AEM's Wideband Controllers with X-Digital technology can reduce deadtime and improve the performance of your vehicle through more accurate AFR tuning. Deadtime is the delay between when exhaust gas composition changes and when that change is reported by the O2 sensor. While flow of exhaust gases can affect deadtime, it is not the only source. Often, the sensing element’s response to the gas is the largest contributor to deadtime.When tuning an engine using wideband AFR feedback control, deadtime affects the data you are looking at because it is reported in a different operating location than when it occurred. This means whatever changes you make to the base fueling will likely be in the wrong timeframe. This can be particularly dangerous to high cylinder pressure applications, and EFI systems that use feedback control.","brand":"AEM","offers":[{"title":"Default Title","offer_id":46086089900181,"sku":"AEM30-0300","price":233.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0623\/3777\/7813\/files\/2f94eb85cadb0b78d694964be88e6514.jpg?v=1749513691"},{"product_id":"aem-x-series-wideband-uego-afr-sensor-controller-gauge-accessory-kit","title":"AEM X-Series Wideband UEGO AFR Sensor Controller Gauge Accessory Kit","description":"The AEM Wideband X-Series UEGO AFR Gauge has a user configurable display via buttons on the gauge face that allows you to change AFR values for different fuels, Lambda or O2%, change the center display to three or four digits, perform a free-air calibration if desired as the sensor ages, and change the CAN message ID when linking multiple X-Series Inline Controllers or X-Series Controller Gauges. A black bezel and black dual-faced faceplate for air\/fuel and Lambda are included, and an optional silver bezel with white dual-faced air\/fuel and Lambda faceplate is available (PN 30-0300-ACC, sold separately). An Auto Dimming feature is included. Locking connectors ensure a positive connection between the harnesses and gauge and a new single board design adds to the new gauge's durability.","brand":"AEM","offers":[{"title":"Default Title","offer_id":46086089965717,"sku":"AEM30-0300-ACC","price":15.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0623\/3777\/7813\/files\/d06cb7f2f14275549593ee5aa98d23f0.jpg?v=1749513692"},{"product_id":"aem-x-series-obdii-wideband-uego-afr-sensor-controller-gauge","title":"AEM X-Series OBDII Wideband UEGO AFR Sensor Controller Gauge","description":"Accurate AFR data is critical when tuning an engine. 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.","brand":"AEM","offers":[{"title":"Default Title","offer_id":46086091538581,"sku":"AEM30-0334","price":304.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0623\/3777\/7813\/files\/8ed9e396e386818b638ea93f78107ecc_02839eb4-5d9b-4c40-ba4a-29a4ce35eccc.jpg?v=1749513708"},{"product_id":"aem-sensor-harness-for-30-0300-x-series-wideband-gauge","title":"AEM Sensor Harness for 30-0300 X-Series Wideband Gauge","description":"Replacement Wiring Harnesses, Sensor Harness for X-Series Wideband Gauge 30-0300 and 30-0334","brand":"AEM","offers":[{"title":"Default Title","offer_id":46086097240213,"sku":"AEM30-3427","price":36.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0623\/3777\/7813\/files\/c06477df555ef325aac06e554994fc50.jpg?v=1749513776"},{"product_id":"aem-replacement-sensor-harness-for-digital-wideband-gauge-30-4110","title":"AEM Replacement Sensor Harness for Digital Wideband Gauge (30-4110)","description":"AEM Replacement Sensor Harness for Digital Wideband Gauge (30-4110)","brand":"AEM","offers":[{"title":"Default Title","offer_id":46086097371285,"sku":"AEM30-3441","price":43.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0623\/3777\/7813\/files\/8b757703f286253a75482835b393e250.jpg?v=1749513778"},{"product_id":"aem-power-harness-for-30-0300-x-series-wideband-gauge","title":"AEM Power Harness for 30-0300 X-Series Wideband Gauge","description":"· 3 different forms of communication, CAN, Analog, and Serial","brand":"AEM","offers":[{"title":"Default Title","offer_id":46086097600661,"sku":"AEM30-3459","price":22.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0623\/3777\/7813\/files\/a8608285942fec3dd90bdb2627273dcc.jpg?v=1749513780"}],"url":"https:\/\/www.9tperformance.com\/en-ca\/collections\/air-fuel-ration-gauges.oembed","provider":"9T Performance","version":"1.0","type":"link"}
