Pedal TPS

The TPS selection is forced on. The electronic pedal signal is wired to the TPS input so that the calibration feature and TPS graph can be utilised. This signal is only conected to the TxW and it must not be used for the ECU etc. It is an indication to the firmware what the driver requires and it could be modified in relation to actual throttle movement. This mean the pedal could be 50% depression but the actual throttle opening could be 35%. This will have the ECU reacting on false information regarding throttle opening.

Calibration of the TPS.

Once wiring and connections are done, and the maximum duty power in previous step is set, then you may proceed to calibration. Click on the calibrate tab next to the TPS signal and then on the Calibrate tab in the calibration window. 

Calibration is done by stepping on the pedal and releasing it. The min and max values will be populated in two positions in the calibration window.

Now press the Save button and the Orion2 will do an automatic calibration of the throttle. It will open the throttle completely and take a reading. Then close it completely and take another reading. Then switch power off and take a reading of the rest position. It happens in half second intervals but you should see the action as it happens. The throttle TPS is now also calibrated but the throttle control power still needs to be setup. This is described further in the manual. If you are not sure on TPS calibration, then see the ECU manual for calibration procedure.

Click on the Map save button to save your calibration values at this stage.
