Innovate DB-Gauge AFR Display Gauge – Blue LED | 52mm | Gauge Only | INN3793

The Innovate DB-Gauge is a 52mm (2-1/16”) air/fuel ratio display gauge with a bright blue LED display — designed to connect to and display the AFR output from an Innovate Motorsports wideband lambda controller. A cost-effective, clean-looking dash display solution for tuners who already own an Innovate LC-1, LC-2, LM-1, or LM-2 controller and want a dedicated, permanently mounted AFR readout in the cabin. Universal fit — standard 52mm gauge pod or dash hole.

Gauge Only — What That Means

The DB-Gauge is a display only — it does not contain a wideband oxygen sensor controller, does not process the O2 sensor signal, and cannot function independently. It reads the analogue or serial AFR output signal from a compatible Innovate wideband controller and displays it on the LED gauge face. To use the DB-Gauge you need:

• A compatible Innovate wideband controller already installed in the vehicle: LC-1, LC-2, LM-1, or LM-2
• The appropriate Innovate serial or analogue cable to connect the controller output to the DB-Gauge input

If you do not already have an Innovate wideband controller, a complete Innovate wideband kit (controller + sensor + gauge) is the correct starting point.

Key Features

• 52mm (2-1/16”) Diameter: Standard gauge pod size — fits any 52mm gauge pod or dash panel cutout. The most common aftermarket gauge diameter
• Blue LED Display: Bright LED face with blue illumination — this listing is the blue variant. Also available in green and red (separate listings)
• AFR Display: Displays air/fuel ratio received from the connected Innovate controller in real time — provides a clean, dedicated dash-mounted AFR readout separate from a laptop or handheld display
• Compatible Controllers: LC-1, LC-2, LM-1, LM-2 — connects via Innovate’s serial cable output from the controller
• Cost-Effective Display Upgrade: For tuners already running an Innovate controller on a laptop or who want to add a dedicated dash gauge without purchasing a full second wideband kit — the DB-Gauge adds a permanent in-cabin AFR display for the existing controller

Gauge display only — does not include wideband controller, O2 sensor, or bung. Requires compatible Innovate wideband controller (LC-1, LC-2, LM-1, or LM-2) and appropriate Innovate serial cable (sold separately). Confirm cable compatibility with your specific controller model before ordering. Universal 52mm fitment — gauge pod or panel not included.
