 Product Description

buying-2-discount-300pxl-.png● YUMINASHI POWERSPORTS ECU FOR CBR250R (2011 / 2012 / 2013 / 2014)

● The CBR250R is a great bike, and most of the CBR250R owners who contacted us in the past really enjoy their bike, but would like to see after a while some more power out of it, and this is exactly what we have worked out with the Yuminashi Powersports ECU for the 2011-2015 CBR250R.

● A totally new powerful base map has been created with totally different fuel and ignition angles which is very noticeable from the mid range until the high RPM zone.
This area is normally the area where the stock bike struggles the most.

● Installing this ECU is really child's play because you simply remove the stock/original ECU, and replace it with the Yuminashi Powersports ECU.

● Once you installed the ECU you need to keep in mind that:

  1. 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.

  2. If you run a big bore kit on your CBR250R, then you need to install a larger injector to compensate since the stock injector has it limits.  

※ If you go big bore and you have no wideband O2 gauge installed, then a simple rule of thumb to select the correct injector 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....
