Product Description
This listing is NOT for the ECU part! Please watch our detailed video on this subject, showing all steps required.
This listing offers a software update for the Engine Control Unit (ECU) of your 2017 - 2022 Royal Enfield Himalayan. You can do it as a preventive measure, to enhance overall engine performance, or to address commonly reported concerns with fluctuating RPM, stalling, and poor performance at various operating temperatures.
We make it simple! After purchasing the update, remove the ECU from the bike and ship it to us. The ECU is easily accessible from under the seat. We will update the software and test the ECU’s operation before sending it to you. The cost of shipping to you is included in the listed price. You will pay for the shipping to us. We will complete the software update and ship your ECU within two business days after we receive it.
Please note that on some models, you must manually adjust the idle mixture screw after installing the ECU with updated software. This can be done by removing both hex bolts holding the fuel tank to the frame, lifting the tank, and the brass round flat head mixture screw will be visible on top of the throttle body. Adjust the idle using a short flathead screwdriver by checking the RPM gauge at the speedometer. This procedure must be done when the engine is completely cold for better results. Fine tuning may be needed after the test ride at operating temperature.
