The Haltech WB2 Dual Channel CAN Wideband Controller provides simultaneous monitoring of two independent oxygen sensors through a single compact unit. Designed for professional tuning environments, this controller communicates directly via CAN bus, eliminating analogue signal interference and simplifying harness integration. Each channel supports accurate air-fuel ratio measurement across the full operating range, essential for optimising fuel maps and confirming combustion efficiency. The WB2's dual-channel architecture suits complex setups requiring pre and post-cat monitoring, or independent bank measurement on V-configuration engines. Compatible with Haltech ECU platforms for seamless data logging and real-time display integration.
