Running rich (very low air\/fuel ratio, excessive fuel) can cause a loss in power, while running too lean (very high air\/fuel ratio, not enough fuel) may result in serious engine damage. Using a wideband air\/fuel controller during the tuning process allows you to monitor AFR and adjust tuning parameters to optimize them for maximum power and efficiency. AEM has a comprehensive line of highly accurate, reliable wideband air\/fuel controllers that can help ensure your vehicle is optimally tuned.\u003c\/p\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/0be145aaf5f7e38fed1da9a312784556.PDF\"\u003eInstallation Instructions\u003c\/a\u003e\u003cbr\u003e\u003cul\u003e\n\u003cli\u003eX-Series Wideband UEGO AFR Controllers Gauge were fastest responding wideband air\/fuel ratio controllers in an independent test vs. 17 competitors wideband AFR controllers\u003c\/li\u003e\n\u003cli\u003e0-5V \u0026amp; RS232 output for data logging and feedback control, AEMnet (CANbus) for data logging and daisy-chaining multiple controllers up to 16 cylinders\u003c\/li\u003e\n\u003cli\u003eFactory calibrated resistor does not require free-air calibration, but technology allows for free-air calibration as sensor ages if user desires\u003c\/li\u003e\n\u003cli\u003eBlack bezel and black dual faced faceplate included (gauge only, silver bezel\/white gauge option sold separately, PN 30-0300-ACC)\u003c\/li\u003e\n\u003cli\u003eUser configurable display via buttons on the gauge face for changing AFR values, Lambda and O2%, and 3- or 4-digit display\u003c\/li\u003e\n\u003cli\u003eOBD-II Output; CAN based compatible with 2008 or newer vehicles\u003c\/li\u003e\n\u003cli\u003ePatented X-Digital wideband technology (Patent 9,575,030)\u003c\/li\u003e\n\u003cli\u003eCompatible with vehicle\/system voltages up to 16V\u003c\/li\u003e\n\u003cli\u003e52mm gauge diameter and slim 0.825\" gauge depth\u003c\/li\u003e\n\u003cli\u003eIncludes Bosch 4.9LSU wideband UEGO sensor\u003c\/li\u003e\n\u003cli\u003eCan display AFR values in hundredths of %\u003c\/li\u003e\n\u003cli\u003eGauge cup depth only .200\" deep\u003c\/li\u003e\n\u003cli\u003eAuto dimming feature\u003c\/li\u003e\n\u003cli\u003eLocking connectors\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AEM","offers":[{"title":"Default Title","offer_id":44130717237383,"sku":"AEM30-0334","price":291.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/4855\/4631\/files\/8980583ec36874d75fc8cbcf9d691b0dL.jpg?v=1773144079","url":"https:\/\/fullsenddiesel.com\/products\/aem-x-series-obdii-wideband-uego-afr-sensor-controller-gauge","provider":"Full Send Diesel","version":"1.0","type":"link"}
