LM-2 Air/Fuel Ratio Meter Dual O2 Basic Kit

The LM-2 Air/Fuel Ratio Meter Dual O2 Basic Kit from Innovate Motorsports is a professional-grade wideband oxygen sensor monitoring system designed for engine tuning, diagnostics, and performance optimization. This dual-sensor configuration allows simultaneous monitoring of air-fuel ratio across multiple cylinders or exhaust banks, making it essential for serious enthusiasts, tuners, and shops seeking precision feedback during dyno testing, street tuning, or competition preparation. The digital display provides real-time AFR data that directly influences fuel mapping decisions and engine efficiency.

This wideband system operates using dual O2 sensors that detect exhaust oxygen content across a wide range of air-fuel ratios—from lean (high oxygen) to rich (low oxygen)—delivering accuracy far superior to narrowband sensors. The electric digital display reads AFR values in real time, allowing tuners to adjust fuel delivery and ignition timing with immediate feedback. The basic kit includes O2 sensors, connecting cables, a power adapter for vehicle electrical integration, and mounting hardware, enabling straightforward installation on most performance vehicles. The black-faced digital gauge provides clear visibility in various lighting conditions and mounts securely in standard dash or pillar positions.

Street racers, engine builders, and serious DIY tuners rely on the LM-2 to validate fuel curve accuracy and prevent lean-condition damage during high-rpm operation. Installation is compatible with carbureted, naturally aspirated, turbocharged, and supercharged engines—wherever dual exhaust streams or cylinder banks benefit from independent AFR monitoring. The compact 7.2 x 2.5 x 10.8-inch display unit fits tight engine bays and interior spaces, while the included sensors and cables accommodate most exhaust manifold configurations. Whether tuning a street car, drag vehicle, or performance build, this dual O2 basic kit delivers the critical data needed for safe, efficient engine operation.
