ECU getting into the factory ecu to change air fuel ratio??? CO mode.
Hey All, I am new to the forum. I have been reading lots of good stuff here... I just bought a 2011 Stryker. One of my changes is adding the V and H slash cut exhaust. I did the resistor mod to the negative lead on the 02 sensor. The bike is still lean when coming off of closed throttle. I spoke with a Yamaha tech and he gave me just enough info on how to adjust the ECU in the co mode to peak my interest. He indicated that there is no need to add a fuel controller to richen up the mixture. Says I can do it myself by getting into the CO mode and just changing the settings.
Any Help?? Has anyone done this on a stryker??
