Product Description

The Innovate Motorsports 3877 LC-2 is a precision digital wideband controller kit designed for accurate air/fuel ratio monitoring across a wide range of engine and fuel types. Employing DirectDigital™ signal processing, the LC-2 delivers rapid, stable, and noise-resilient AFR data - ideal for tuning, dyno setups, or advanced engine management systems.

The kit includes a Bosch LSU 4.9 sensor, secure locking connectors, and flexible analog outputs that can be tuned or mapped to a variety of devices (ECU, gauges, data logger). The self-calibrating feature ensures consistent readings over changes in altitude, temperature, and sensor age, while the serial interface allows seamless integration into the Innovate MTS ecosystem.

Whether you're building a performance street car, track machine, or custom engine project, the LC-2 provides a reliable and configurable foundation for AFR feedback and tuning. Installation is straightforward - mount the controller in a protected area, wire power/ground/outputs, install the sensor bung in the exhaust, and perform the calibration process before running the engine.
