WB2 Bosch Dual Channel O2 Controller Kit

The WB2 Bosch Dual Channel O2 Controller Kit from Haltech is designed for tuners and performance engine builders who require precise fuel mixture control across various load conditions. This kit is suitable for carbureted engines, forced-induction setups, and heavily modified naturally aspirated platforms, enabling optimized combustion efficiency and enhanced power output.

The dual-channel controller processes input from two independent Bosch wideband oxygen sensors, allowing for separate or simultaneous control over front and rear cylinder banks. It interprets raw sensor data and outputs corrected voltage signals that your engine management system reads as fuel trim commands, enabling you to target specific air-fuel ratios without needing to reflash your ECU.

This kit is ideal for street performance builds, vintage restoration projects, and competition vehicles where precise air-fuel ratios are crucial for achieving consistent results. The compact form factor and low weight facilitate straightforward installation in tight engine bays, ensuring that performance enthusiasts can easily integrate it into their setups.
