2. Installation of the KMS UEGO CAN controller
The KMS UEGO CAN controller is splash waterproof. However, it is best to
place it in a dry place where temperatures don’t exceed 65 °C.
Warning: do not place the UEGO CAN controller and it’s wires nearby any
‘high powered’ cables such as sparkplug leads, as it can cause electrical
interference resulting in malfunction.
Included with the KMS UEGO CAN controller is a wiring loom which consists
Lambda connector ECU connection CAN-bus
Main connector Ground connector

3. Wiring of the CAN bus
The KMS UEGO CAN controller can communicate via CAN communication through
the CAN bus (grey wire) which consists of two pair of twisted wires (green and
white, red and black). Up to 10 CAN devices may be connected to the CAN bus.
These devices must be placed within 0,5m of the CAN bus.
If the CAN Bus is connected to the KMS MP25, MA25(M), IA23 or FA23 ECU (using the
serial to CAN converter) or the KMS MD35 ECU, it is not necessary to use a CAN ter-
minating resistor plug. The KMS MD35 ECU and serial to CAN converter already have
a terminating resistor. When using the UEGO CAN controller separately on a
standalone CAN bus (for example in combination with a KMS CAN display), it is nec-
essary to use a CAN terminating resistor plug on one end of the CAN bus. Below, a
drawing is shown of the correct CAN Bus wiring, including a KMS ECU. The following
page contains a drawing showing the correct wiring of the CAN bus excluding a KMS
ECU.

4. Lambda sensor specifications
The lambda sensor used for the KMS UEGO CAN controller is a 6 wire LSU4.9 wide-
band Lambda sensor. This sensor has the following specifications:
• Thread: M18x1,5
• Spanner size: 22 Hexagon
• Maximum continuous operating temperature: 930 °C
• Maximum temperature: 1030 °C (maximum 10 minutes)
• Mounting torque: 60 Nm max
• Sensor warm-up will take about 20 seconds. Accurate measure-
ment is possible when exhaust gas temperature is at working
temperature.
• Sensor lifetimes differ for every application, but will dramatically
decrease by the following factors:
• Leaded fuel
• Contaminants such as silicon, lead, oil, etc. (use sensor
-friendly sealants)
• Exposure to exhaust fumes without any heating control active
• Incorrect placement in the exhaust that can overheat
the sensor (for correct placement see page 5)

Warning: The Lambda sensors are factory calibrated with a trim-
ming resistor placed in the sensor connector, so the connector must
not be cut off.
5. Installation of the lambda sensor
The Lambda sensor should be fitted to the exhaust system with the sensor
tip in the exhaust gas flow. When fitting the Lambda sensor, the following
factors need to be taken into account:
• Place the sensor at least 1 meter fron the open end of the exhaust
system to avoid incorrect readings due to air from the outside.
• If possible, do not place the sensor near exhaust slip joints. It is pos-
sible for some applications to allow air to enter resulting in incorrect
readings.
• Installation angle should be inclined at least 10° towards horizontal
(electrical connection upwards). Thus preventing the collection of
liquids between sensor housing and sensor element during the cold
start phase. See figure below.
