Boost control e-wastegate

You must check the log to see the actual duty cycle on the output.

Every run has a 10% duty cycle when building a boost.

  1. The actuator duty cycle is 10%.
  2. The actuator DC is calculated from the control value, which is 0%.
  3. Control is 0% because the boost state is “Above pressure max”.
  4. Boost pressure at that point is 111 kPa g.
  5. Maximum boost pressure is set to 80 kPa g. Above that control value is set to 0% to open the wastegate fully.

You can’t just swap values in the base table to invert PWM because the boost logic assumes control 0% is the gate fully open and control 100% is the gate fully closed.

You have to enable the “Invert output” option for the actuator.
