Link Can Lambda

Link CAN Lambda Digital Wideband Controller

Stop guessing at your air-fuel ratio. The Link CAN Lambda delivers fully digital wideband oxygen sensor data straight over CAN bus, giving your ECU the clean, real-time input it needs to fine-tune fuel mixtures on the fly.

Why Tuners Choose the Link CAN Lambda

• Fully digital, zero compromise: By communicating over CAN bus instead of an analogue signal, the CAN Lambda eliminates the signal loss, noise, delays, and wiring errors that plague traditional wideband controllers.
• Bosch LSU 4.9 sensor: A proven, industry-standard wideband sensor delivers accurate exhaust gas oxygen readings across a broad 0.67–10 lambda sensing range.
• No free-air calibration required: Install it and get on with tuning. The CAN Lambda is built to perform reliably without the recalibration hassle of older wideband setups.
• Seamless ECU integration: Designed to work with leading aftermarket ECUs, including Link G4+ Plug-In ECUs. For a G4+ Plug-In install, simply add a Link CANPCB cable to access the CAN port on the PlugIn PCB along with a Link CANF field-insertable CAN plug. Proper CAN protocol must be followed; see the manual for guidance.
• Flexible CAN speeds: Supports 1 Mb/s, 500 kb/s, 250 kb/s, and 125 kb/s CAN frequencies for straightforward integration into your existing bus setup.
• Compact and easy to mount: A small 60 x 26 x 15 mm enclosure with a 170 mm lead and a weight of just 70 g means it tucks into an engine bay or interior without a fight.
• Built for real-world use: Operating temperature range of -20°C to 100°C, controller input voltage of 7.5–20 V, and sensor input voltage of 10.8–16.5 V make it suitable for street and motorsport applications across Canadian conditions.
• Complete, ready-to-install kit: Every box includes the CAN-Lambda device, Bosch LSU 4.9 sensor, Deutsch 4-way connector kit, O2 bung and plug, two large stickers, two small stickers, and a Quick Start Guide.
