I think nobody has built one yet, at least I haven't seen any installations documented on Ecomodder. That LCD display also has alarm output which could control a relay instead of buzzer. Alarm output is somewhat programmable and will trigger on different temp readings (motor, battery and/or controller) and low SOC reading.
My heatsink is pretty similar to jyanof's. I found it from metal recycler.
whats throttle vs raw throttle. And can you repeat what i need to change to make it so 0 throttle corresponds to not pushing on the pedal
Throttle is calculated throttle value which includes those t-pwm-gain, t-pos-gain, c-rr and pwm things. This calculation has max value and you are getting the max reading when you floor the throttle.
Raw throttle is what it says, raw potbox reading.
Like alvin mentioned, 718 is your zero throttle position. You could set the limit to 710 instead of 683. You've left a good play there. In your case the value lowers when you move the pedal towards the floor. Full throttle at 416 means you should set limit to 420. Or something close to that. Now your limit is at 413 which you will never reach.
All this will likely make no difference to your acceleration but at least you get 100% full throttle and not 99%. You will also avoid high pedal lockout during startup.
My car is pretty close to 2000lbs and I run 144V/90Ah lithium pack. Even at 96V/90Ah acceleration was fine. I rarely use first gear. I won't believe your ADC 8" is not enough of motor. Maybe your batteries are getting tired or you have a loose/corroded connection somewhere? Has it always been like that slow? Voltage readings from batteries during acceleration would be cool but maybe hard to obtain.
