The LSU 4.9 is known for its reliability, accuracy, and fast response time. Unlike narrowband oxygen sensors that only read stoichiometric (14.7:1), wideband sensors accurately measure AFR across the entire range from rich to lean.\u003c\/p\u003e\u003ch4\u003eAccurate AFR Range 10:1 to 20:1:\u003c\/h4\u003e\u003cp\u003eThe gauge accurately displays air\/fuel ratios from 10:1 (very rich) to 20:1 (very lean), covering the entire range needed for tuning gasoline engines. This wide range allows you to monitor AFR during all driving conditions, from idle to wide-open throttle. Accurate AFR monitoring is essential for proper tuning and engine protection.\u003c\/p\u003e\u003ch4\u003e0-5V Analog Output for Data Logging:\u003c\/h4\u003e\u003cp\u003eThe gauge includes a 0-5V analog output that can be connected to an ECU, data logger, or other device for recording AFR data. This output allows you to log AFR alongside other engine parameters for comprehensive tuning and analysis.
