Ecumaster Lambda to CAN The Ecumaster Lambda to CAN is a high-performance, compact wideband controller designed to provide industry-leading accuracy in air-fuel ratio (AFR) monitoring. By utilising a dedicated Bosch integrated circuit paired with an automotive-grade digital controller, this module precisely manages a Bosch LSU 4.9 wideband oxygen sensor. It converts complex sensor data into a high-speed digital stream transmitted via CAN BUS, ensuring your ECU receives the most accurate fuelling data possible without the signal degradation associated with traditional analogue wiring. Housed in a rugged, IP67-rated enclosure, this module is engineered to thrive in the harsh environments of a motorsport engine bay. It is an essential component for high-end tuning, enabling closed-loop Lambda control and individual cylinder trimming when integrated with Ecumaster EMU Black, EMU PRO, or ADU display units. Technical Authority & Key Features Advanced Bosch LSU 4.9 Support: Specifically calibrated for the LSU 4.9 sensor, providing a measurement range from 0.5 to 8.0 Lambda. High-Speed CAN 2.0A/B Communication: Transmits data at user-selectable bitrates (up to 1Mbps), allowing for seamless integration into any professional CAN network. Dual Programmable Analog Outputs: Features two 0-5V analog signal lines, making it compatible with older ECUs or data loggers that do not support CAN BUS. Multi-Controller Flexibility: Multiple Lambda to CAN modules can be used on a single bus, facilitating easy dual-bank or per-cylinder monitoring for V6, V8, and V12 engines. Intelligent Heater Control: Precise PWM management of the sensor heater prevents thermal shock and extends the lifespan of the Bosch sensor. Light Client Configuration: Fully adjustable via the Ecumaster Light Client software, allowing for easy updates and diagnostic monitoring through a USB to CAN interface. Rugged Construction: Compact dimensions (104mm x 25.5mm x 25mm) and an IP67 waterproof rating (when connected) ensure reliable performance in rally, circuit, and marine applications.
