Once you have fitted a Throttle Position Sensor, or TPS, you will need to calibrate it from within MEITE.


First, be sure you have correctly wired, and assigned the throttle sensor signal input to "TPS Raw" in the Analog Settings. The signal on the chosen pin should sweep from approximately zero to five volts as you move the throttle from fully closed to fully open. See the Throttle Sensor wiring section for information on how to connect it to the ME range of wire-in ECUs. The Plug-Ins will already have it correctly wired and assigned in the supplied base-map.

Throttle Calibration Wizard

You can use the Throttle Calibration Wizard (under ECU Tools menu) to easily calibrate your throttle. It will also automatically correct the calibration for throttles wired "backwards". (Where the voltage decreases as throttle opening increases.)

Simply start the wizard and follow the three steps below, and then the TPS HRT will be fully calibrated for you.


If you do not see the the "Throttle (Volts)" change as you sweep the throttle, please check your throttle sensor wiring.

Traditional HRT Calibration Method

You can also choose to calibrate the throttle sensor using the HRT Table for the TPS Sensor. You can access it from Entity Tree View>HRTs>TPS HRT.

Most would opt to use the wizard detailed above however.

Note If you are using a Plug-In, be sure (if applicable) that any jumper settings for TPS have been made correctly. (Refer to that model's hardware install guide.)

  1. Again, go to the “Sensor Cals” tab in MEITE.
  2. Sweep the throttle from open to closed. The TPS Raw reading should go from low to high. If it is inverted, swap the 5v and Ground wires connecting to the sensor.
  3. Note the ‘TPS Raw’ reading at both CLOSED and WIDE-OPEN throttle. In the TPS HRT image below, you can see the CLOSED reading was 6450 (0.1v), and the WIDE-OPEN reading 51200 (approx 4V). (Note you may be working in volts as units, which is normal).
  4. Enter these as shown into the TPS HRT table, using the top two rows. The remaining rows should read 65535 (or near 5v), 100, as shown.
  5. Sweep the throttle again, and you should see the yellow crosshair ‘walk’ up and down, as well as the TPS(%) readout will now go from 0-100%.
