Hello everyone i am right now asking if anyone can help me fix my em100 gtr controller. So the other day i have installed a 20 inch hub motor 5000watt 60v to my controller and the battery of 60v 33ah and soon to be 72v 33ah, i got this minor issue with the trotthle.. so everything is fine, the motor it's been running well.. but the problem is that when i suddenly full trotthle my bike the motor will not spin, and when i am riding and then i full trotthle my bike it suddenly stop sending power to the hub.. nothings turns off but just dont send anymore power to the hub.. i have already self learned the hub and it changed a lot on power and on speed etc but the throttle problem is really an issue.. trotthle wirings are fine just checked it.. or maybe it is on the tune? But the other problem is i dont know how to tune the em100 or any other controller so i was hopping if anyone could reach me and land me a hand to do so please help will be much appreciated
