Kp and Ki are the gains in the PI controller. Kp for the proportional part and Ki for the integral part. Increasing Ki will eliminate the steady-state error and increasing Kp will make the response faster but can also increase oscillations and overshoot. You can read about how these gains are set in the VESC Tool here: https://e2e.ti.com/blogs_/b/industrial_strength/archive/2015/07/20/teaching-your-pi-controller-to-behave-part-ii
