GEN4 PRO XTREME – BOSCH LSU4.9 WBO2 Sensor

The Bosch LSU4.9 wide band air fuel ratio sensor is our standard air fuel ratio sensor when using the GEN4 ECU. This robust sensor can be used for any fuel combination including gasoline, ethanol and alcohol. Within the GEN4 software you simply tell it what type of fuel your running and the stochiometric value for the fuel being used and the ECU takes it from there. 

The GEN4 system can run anywhere from 1 oxygen sensor to a dual sensor setup for reading dual exhaust or for the ultimate in inputs and control, 8 air fuel ratio sensors. The GEN4 ECU can run closed loop control using any of the previous combinations including the 8 sensor configuration. With the power to individual monitor and control each cylinder you will be able to unleash more power and torque from your current combination!

We do not recommend this sensor for high power alcohol setups but in mild combinations it will work fine.
