. Most vehicles already come a little lean from the factory to achieve the best fuel mileage and to pass emissions. When you start modifying your vehicle then most of the time you lean out the fuel mixture even more. To tune your vehicle and have it operate smoothly you will end up adding fuel. Adding fuel to achieve the best performance tends to result in lower fuel mileage. In rare instances though some riders may experience an increase in fuel mileage.
The GREEN mode in EJK controllers has the largest affect on the fuel mileage. The GREEN mode adjusts the cruising fuel where most riders spend the majority of their time running under this condition. Lower your GREEN mode light setting half a light and compare your fuel mileage results.

| I'm experiencing popping. What can I adjust on my EJK controller? |
Popping issues should always start with an inspection of your exhaust system for air leaks first and then consider fuel tuning adjustments. The problem normally is AIR getting into the exhaust system. By adding more fuel you can see a reduction in backfiring (popping) but that isn't fixing the problem and it usually results in drivability and/or mileage issues. It is always best to eliminate the cause (AIR) rather than changing the effect by adding more fuel.
Typically, the mode to adjust on EJK controllers for popping issues is the YELLOW mode. Some applications have a de-accelerating fueling mode which can be adjusted to help cure decel popping. If the decel mode is not present, then try adjusting the YELLOW mode up 1 light setting and note the results. If things do not change or get worse then try lowering the setting. If you continue to experience problems then please navigate to your vehicle in the product section and check for advanced troubleshooting notes. Please feel free to contact us if the problem persists.

| How do I determine if I have a GEN 3 or GEN 3.5 controller? |
On the label of the EJK controller, just below the 8 LEDs, you should see the description stating whether the controller is a GEN 3 or a GEN 3.5. In the case of where potentially the controller was mislabeled then inspect the following:
GEN 3 controllers will have a black rubber plug on the back of the unit. This plug covers the programming port for the controller. Also the RED power wire is several locations away from the BLACK ground wire.
GEN 3.5 controllers will have the RED power wire and BLACK ground wire directly next to each other coming out of the controller.
