Having difficulty with low speed off road drivability: throttle-off is abrupt, and throttle-on is even worse. No problem on pavement, or in 2nd gear off road, but when bouncing around off road in 1st gear it is really difficult to be smooth. Going to a 15 tooth front sprocket made things a lot worse, but no way am I going back to 16t. I have already re-contoured the throttle cam, that helped a little bit but the real problem is fueling- it is quick to go to fuel cut, and abrupt when the fuel starts flowing again. Do any of the fuel controllers allow you to modify the fuel cut or hang the Idle Air Control Valve open during fuel cut?
