7.1 Emtron Lambda to CAN
The ELC uses Bosch proven integrated circuit technology to precisely control an LSU4.9
Lambda sensor. The Lambda value is transmitted over the CAN Bus and can be used by the
ECU for Tuning and Closed Loop control. More information is available by looking at the
Emtron ELC User Manual.
The ELC Power, Ground and CAN wires can be directly connected into the IO Expansion
Loom as outlined in Table 7.0.
