The Haltech Wideband Controller is a plug and play wideband solution for your Haltech system. It allows users to accurately measure air-fuel ratios over a wide range and deliver that information via CAN to a Haltech or supported third-party ECU.
This product enhances the functionality of all Haltech Nexus, Elite, and Platinum ECUs with its plug-and-play CAN compatibility. It is easily programmed and controlled through NSP, ESP, or ECU Manager software. There are two versions of the WB1 and WB2 controllers: one designed to control Bosch LSU 4.9 sensors and the other to control NTK LZA08-H5 sensors.
