| To use this function, just grab a log with throttle position data (TPSVolts or ThrotPos) ranging from fully closed (foot completely off the throttle) to fully open (foot to the floor). The engine does **not** have to be running to capture this data. | To use this function, just grab a log with throttle position data (TPSVolts or ThrotPos) ranging from fully closed (foot completely off the throttle) to fully open (foot to the floor).

| Once you have a log with this data, simply right click in the log (graph screen) and select "TPS Adjust". You'll be presented with a tab showing the suggested new values for TPS adjustment. Review this data to make sure it seems reasonable before you hit Save to ECU... | Once you have a log with this data, simply right click in the log (graph screen) and select "TPS Adjust".

Doing so makes the ECU ignore what the physical idle switch pin coming into the ECU indicates and instead simulates the value based on throttle position. This also frees the idle switch input pin to the ECU for other purposes, such as switching in auxiliary timing/fuel maps and/or secondary fuel adjustments (dual banks or dual fuel types). |
