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, the engine richness (or Lambda, A/F or O2) can be directly visualized.

LSU49-5 LAMBDA-METER KITS

• The Lambda control module is provided with accessories to install it on the engine.

• LSU49-5 can be directly used with Sybele ECUs.

• For a direct display of the richness measurement, the DC4D52 display must be added to the LSU49-5 controller.

Lambda sensor Bosch LSU 4.9

 

 

 

 

*LOOM 
• On Lambda sensor connection side, the loom is completely sheathed with braid sleeving and the sensor connector. The length to the sensor loom is 0.60 m.
• On ECU side, the loom (ground, power supply, analog output) is made of wires without connector. The loom length is 0.30 m.
