ECU Adaptor Looms

These looms enable the C127 to connect quickly and easily to your vehicle's ECU - whether factory or aftermarket - to access important engine data for display and/or logging. Some of the common channels received are:

  • Engine RPM

  • Throttle position (engine)

  • Engine temperature

  • Manifold Absolute Pressure (MAP)

  • Inlet air temperature

  • Mass Air Flow (MAF)

  • Barometric pressure

  • Load point

  • Exhaust temperature

The loom you will need depends on the ECU in your vehicle:

OBD-II to Display Loom

Part No: #61197

The OBD-II loom is a plug-in adaptor that connects the C127 terminated loom (supplied in C127 Race Kits) to the standard, on-board diagnostics port of many modern vehicles.

This enables the C127 to display and log a selection of channels, which differs from car to car.

Vehicle compatibility will vary from region to region, but as a guide most cars built after 2007 have an OBD-II connector.

CAN ECU to Display Loom

Part No: #61198

This plug-in adaptor joins the C127 terminated loom (supplied in C127 Race Kits) to the standard MoTeC CAN communications connector used by MoTeC M84, M400, M600 or M800 ECUs. It makes 70+ ECU channels available to the C127.

This loom will also work with other manufacturers' CAN-based ECUs, with the exception that the round AMP connector must be removed and replaced with a suitable connection for the relevant ECU.

RS232 ECU to Display Loom

Part No: #61199

The RS232 ECU loom joins the C127 terminated loom (supplied in the C127 Race Kits) to the D9 RS232 communications connector used by MoTeC M4, M48 or M8 ECUs.

This loom will also allow connection to many other RS232-based aftermarket ECUs; custom communication templates may be required.

The RS232 ECU loom can provide 40+ ECU channels to the C127.
