NOTE :
To avoid signal errors and loss of accuracy, a cable of a maximum length of
1.5 m between the sensor and ELC is recommended.
CAN Bus Wiring
- CAN Bus High and Low are differential signals, so a twisted pair MUST be used. Failing to do so will compromise the entire CAN Bus System.
- In some extreme environments, a shielded twisted pair may be required to help with reliability and data integrity.
- The less connectors in any transmission system the better. Unnecessary connectors are almost guaranteed to present an impedance discontinuity and hence may cause reflections and data loss.
- CAN Bus termination must be done correctly by using a 120-ohm 0.25W resistor at each END of the bus system.
- Maximum Stub length to a device from the main Bus is recommended at 0.3m, in accordance with High-Speed ISO 11898 Standard specification. See Figure 3.3.
The ELC devices do not include an on-board CAN termination resistor, allowing the device to be wired at any position on the Bus. CAN Bus termination must be done correctly by using a 120 ohm 0.25W resistor at each end of the bus system as mentioned above. Figures 3.1 and 3.2 show possible CAN Bus Implementation examples
ELC CAN Bus
The ELC devices can be connected to the ECUs CAN Bus 1 or 2.
All devices on the CAN Bus must be configured to use the same baud rate. For
this reason, all Emtron CAN devices will Auto-scan the CAN bus until a
successful baud rate has been detected. Once detected this rate will be stored
and used at the next power up. The device will scan 3 different Baud rates at
500ms intervals moving from 1Mbaud -> 500kBaud -> 250k Baud -> 1Mbaud and so
on.
NOTE : For this process to function effectively when new devices are
introduced to the CAN bus, they should initially be connected one at a time.
This allows each device to sync up to the CAN Bus baud rate and store that
setting. This typically takes 3-5 seconds.
The ELC devices leave the factory programmed with individual serial numbers,
but all have the same Base CAN-Address ID used to transmit data over the Bus.
The CAN Base address can be adjusted from the factory setting using the ID
Reprogramming Tool. This is required when 2 or more of the same devices are
connected to the CAN Bus (See section 4.2).
- Factory CAN Base Address of 671. Transmits data sequentially on the next ID. Total CAN ID Range is therefore 671 – 672.
- Up to 6x ELC devices (ELC or ELCM) can be used on the CAN Bus giving a total of 12 available Lambda Channels.
Noise Immunity
To minimize signal contamination and maximize noise immunity, the wire pairs
shown in Table 3.2 must be twisted. It is recommended to twist the wire pairs
at a minimum one twist per 40mm of cable. This is very important and should
always be implemented on both CAN Bus and LSU Sensor wiring.
Pair 1 | Pair 2 | |
---|---|---|
CAN High | <——-> | CAN Low |
Pump Current | <——-> | Cal Resistor |
Nernst Cell Voltage | <——-> | Virtual Ground |
Table 3.4. Wire pairing for twisting
Lambda Sensor Installation
Installation angle must be inclined at least 10° towards horizontal,
(electrical connection upwards) up to a maximum of 75°. This prevents the
collection of liquids between sensor housing and sensor element during the
cold start phase.
The angle against the exhaust gas stream should be aimed as 90°. Maximum
inclination should be 90°+15° (protection tube towards gas stream) or 90°-30°.
NOTE : NEVER mount the sensor directly on the horizontal or within 10
degrees of the horizontal. Doing so will result in intermittent sensor
shutdown.
- Also, route the sensor cable to avoid high moisture locations – just a small amount of moisture is enough to provide a conductive path within the connector that will upset measurement from the sensor.
- Winter and salted roads compound this issue. Always check for a cracked or broken connector when strange results occur.
Heater Control and Sensor Calibration
Heater Control
During engine start-up, condensation forms in the exhaust which may damage the
sensor. It is recommended to only start heating the LSU sensor after the
engine is running and the moisture content in the exhaust has evaporated. ELC
settings allow the ECU to control heater setup if enabled.
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.
Once changed, the settings are automatically stored by the ELC and therefore used on the next power cycle. If the CAN bus is not used to control the heater (Enable Heater Override = OFF), then by default the heater remains OFF for 15 seconds after the device is powered up.
Sensor Calibration
The sensor is calibrated by the ELC on power-up. During the Calibration
process, two important pieces of data are read:
- The optimal Nernst Cell Temperature is used for sensor heater control. The ELC applies a duty cycle and a PID routine to maintain a constant and accurate heater temperature which results in a very stable and accurate Lambda value.
- The Pump Current corresponds to a Lambda reading of 1.000 Lambda.
NOTE : Free-Air Calibration is NOT required on the LSU4.9. The sensor uses a reference pump current instead of reference air. The big advantage of this is that the reference is a calibrated electrical signal and remains constant.
Exhaust Back Pressure (EMAP) Compensation
- Wideband Lambda sensors primarily count oxygen atom numbers by measuring the oxygen ion current within the sensor’s pump cell. The exhaust gas pressure affects this oxygen ion current. More pressure means more atoms per unit volume and a higher pump current at the same Lambda i.e. this will cause the sensor to read farther from stoichiometric.
- A rich reading will appear richer than it really is.
- A lean reading will appear leaner than it really is.
- This predominantly becomes an issue in Turbocharged applications. This is the main reason you should position the sensor after the turbo where exhaust back-pressure is lowest.
- Excessive Exhaust Back Pressure (EMAP) can also damage the sensor. The following rule should be observed:
Exhaust Back Pressure < 2.5 Bar
When measuring Exhaust Back Pressure, an Absolute Pressure Sensor MUST be
used. (i.e. do not use a Gauge Pressure Sensor). The ECU MUST have the Exhaust
Manifold Pressure channel configured so data transmitted from ECU to ELC is
valid.
The EMAP setting can be enabled by going to 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 receive this
value so the correction can be applied. NOTE : Once changed, the setting
is automatically stored by the ELC and therefore used on the next power cycle.
ELC Device Configuration
Once the ELC is powered and connected to the ECU’s CAN bus, the following steps should be taken to complete the setup. All setup and device monitoring is done using Emtune so this software needs to be installed and connected to the ECU.
ELC Single Device Setup
This section outlines the setup procedure for a single device and involves 2
steps:
- Device Detection by the ECU
- ECU CAN Bus configuration
ELC Device Detection
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:
- CAN Device Model
- Device Serial Number
- Device Firmware Version
- Device Hardware Version
- CAN Base Address ID
With a single ELC device connected, the data should look as shown in Figure 7.0/7.1.
Important:
- At this stage the ECU has only detected the device. It has not been configured to an ECU CAN Channel so the ELC data is not yet available.
- Note the CAN Base Address ID. This is required in the ECU CAN setup. The factory setting is ID 671 for the ELC and ELC2M.
ECU CAN Channel Configuration for Single Device
The next step is to configure an ECU CAN channel, allowing the ECU to decode
the ELC CAN packets.
For this example, CAN 1- Channel 1 has been selected.
- Set “Enable” to (ON)
- Set “CAN Base Address” to the ID shown in Figure 7.0/7.1 In this example its ID 671.
- Set “DATA Set” to 50 (ELC/ELC2M 1x Device). See Figure 7.2.
The ECU in now configured and reading the data from the ELC Device.
ELC Multiple Device Setup
As mentioned in section 3.5, the Base CAN-Address ID used to transmit Data
over the Bus by default is the same for each device type. The ELC has a
factory CAN Base Address of 671. When multiple ELC devices are installed on
the same CAN Bus, each device MUST have a unique CAN Base Address to avoid Bus
conflicts. This means the CAN Base Address ID will need to be reprogrammed
which is a simple task using the ID Reprogramming Tool as outlined in section
7.22.
REMEMBER : For this process to function effectively when multiple new devices are introduced to the CAN bus, they should initially be connected one at a time. This allows each device to sync up to the CAN Bus baud rate and store that setting. This usually takes 3-5 seconds.
ELC Multiple Device Detection
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:
- CAN Device Model
- Device Serial Number
- Device Firmware Version
- Device Hardware Version
- CAN Base Address
With multiple ELC devices connected, the CAN Summary List should look as shown in Figure 7.3. In this example x2 ELC2 devices are connected to the BUS. Device 1 with SN 1241 and Device 2 with SN 1242.
Note : ALL devices have the same Base Address of ID 671, which is the factory setting for a single device. To avoid Bus conflicts, the factory base address needs to be changed when multiple devices are used, to ensure each device has its own unique ID. When re-programming the Base Address for each device the IDs MUST be:
- Sequential in order.
- Have a gap of 2 numbers between each ELC device.
The Base Address ID can be any number but Emtron recommends the following:
- ELC Device 1: ID Base Address 671. (CAN ID Range 671-672)
- ELC Device 2: ID Base Address 722. (CAN ID Range 673-674)
- ELC Device 3: ID Base Address 722. (CAN ID Range 675-676)
- ELC Device 4: ID Base Address 722. (CAN ID Range 677-678)
- ELC Device 5: ID Base Address 722. (CAN ID Range 679-680)
- ELC Device 6: ID Base Address 722. (CAN ID Range 681-682)
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. This is easily done using Emtune from the Config view ->
Communications Menu -> Emtron CAN Devices -> Emtron CAN Device Programming
menu. In this example select:
Device 2 ID Reprogramming
- Enter in Serial Number = 1242 Enter in Custom Address = 673
- Make sure the “Program Address” checkbox is ticked.
Select the “Program” button and the new Custom Address ID will be programmed
into the device.
To check the device has been correctly programmed with the new CAN Base
Address, open the F3 menu -> Communications Tab. CAN device 2 with SN 1242
should have a new Base Address of 673. See Figure 7.5
ECU CAN Configuration for Multiple Devices
The next step is to configure an ECU CAN channel, allowing the ECU to decode
the ELC CAN packets.
Only 1 CAN Channel is required for multiple devices. CAN 1 – Channel 4 has
been selected. Config as follows:
- Set “Enable” to 1(ON)”
- Set “CAN Base Address” to the Lowest Base Address ID shown in Figure 7.5. In this example its 671.
- Set “DATA Set” to 51 -Emtron ELC/ELCM 2x Devices (CAN PID 671/673).
The ECU is now configured and will receive data from all devices on IDs
671-672, 673-674.
NOTE : You only need to program in the lowest Base Address . The ECU
automatically configures the remaining IDs based on the assumption that the
IDs are sequential in order.
ECU Channel Configuration
Once the ECU has been configured to receive the ELC data, the next step is
assigning the data to an ECU lambda channel(s). There are several options:
Option A : Use the Lambda 1 and Lambda 2 Input Channel(s) as shown in
Figure 8.0. With a ELC1 set the Lambda 1 to CAN ELC #1 Ch-A and for an ELC2
set Lambda 1 to CAN ELC #1 Ch-A and Lambda 2 to CAN ELC #1 Ch-B.
When this option is used the Runtime menu (F3) -> Lambda tab can be used to view the data from both channels. This includes Lambda data and Diagnostics data to help with fault finding should any issues occur. See Figure 8.1.
Options B: Use the Lambda Cylinder Input Channels. This setup is normally done when multiple ELC devices are used to measure the lambda on individual cylinders. Figure 8.2 shows four ELC devices configured, measuring the individual Lambda on an 8-cylinder engine. Example setup:
- To configure the ELC Device 1:
- Channel A to Cylinder 1; set the Channel Input Source for Lambda Cyl 1 to CAN ELC #1 Ch-A
- Channel B to Cylinder 2; set the Channel Input Source for Lambda Cyl 2 to CAN ELC #1 Ch-B
- To configure the ELC Device 2:
- Channel A to Cylinder 3; set the Channel Input Source for Lambda Cyl 3 to CAN ELC #2 Ch-A
- Channel B to Cylinder 4; set the Channel Input Source for Lambda Cyl 4 to CAN ELC #2 Ch-B
… etc for ELC Device 3 and 4
ELC Custom Device Settings
The following settings are available to control the ELC. These settings get applied to ALL ELC devices connected on the CAN bus.
- Reset CAN IDs to Default
- Enable Heater Override (See Section 5.0)
- Enable EMAP (See Section 6.0)
- ELC Heater RPM Lockout (See Section 5.0)
- ELC Heater Post Start Lockout (See Section 5.0)
- ELC Lambda 1 Test Enable
- ELC Lambda 2 Test Enable
These settings are available from the Config View -> Communications Tab -> Emtron CAN Device -> Emtron Lambda to CAN (ELC/ELCM) Setup”. See Figure 9.0
The ELC Lambda 1 and 2 Test Enable setting will force the ELC device to send
the Test Lambda value over the CAN bus. The ECU will read that value and it’s
a simple way of confirming the system is calibrated correctly. Make sure this
setting is reset back to zero when finished.
NOTE : When any custom ELC setting is changed, the setting is
automatically stored by the ELC device and therefore used on the next power
cycle.

Appendices
Appendix 1 – CAN Bus Data Packaging
This section outlines the CAN Protocol used to communicate with the ELC
device(s). If the device is connected to an Emtron ECU, the CAN Bus packet is
automatically decoded when CAN ELC Dataset is selected and no additional setup
is required. For more information refer to Section 7.0.
This section provides more detailed information on the CAN ID data structure
and requires an understanding of both CAN protocols and data packaging.
Baud Rate
The device will Auto-scan the CAN bus until a successful baud rate has been
detected. Once detected this rate will be stored by the device and used at the
next power up.
The device will scan 3 different Baud rates at 500ms intervals moving from
1Mbaud -> 500kBaud -> 250k Baud -> 1Mbaud and so on.
