ECUType / EMERALDK3-K6-M3D


EMERALD K3, K6 & M3D ECUs


Compatibility


  • Emerald M3D
  • Emerald k3
  • Emerald K6


Configuration


The Emerald K3, K6, and M3D ECUs output data at 19200bps.


Connections


Please note that on the Emerald the serial connections are NOT ON STANDARD PINS, the Emerald ECU uses pins 8 and 9. Race Technology understand that EMERALD supply a cable that switch over these pins with the ECU, if you are unable to locate this lead then please contact Emerald for a replacement.

Pin Number Connection Comments
1 CAN_H CAN bus interface
2 CAN_L CAN bus interface
3 - Not used
4 - Not used
5 earth Signal earth
6 - Not Used
7 Rx RS232 serial interface, data receive
8 Tx RS232 serial interface, data transmit
9 CTS RS232 serial interface, clear to send


Data Channel Listing


When connected to the Race Technology ECU Serial Interface, the following channels are decoded:
