This is a manual for the LC-2 digital air/fuel ratio (Lambda) sensor controller, which details the product's features and characteristics.
The LC-2 is a controller designed to manage a wideband O2 lambda sensor for measuring oxygen content in exhaust gases. It features a status light to indicate operational states such as initialization, warm-up, calibration, or error conditions, and provides configurable analog outputs for external devices like data loggers and AFR gauges.
The document details the mounting and wiring procedures, emphasizing the need to mount the controller in a dry location away from RF/EMI sources and to route the sensor cable carefully to avoid heat damage. It also explains the sensor placement guidelines, calibration schedule for different vehicle types, and instructions for using the LogWorks 3 and LM Programmer software.
