Analog sensors are the 0-5v and resistive based sensors that give the ME ECU its information required for both fuelling and other logging functions.


These include Manifold Pressure, Throttle Position, Lambda, Oil Pressure sensors, as well as temperature sensors such as coolant, oil and intake air temperature.


You will need to wire them to your ECU, (note Plug-Ins will already be routed correctly where applicable, and our factory basemaps will already have the channels and calibration curves correctly assigned) and then assign the chosen sensors to the channels, then finally calibrate and confirm the readings are correct from within MEITE.


The setup steps for analog sensors are as follows:

  1. Wire the sensors to the ECU as required. Note you should use Ana Vx inputs for voltage outputting sensors like MAP, TPS, pressure and Lambda sensors, and Ana Tx for thermistors such as coolant, air and oil temperature.
  2. Assign the sensors to the correct channels in the Analog Settings.
  3. Calibrate the HRTs for each sensor such that the sensors report correctly in MEITE.


All of this is viewable from one tab within MEITE, the “Sensor Cals” screen, as pictured below:

When checking sensors, start at the most basic and work your way from there. For example, the first reading to check is the battery voltage. In the image above we have our test ECU imply powered on the bench, and yes, with the ignition on, we are seeing 12.3 Volts - perfectly normal. We may see this reading drop to around 8 or 9 volts during cranking, again, normal. And running, with the alternator working as it should, we would hope for 13-14 volts.
