EML-4 CAN Setup

EML-4 Setup. 

Up the 3x EML-4 may be connected to the Emtron CAN bus.  This allows the lambda data for up to 12 cylinders to be connected to the ECU. With the addition of every EML-4 module the CAN address for each data packet MUST use sequential addressing. The preferred addresses are listed below.

  • EML-4  

    • CAN Data Address  = 65
    • CAN Status Address  = 66

  • EML-4  

    • CAN Data Address  = 67
    • CAN Status Address  = 68

  • EML-4  

    • CAN Data Address  = 69
    • CAN Status Address  = 70

ECU Setup.

ECU CAN Setup

  • Select an available CAN node, CAN1 or CAN 2
  • Select Baud Rate to 1Mbps
  • Turn the selected CAN channel ON
  • Select DATA Set = EML-4 (option 14)
  • Select CAN Address  = 65  (On a single installation this address MUST match the EML-4 CAN Data address. With multiply EML-4  modules connected to the BUS use the lowest address. The ECU CAN protocol in the mode uses sequential addressing and expects the received CAN address to get larger. 

NOTE: All other CAN settings are not used.

ECU Input Setup

    The Software allows each EML-4 sensor channel to be assigned to a cylinder. 

  • Select Input -> Input Pins Setup. Select the Lambda Cyls Tab
  • Select the Lambda Cyl you want to config.
  • Select the correct CAN Lambda Channel .In this example Cylinder 1 has been allocated to the LA 1 channel on the first EML-4 module.

    The 1st EML-4 assigns LA1-4, the 2nd EML-4 assigns LA 5-8, the 3rd EML-4 LA 9-12.

  • Select Predefined Calibration to Lambda NTK EML-4. Don’t select Custom. Select Clamp Lo and Clamp Hi if required.

  • The Fault Settings are not used from this form, as this operation if performed internally by the EML-4 are transferred to the ECU over CAN.
  • The Engine Limit Table is still used.
