How to configure a Motec M1 series ECU to work with a Haltech display dash




If your Haltech dash display is using or has been updated to use the NSP software, you will first need to set it up to communicate with a Motec ECU, similar to the example shown in the "Third-party ECU CAN" section of this article: Sourcing data for dashes in NSP.

Also ensure that your Haltech display dash is correctly wired to an appropriate power and ground source, and that the dash's CAN High and CAN Low pins are connected to your Motec ECU’s CAN High and CAN Low pins. The ECU CAN High and CAN Low pins are located on the ECU connector. Optionally, you can use an HT-130046 CAN adapter loom to plug the Haltech CAN High (white) and CAN Low (blue) wires into the ECU's Superseal connector. This adapter uses a DTM-4 receptacle, which plugs into the CAN cable included with the Haltech dash display. Red and black flying lead wires are fitted to supply switched +12V and ground, respectively. 

Note: Due to the Motec M1 Series having multiple CAN Bus channels, please ensure you connect the Haltech display dash to the CAN Bus selected in the steps below:
  1. Go online with your Motec M1 ECU using the M1 Tune software.
  2. Once online, navigate to the ‘All Calibrate’ worksheet.
  3. In the 'Calibrate' pane, tick the 'Setup' type to display all setup options.
  4. Browse to ECU > Transmit > CAN Bus and note the selected bus. If no bus is selected, choose an unused available bus.
  5. Browse to CAN > Bus X (where X is the bus selected in the previous step) > Mode and set this to 1 Mbps.
