My new build is a 10T MAC motor with a 12fet 50 amp controller running at 44V, the problem is, the takeoff from a standing start is a bit brutal. The MAC is renowned for it's ability to chow down on amps but it's really quite annoying that unless you really gently rotate the throttle it will lurch forward trying to throw you off the back, I've got a 30A limit set on the CA but that only kicks in quater of a second after takeoff to choke the power which can cause even more jerkyness. The controller is currently factory standard but I plan to use the USB cable to set a 30A limit on the controller itself rather than using the CA to limit the power.
So my question is this? is there anyway to ramp the throttle up over time? or otherwise smooth out the throttle response so if I give it 80% throttle in an instant, it actually goes from 0% throttle to 80% throttle over 1-2 seconds to stop the "bite" and behave a bit more like a clutch on a car easing in the power. I don't really want to set a lower limit on the controller itself as I need all those amps for climbing the big hills, the 3 speed switch helps a little bit as it stops the launch being so ferocious but it's a speed limit not an amp limit. Anyone have any experience in this?
