Digital Wideband Controller
Digital Bosch LSU 4.9 wideband controller that streams Lambda/AFR over CAN straight to your Link G4+/G4X ECU — no analogue signal loss.

CANDigital Lambda output
0.67–10 λLambda sensing range
G4+/G4XLink ECU compatible
Overview
The Link CAN-Lambda (product code CANLAM, part 125-1000) is a digital wideband air/fuel controller. It uses a digital Bosch lambda controller to run, monitor and diagnose a Bosch LSU 4.9 wideband oxygen sensor, then broadcasts Lambda and sensor data over the CAN bus to your ECU — eliminating the signal loss, delays and errors of analogue widebands. It never requires free-air calibration.
Made for anyone tuning a Link G4+/G4X (or other CAN-capable aftermarket ECU) who wants accurate, fully digital wideband feedback for closed-loop fuel control and data logging, with no gauge or analogue output wiring to install.

Fitment
ApplicationLink G4+/G4X ECUs via CAN; also most other CAN-capable aftermarket ECUs
InstallWeld the supplied bung into the exhaust, fit the LSU 4.9 sensor, and wire the 4-pin DTM to your ECU's CAN bus, then set it up in the tuning software. On G4+/G4X PlugIn ECUs this needs a Link CANPCB cable and CANF plug (sold separately).
Confirm your ECU has a spare CAN bus port and the correct Link CAN cable/plug for your model before ordering.
Best suited for
Closed-loop tuning
Wideband AFR logging
Link G4+/G4X builds
A CAN cable to the ECU is not included — G4+/G4X PlugIn ECUs need a separate Link CANPCB cable and CANF plug. The Bosch LSU 4.9 sensor carries no manufacturer warranty in aftermarket use.
