In independent testing against 17 competitor wideband controllers, the X-Series recorded the fastest response time.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThat matters because of deadtime: the delay between when exhaust gas composition actually changes and when the sensor reports it. Less deadtime means better feedback control and a safer, more accurate tune.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eThe packaging is what makes it fit where others won't.\u003c\/strong\u003e 52mm diameter with a seven-segment center display 87% larger than AEM's previous gauge, in a housing under one inch deep with a cup depth of only .200\". That opens up mounting locations a conventional gauge can't use.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eUser configurable from the gauge face\u003c\/strong\u003e — switch between AFR, Lambda, or O2%, change the center display to three or four digits, run a free-air calibration as the sensor ages, and change the CAN message ID when daisy-chaining multiple controllers.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eOutputs:\u003c\/strong\u003e 0-5V analog and RS232 for logging and feedback control, plus AEMnet CAN. Chain multiple controllers for up to 16 cylinders.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eAuto-dimming, locking connectors, and a single-board design for durability. Supports system voltage to 16V. Works on EFI and carbureted setups, and on gasoline including leaded race gas, methanol, ethanol, diesel, propane, and CNG.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eBlack bezel and black dual-faced faceplate included. Silver bezel with white faceplate available separately (30-0300-ACC). Includes Bosch LSU 4.9 sensor.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eSensors are wear items.\u003c\/strong\u003e Leaded fuel, oil contamination, and thermal shock all shorten their life — plan on replacement as maintenance.\u003c\/p\u003e","brand":"Street Strip Supply","offers":[{"title":"Default Title","offer_id":47280866787501,"sku":null,"price":230.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0779\/8105\/7197\/files\/aem30-0300.jpg?v=1787236348","url":"https:\/\/streetstripsupply.com\/products\/aem-x-series-wideband-uego-afr-sensor-controller-gauge","provider":"Street Strip Supply","version":"1.0","type":"link"}
