ECU Setup


  • Select either CAN1 or CAN2

  • Set Enable to ON
  • Set CAN Address = 1250
  • Select required DATA Set;  Predefined or custom
  • Set Direction to transmit
  • Set Addressing to sequential
  • Set required Transmit Rate. CAUTION. Do NOT set to high as this will limit the available bandwidth to other devices on the bus



Racepak Setup


A default RacePak Config file has be created to match the Emtron  ECU Predefined1 DATA set. This is called Emtron_Predefined1_IQ3_Config.rcg. This should be programmed into the ECU.
