I just got my setup running 21s powering a crown 4080 motor. the programmer is simple. All you need to do is correctly wire the TX/RX/GND from the plug to a FTDI chip. I did have issues with the voltage settings. I started on a partial charge and found that I had to set the system voltage to 72v in order to clear the voltage scaling fault. We should be able to change the pu. setpoint, but I couldn't figure out how just yet. This also became an issue when fully charged again. I had to raise over voltage setpoints to around 130% to get both the flags and faults to clear. For the brake I ended up having to pull brake one to 5v and leave brake 2 open ended. I plan to use proportional regen, but haven't had time to get to that yet.
With 19" motorcycle wheels and tires, I was able to get to 44mph so far without flux weakening. I haven't seen current rise above 47 amps yet though. With just hubsinks and no ferrofluid, the motor temps can quickly rise to 70c after a good speed run, or constant heavy throttle stop and go action. I will probably take the cover off tonight and add ferrofluid. After that I may see why I am not seeing higher current, and how well flux weakening works.
You can use the phaserunner software for most operations, but it is much more restrictive than bacdoor.
