I have something very strange. My engine runs very slowly in pass mode, even at full throttle. In walk mode the motor runs normally. When I connect the learning wires the motor also runs very slowly but if I go to settings P20 with the learning wire connected, I can run the motor quickly at P20 1,2,3 at 0 the motor turns slowly again. When I save the settings at P20 1,2,3, the motor runs normally but this is not usable. I probably did something wrong with the settings, but because the manual is so unclear I tried just about everything to make the controller work, probably with bad results. There are no error codes. Hopefully someone has a solution
