Description

● 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 since you can run much higher RPM's and it adjust it's map while you are driving!...

● Installing the Powersports ECU is really child's play because the Powersports ECU has been developed for the 33-pin connector from the MSX/GROM125, Z125 MONKEY and the models listed below.
This means that with this ECU you won't need to pull out any wires from your stock wire harness as would be needed to make the ECU from a CBR150R or any other bike match with your stock wire harness.

● The install of the Yuminashi/Keihin ECU is simply done with removing the stock ECU and replacing it with the new Yuminashi Powersports ECU.

※ Keep in mind that once you installed this specific ECU on the European Innova 125i there will be a charging problem, so you need to recover the red positive wire from the regulator, and connect it to the battery for direct charging, without going through the ECU to solve this issue!...

● Once you installed the ECU there are 3 other things you need to keep in mind:

There is a chance that your bike won't be spot on from the first time you start your bike since it's capable of self adjusting fuel trims and ignition tables while you ride to deliver an accurate and safe performance, it is a completely autonomous system....no more software updates, data cables, laptops, secondary sensors, building/searching or asking for maps needed.
It will automatically learn and store the adjusted fuel trims and ignition tables by itself using the OEM O2 sensor already on the engine.
So keep in mind that the first kilometers/miles you drive your bike/ECU will be in learning mode.
If you are running a big bore kit with a 2 valve or 4 valve head you will need to install a larger injector to compensate as the stock injector has its limits, and be aware that once this ECU is running completely at the programmed numbers above the 75% throttle position, so installing the correct power injector is very important to run full throttle.
The Powersports ECU has the RPM limiter removed, which means that you won't see the RPM limit anymore at 9500RPM's
We recommend to install our double valve springs set to avoid floating valves in the higher RPM zone. LINK

※ If you have no wideband O2 gauge installed, or you simply you 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....

● THIS VERSION OF THE POWERSPORTS ECU IS MENTIONED TO BE INSTALLED ON:

HONDA:

BIZ 125 ( -2012)
INNOVA 125 (2007 - 2012)

※ If you install a larger cylinder, camshaft, injector, exhaust or air filter, then the ECU will be adjusted after a approximal 1 hour drive, the ECU doesn't reset manually.
