Yuminashi Racing ECU for Honda MSX JC61 from 2013

Replaces OEM part number #38770-K26-901

Once you have installed the ECU, there are 3 things you should keep in mind:

- There is a chance that your bike will not work properly the first time you start it: The ECU is capable of adjusting the fuel settings and ignition tables itself as you ride to provide accurate and safe performance, it is a completely autonomous system.
It automatically learns and stores fuel settings and ignition tables in a closed loop using the original O2 sensor already installed on the engine.
-The first few miles you ride, your bike/ECU will be in learning mode. Ride in a normal way, on your own and varying the rpm under load (below 80% throttle opening) and without excessive high rpm.

-If you are using a larger bore kit and/or a higher performance cylinder head, then you must install a larger injector to compensate, as the stock injector has its limits.

-The Yuminashi ECU removes the rev limiter at 9500 rpm.

-We recommend installing our dual valve spring set to avoid the worry of valve flutter at high rpm.

Not suitable for MSX125 SF / GROM125 SF and Monkey 125cc JB02-JB03
