4 CONNECTING THE M1 ECU TO THE PC
Important: If, during installation or application start-up, you are prompted to allow the M1
software to make changes to your PC, always allow; otherwise PC
communications will not work.
The MoTeC M1 ECU uses an Ethernet connection for communication between the ECU and M1
Tune. This ECU to PC connection uses a standard Ethernet cable, wiring and protocols.
When producing M1 wiring, all Ethernet communications cables must comply with Category 5
cable specifications. This includes wiring used to connect to the M1 ECU connector. MoTeC
have panel mount category 5 Ethernet cables available that are suitable for this application.
Note: It is recommended that Ethernet cables are wired as crossover from the ECU to
the loom side socket. By doing this, a standard (non crossover) Ethernet cable can
then be used for all communications between the ECU and the PC.
4.1 PIN-OUT INFORMATION FOR ECU COMMUNICATIONS
All M1 ECU to PC communications take place using the standard IPV6
communications protocol via an Ethernet cable.
The Ethernet connector pin-out is shown in the following table.
Pin Function
1 Ethernet RX +
2 Ethernet RX -
3 Ethernet TX +
6 Ethernet TX -
