Built around a robust LSU 4.9-style sensing element, this 5-wire sensor is crafted for reliable signal integrity and steady performance across a range of tuning scenarios.\u003c\/p\u003e\n  \u003ch2\u003eOverview\u003c\/h2\u003e\n  \u003cp\u003eEngineered to integrate smoothly with AEM controllers such as the 30-4110, 30-0300, and 30-0310, this sensor also complements the X Series AFR Inline Controller. The 5-wire configuration supports dedicated power, ground, signal, and heater connections, helping to maintain a stable response under varying temperatures and exhaust conditions. Its design focuses on delivering a consistent air-fuel signal that a tuner can read confidently during bench setup, road testing, or track sessions.\u003c\/p\u003e\n  \u003ch2\u003eKey benefits\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eLSU 4.9 sensing element for high-resolution lambda data\u003c\/li\u003e\n    \u003cli\u003e5-wire design for reliable heater and signal integrity\u003c\/li\u003e\n    \u003cli\u003eDirect compatibility with AEM 30-4110, 30-0300, and 30-0310 controllers\u003c\/li\u003e\n    \u003cli\u003eSeamless pairing with the X Series UEGO Inline Controller for streamlined tuning\u003c\/li\u003e\n    \u003cli\u003eRugged construction intended for repeated use in street and track environments\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003ch2\u003eReal-world use cases\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eData-driven fueling adjustments during street tuning or on-track testing\u003c\/li\u003e\n    \u003cli\u003eMonitoring AFR to understand how each change affects exhaust flow and combustion stability\u003c\/li\u003e\n    \u003cli\u003eQuick reference readings during installation or rerouting experiments, with a clear signal path to the ECU\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003ch2\u003eInstallation and compatibility notes\u003c\/h2\u003e\n  \u003cp\u003eThe sensor is designed to work alongside popular AEM controllers and the X Series inline device.
