4 – Powering LCU-One CAN controller
The wideband Lambda probe has a working temperature of about 780°C (1436°F); for this reason it is constantly monitored by the Lambda
controller LCU-One CAN, that tunes the power supplied by an external 12V battery.
The warm-up can drain up to 1.6A while the average consumption is approximately 1A, thus if the vehicle doesn’t have an alternator, it is
recommended to install a battery that can last several hours feeding the whole logging system. A 4 cells LiPo battery with a capacity of
3000mAh, for example, can guarantee 3 hours of activity.
LCU-One CAN controller has to be connected directly to the external 12V battery, using the three leads (one red and two black) supplied
with spade connectors. They all have to be correctly connected with no dispersions, bad crimping, oxide or thin section wires causing an
inadequate current supply to warm-up the Lambda probe. These are the most common causes of bad reading and premature poisoning
of Lambda probes.
The addition of a protection fuse (i.e 5A) is suggested, and if a switch is added, make sure it can comply with the electrical current rates
indicated above.
