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 ECU.

This product enhances the functionality of all Haltech Nexus and Elite ECUs with its plug-and-play CAN compatibility. It is easily programmed and controlled through the NSP 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 / LZA09-E1 sensors.

This Kit is supplied with 1 x NTK LZA09-E1 Laboratory Grade Sensor (6mA)
