It's a kunteng KT40 12MOSFET controller with LCD3.
After shunt mod and beefing up traces it works quite punchy, up to 85A (originally it was rated 30A cont 60A max) but dificult to find the throttle position to keep a low speed gently as expected. The reation to the throtle are too twitchy in the beginning of the throttle twist.
The throttle is a cheap wuxing half twist throttle with hall sensor and magnet.
are there any tricks to regain the low-power sensitivity?
