This Lambda-meter (wide band Lambda sensor control module) uses LSU4.9 Bosch Lambda sensors to measure the engines richness. It can measure richness on gazoline engines and diesel engines as well.

Unlike other kits on the market that use a sensor LSU 4.2, it never needs to be calibrated and provides a very performing and stable richness measurement.

This Lambda-meter delivers its richness measurement with an analog output.

It is specifically adapted to work with the Sybele engine management ECUs (Commander, Challenger4, …) but can work with other ECU brands as well, or directly with a data recording system or a digital dash board.

By adding its specific display DC4D52, the engine richness (or Lambda, A/F or O2) can be directly visualized.
