Tuning PID Settings

Tuning PID Settings

  1. Set all Proportional, Integral and Derivative to zero

  2. Bring up the Proportional in increments of 5% until you see a small oscillation in the cam timing. Note: the cam timing will not reach the target cam timing with only the Proportional part of the controller being used.

  3. Bring up the Integral in increments of 5% until you cancel out the oscillation in the cam timing. When the Integral part is introduced the cam timing will go to the target.

  4. The Derivative term can be used to reduce any overshoot of the conroller, but if this does not yield any benefit, the Derivative term should remain at zero.
