Description:
The Bosch LSU 4.2 Wideband O2 sensor is a crucial component for monitoring and optimizing engine performance, delivering accurate measurements of your engine's air-fuel ratio in real-time, determining the lambda value.
The Bosch LSU 4.2 WB-O2 sensor is compatible with unleaded gasoline, ethanol gasoline blends, methanol, and diesel. However, the sensor's lifespan is significantly reduced when used with leaded fuel, diesel, or in 2-stroke engines.
Thread Size:
The Bosch LSU 4.2 sensor has a thread size of M18 x 1.51.
Installation and Calibration:
To operate the sensor effectively, youll need to pair it with a wideband O2 signal conditioner (also referred to as a wideband O2 controller). When paired with a FuelTech wideband O2 controller, the sensor is automatically calibrated.
The Bosch part number for this sensor is 0 258 007 057 (VW Number: 021-906-262-B)2.
Additional Information:
If youre looking for a compact solution, consider the WB-O2 Nano. It features an extended reading scale down to 0.35 ? and offers CAN communication with FuelTechs Power FT line ECUs. This is especially useful when using an O2 sensor per cylinder.
For the most versatile solution, the NanoPRO is compatible with 5 different wideband O2 sensors (Bosch 4.2, 4.9, 5.2 and NTK Wideband O2, NTK ZFAS), configurable heating modes, extended reading scale (reading range can reach values slightly lower than 0.21 ?), customizable dash display with 2" color touchscreen, virtual switch panel, and CAN communication with all FuelTech ECUs. The NanoPRO is IP67 rated when properly connected to the harness.
Remember to handle the sensor with care and never remove the O2 sensor connector during operation. If you have any specific applications or questions, feel free to explore further!
