LSU ADV Wideband O2 Sensor

OUT OF STOCK UNTIL FURTHER NOTICE       100% Bosch made LSU ADV Wideband Wideband O2 Sensor. Compatible with Spartan 3 ADV. 3-month warranty     The Bosch LSU ADV is arguably the successor to the popular Bosch LSU 4.9 and brings many minor upgrades such as; ~15% increase in Lambda accuracy, slightly higher maximum temperature tolerance, more optimized vents for better exhaust flow into and out of the sensor, smaller heater and lower thermal mass. The biggest upgrade that the ADV sensor brings is that it does not require a calibration resistor for ~0.01 Lambda accuracy because the sensor is made precisely. The 4.9 is made less precisely than the ADV and each sensor is then tested and a bespoke lazer cut resistor is installed into the sensor connector that compensates for the imprecision of the manufacturing process, this allows the LSU 4.9 to achieve 0.01 Lambda accuracy. A wideband controller measures very small currents into and out of the sensor pump cell to determine Lambda, typica
