Abnormal noise from E-throttle motor


Recommended Posts

Two options:

1) increase the PWM Frequency from 500Hz. You may need to change the PID settings slightly due to the higher control frequency.

2) Change "Run Throttle" to "Quiet" - it'll turn off the motor when the engine isn't running, and it will sit at its natural rest point until the engine starts.


You could also do both.
