DB-Gauge Kit Red w/ LC-2 & O2 Sensor

The DB-Gauge Kit Red w/ LC-2 & O2 Sensor by Innovate Motorsports is the go-to air-fuel ratio monitoring system for serious engine builders, tuners, and performance enthusiasts who demand real-time combustion data. Whether you're dialing in a carbureted engine, fine-tuning a fuel-injected platform, or validating tune work on a dyno, this gauge kit provides the feedback necessary to optimize power delivery while protecting against lean-out conditions that destroy pistons and rings. The red faceplate design complements aggressive engine bays while maintaining professional legibility under all lighting conditions.

At the heart of this system is the LC-2 controller paired with a precision O2 sensor—Innovate's proven combination for accurate air-fuel ratio measurement across the full operating range from 10:1 to 20:1 lambda. The LC-2 module processes sensor input and drives the analog gauge needle with repeatability that eliminates guesswork during tuning sessions. Your included O2 sensor is calibrated to work seamlessly with the controller, ensuring consistent readings whether you're logging street cruising or peak power pulls; the gauge housing measures 7.4 x 2.9 x 10.9 inches, fitting standard 2-inch or 2.375-inch pillar mounts or dash pods. The 2-pound kit is compact enough for engine swaps and confined engine bays without sacrificing visibility or accuracy.

This kit excels for naturally aspirated, turbocharged, and supercharged builds running any fuel type—gasoline, E85, or methanol—because the LC-2 compensates for fuel type variations automatically. Mechanics and tuners rely on this system during cold-start calibration, idle quality optimization, and wide-open-throttle validation to confirm that fuel mapping matches actual combustion events. Installation requires basic wiring skills and O2 sensor bung access in your exhaust manifold or header; once mounted, the gauge becomes an indispensable diagnostic tool for catching lean conditions, verifying injector trim accuracy, and documenting tune stability before and after modifications.
