One you have configured the sensors, and confirmed that in manual mode, the throttle plate moves correctly (ie a positive drive duty percent opens it, a negative drive duty closes it) its now time to calibrate the PID. Set the throttle mode to closed loop. The below default PIDs should be used. If you find the throttle overshoots the pedal (or the plate oscillates) try reducing the P value. PID tuning should usually be left to your tuner, or, you can load the settings we have on file for various throttle types. We can also assist remotely with PID tuning of throttle plates.


The Main TPS and PPS should be set - usually this is sensor 1 in each case, as the below illustrates.


Note that the TPPS and PPS Max Error are the acceptable error margins (1-10, 1 being any amount of difference is OK, and 10 being that the sensors must align perfectly). If you have a sensor failure, the Failsafe PWM % will be driven to the DBW Motor. You can experiment with the failsafe numbers by disconnecting one of the sensor channels on either the TPPS or PPS and check that the system "notices" and correctly acts upon it.


If failsafe occurs during normal pedal sweeping after correct calibration (as denoted by the DBW Sensor Status DROs) then the Max Err should be raised, and the ECU power cycled.
