● YUMINASHI POWERSPORTS ECU
● Installing the Yuminashi Powersports ECU is really something you want to do from the first day you are buying your bike, because this easy to install and low cost upgrade will transform your bike totally!...
Installing the Powersports ECU on a OG MSX/GROM is really child splay because the Powersports ECU has been specifically developed for the OG MSX/GROM125.
This means that with this ECU you won't need to repin the wires from your stock wire harness.
The install of the Yuminashi/Keihin ECU on the OG MSX/GROM125 is simply done with removing the stock ECU and replacing it with the new Yuminashi Powersports ECU. (If you want to install this ECU on the MSX/GROM125 SF or 2019 CRF110F PGM-FI, then please follow the repin guide below)...
● Once you installed the ECU there are 3 things you need to keep in mind:
※ Installing the Yuminashi 4th gear sports sprockets LINK would be the cherry on the cake in combination with the Powersports ECU.
※ If you have no wideband O2 gauge installed, or you simply have no experience with PGM-FI tuning, then a simple rule of thumb is that if your engine don't want to make RPM's, your injector size is too large, if your engine want to make RPM's, but have bad low and middle RPM power, then your throttle body size is too large...
Both situations are too avoid, and if the injector size isn't right or the throttle body isn't right, then the Yuminashi Powersports ECU can't generate a correct map for it....
※ We recommend to install the right size injector in combination with the Powersports ECU which we have available with 140cc, 150cc, 160cc, 170cc, 180cc, 190cc, 200cc/min and even more flow rates.

● THIS VERSION OF THE POWERSPORTS ECU IS MENTIONED TO BE INSTALLED ON:
※ This ECU is a replacement for OEM #38770-K26-901
※ Keep in mind that this ECU was designed for the OG MSX/GROM125, not for the MSX/GROM SF or Z125 Monkey, so if you install the Powersports ECU on a MSX125 SF, GROM125 SF or Z125 Monkey, then this is on your own responsibility and you will need to repin the stock wire harness.
※ All ECU's are tested before shipping out to be sure all ECU's are functioning properly before shipping them out. If you decide to repin the ECU, then keep in mind that this is 100% on your own full responsibility since Yuminashi can't check how well you have executed this task.
