MoTeC MDC2 16 Appendices
Appendix D – ECU Communications
The MDC2 communicates with the factory ECU or a MoTeC M800 ECU using the main CAN bus.
When used in conjunction with an M800 ECU the MDC2 controls the thermo fan, the tacho and the dash
temperature gauge based on data received from the M800.
The M800 must be correctly configured to transmit all the required channels:
• Throttle position for diff control
• Engine efficiency for diff control (optional)
• Engine temperature for dashboard temperature gauge
• Fan duty for thermo fan control
• ECU temperature for thermo fan control (to cool the under bonnet ECU)
• RPM for dashboard tacho
The MoTeC supplied EVO-X M800 configuration has the appropriate channels and communications
preconfigured for the MDC2. This M800 configuration is also preconfigured to receive several channels from the
M800 for logging or control purposes.
