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

The DB-Gauge Kit Blue w/ LC-2 & O2 Sensor from Innovate Motorsports is a precision engine monitoring system designed for high-performance vehicles and professional motorsports applications. This kit brings real-time combustion data to operators who demand accuracy in fuel mapping, tuning, and engine diagnostics—critical for both competitive racing environments and advanced automotive work. Whether you're fine-tuning a modified engine or troubleshooting fuel delivery issues, this comprehensive gauge package delivers the instrumentation serious enthusiasts and technicians rely on.

This kit integrates dual wideband technology with the included LC-2 lambda controller and O2 sensor, allowing precise air-fuel ratio (AFR) monitoring across a wide operating range. The blue-faced gauge provides clear, legible readings even under high-intensity lighting conditions common in shop and track environments. The O2 sensor directly measures combustion efficiency, enabling data-driven adjustments to fuel curves and ignition timing; the LC-2 controller processes sensor input and communicates real-time values to the digital display with minimal lag. Compact dimensions (7.4 x 2.9 x 10.9 inches) and lightweight construction (1.95 lbs) make installation straightforward in tight engine bays without compromising durability or signal integrity.

Professional engine tuners, dyno operators, and motorsports competitors benefit most from this kit's precise AFR feedback, which informs critical tune decisions that directly impact horsepower, reliability, and fuel economy. Installation requires routing the O2 sensor into the exhaust stream—ideally in the header or primary collector—and mounting the gauge and controller in accessible dashboard positions. This system pairs seamlessly with piggyback ECUs, standalone engine management systems, and manual tuning platforms, making it an essential tool for anyone serious about extracting maximum performance and data integrity from modified powerplants.
