This extension does a simple calculation of the TPS adjustments necessary for a given datalog. 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.

Note that with ECMLink installed in your ECU, throttle position data is always captured so you do not have to manually add anything to the captured values list. V2 users will simply need to check the ECU→Captured values dialog to make sure ThrotPos is logged.

Once you have a log with this data, simply right click in the log 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…

After this adjustment has been done properly, you can optionally enable the “Simulate idle switch” checkbox so simulate idle switch operation based on throttle position.
