  • Page 14: Heater Control And Sensor Calibration

    For maximum sensor life the ECU should control heater start-up. It does this by communicating with the ELC over CAN Bus. For setup options see Config View -> Communications Tab -> Emtron CAN Device -> Emtron Lambda to CAN (ELC/ELCM) Setup. See Figure 5.0.

  • Page 15: Exhaust Back Pressure (Emap) Compensation

    The EMAP setting can be enabled by going to the the Config View -> Communications Tab -> Emtron CAN Device -> Emtron Lambda to CAN (ELC/ELCM) Setup and selecting the “Enable EMAP” setting to ON (Figure 6.0). Once enabled to ECU will transmit the EMAP value over the CAN Bus and the ELC will received this value so the correction can be applied.

    To confirm the ELC device has been detected, connect to the ECU using Emtune. Open the ECU Runtime menu (F3) and select the Communications Tab. Within this tab there will be a list of Emtron CAN devices the ECU has detected. It will list: 1. CAN Device Model 2.

    To confirm the ELC device has been detected, connect to the ECU using Emtune. Open the ECU Runtime menu (F3) and select the Communications Tab. Within this tab there will be a list of Emtron CAN devices the ECU has detected. It will list: 1. CAN Device Model 2.

  • Page 19: Elc Can Base Address Id Reprogramming

    To ensure each ELC device has a unique ID from the example in Figure 7.3, ELC2 Device 2 (SN 1242) needs a new Base Address of 673. This is easily done using Emtune from the Config view -> Communications Menu -> Emtron CAN Devices -> Emtron CAN Device Programming menu In this example, ELC Device 2 will need to have its Base Address re-programmed to 673.
