Link’s CAN Lambda is an easy to use CAN module that provides digital wideband sensor control via CAN bus and is compatible with leading aftermarket ECUs. This bundle contains TWO CAN Lambda kits. If using the CAN Lambda with a G4+/G4X PlugIn ECU use a Link CANPCB cable to access the CAN port on the PlugIn PCB and a Link CANF field insertable CAN plug. Please note the LSU4.9 sensor in this unit is sold solely for aftermarket use. As Bosch’s warranty excludes aftermarket applications, no warranty is provided on the LSU 4.9 Sensor. We have prepared some information about how to increase sensor lifespan here. Please note proper CAN protocol must be followed. See manual below for guidance.
