This is so weird, when I load their configuration file, it’s perfect. But then, when I try to tune it myself, it just utterly breaks… https://f1tenth.readthedocs.io/en/stable/getting_started/firmware/firmware_vesc.html

I watched the above video, and followed their steps, entering the right values, and the RC car drives like butter.
