AEM's Wideband UEGO (Universal Exhaust Gas Oxygen, pronounced “You-Way-Go”) Controllers are powerful, cost-effective tuning tools that allow users to accurately monitor the Air/Fuel Ratio (AFR) of an engine. AEM was the first company to release a wideband AFR controller gauge with its Classic Digital Wideband and delivers the fastest-responding wideband air/fuel controller with its patented X-Series wideband technology. Both wideband gauge designs are 52mm to fit standard gauge pods and include everything you need to install them. Both designs include outputs to transmit AFR data to a logging device or engine management system.
