4.2 Four WB-O2 Nano harness

EN
This harness was developed to power up to
four WB-O2 Nano readers and four wideband
O2 sensors, for builds needing individual fuel
reading per cylinder.
Electrical connections and wire colours are the
same as a regular WB-O2 Nano.
5. Bosch LSU 4.2 Wideband
O2 Sensor
Bosch LSU 4.2 sensor has an encased heating
element and it is used to measure the air fuel
ratio, which determines the lambda value in the
remaining exhaust gas. Its signal indications
vary from 5.14AFR Gas (0,35λ)lambda (rich
mixture) to open air lambda (infinite).
The connector includes a calibration resistor
(factory calibrated), which defines the
characteristics of the sensor and it is necessary
for its operation. It is with this resistor that the
WB-O2 Nano automatically calibrates the
sensor.
Bosch LSU Oxygen Sensors are not developed
6
to operate with fuel containing lead, and its life
cycle is drastically reduced to an estimated 50
to 500 hours if used in such conditions.
Whenever the sensor is installed in the exhaust
and the engine is running, the sensor MUST
be connected to FuelTech WB-O2 Nano,
which also needs to be in operation. That is
to prevent the equipment from being rapidly
damaged from exposure to the exhaust gas
without heating control.
