Another small update, I got the motor temp working....sort of. It looks to be pretty inacurrate and it looks like the coeff for it is unprogrammable. Chucked it onto the display, will see what it does. I also worked out the current and watts readout from the controller. They were a bit tricky to spot because they are essentially negative when drawing power and positive when regen is flowing back into the battery. Also chucked those onto the screen.
I havent played around with the regen much, mostly because it doesnt really work properly as engine braking. Tends to hang and not re- accelerate when giving more throttle. I though I could make my own version of it by simply reading the throttle ADC and applying the low brake signal when I have > 0 rpm on the motor and my throttle is closed but I dont think that will work either because from some testing it looks like if you activate the low brake, bring the throttle on and then release the brake, the controller wont come out of braking until the throttle is lowered back to 0%....Ill think about it some more.
Does anyone properly understand the difference between "stop back current" and "max back current"? The manual is a bit vague, is it something like the maximum back current is how hard the motor is braked and the stop back current is the limit of recharge into the battery? Recommends having the max setting 25-50% higher then the stop setting. I guess if the motor is generating more power then you want to put into the battery it can just shunt the windings together and heat the motor instead. I could be wrong, hopefully someone actually knows.
I didnt have the balls to try changing the current settings while riding yet. Bit worried it might just really confuse the drive and burn something out. I know from testing that I can safely change the throttle mode (eco, lin, sport) while the bike is stationary without any issues. I could try PWM on the low brake but Im pretty sure that wont work....hmm how much do I want variable regen I suppose. Anyone actually used variable regen on here and care to chime in?
