LM-2 Single Wideband O2 Sensor Kit

The LM-2 Single Wideband O2 Sensor Kit from Innovate Motorsports is the cornerstone tool for any serious engine tuner or performance mechanic looking to dial in precise air-fuel ratio management. Whether you're running a naturally aspirated street engine, a turbocharged build, or a dedicated track car, this wideband oxygen sensor kit provides real-time combustion data that's essential for safe and efficient tuning. Unlike narrow-band factory O2 sensors that only signal rich or lean conditions, the LM-2 delivers continuous, accurate AFR readings across the entire operating range—critical information for optimizing fuel maps, verifying carburetor jetting, or validating ECU calibrations.

The LM-2 kit features a single wideband oxygen sensor with the supporting controller and harness needed to integrate into any engine management platform or datalog system. The sensor operates across a broad AFR window (approximately 10:1 to 20:1), giving tuners unprecedented visibility into combustion efficiency and knock risk during acceleration, cruising, and idle conditions. The included display and digital outputs allow direct integration with aftermarket ECUs, laptop software, or gauge clusters, while the robust design and high-temperature rated construction ensure reliable operation in high-horsepower applications where exhaust temperatures and vibration can stress sensor life. Installation requires mounting the sensor in the exhaust manifold or header, positioning it before any catalytic converter to capture unfiltered post-combustion data.

This kit is ideal for engine builders, tuning shops, and dedicated enthusiasts who refuse to guess at fuel delivery. Whether you're validating a carb tune on a classic muscle car, optimizing a forced-induction setup, or logging baseline data before ECU refinement, the LM-2 Single Wideband O2 Sensor Kit delivers the precision feedback required to maximize power while protecting engine integrity. Most installations work with any four-cylinder, six-cylinder, or eight-cylinder configuration, and the flexible output options support both analog gauges and digital datalogging platforms. Proper AFR tuning at key load points can unlock 5–10% power gains and significantly improve cold-start driveability and emission compliance.
