I finally got (almost) everything set up and tried the motor in real-life conditions. Runs well and pulls good if I command it to do so. I've limited battery amps to 300, current ramp rate to 20 and kp/ki set to 8 and 20 if I remember right. I'll need to check all the other values next weekend when I get to drive the car again. Values might still need more tuning. I'm using 96V/90Ah Thundersky-pack.
Controller works great. It reacts immediately to throttle pedal and feels really smooth. I connected a laptop to controller using Deltaco-branded usb-serial -adapter and used RTD Explorer for monitoring and setting all the parameters. On -15C day I managed to get heatsink temperature to -6C after driving for a while. Now I need to run that serial cable through firewall and have some driving data logged.
