8.50:1 to 18:1 AFR Scale - Black Bezel - Black Face. AEM's X-Series Wideband Air/Fuel Ratio Sensor Controllers are built upon unique, patented X-Digital technology (Patent 9,575,030), making them the fastest responding wideband air/fuel ratio controllers in independent testing*.AEM co-developed its new wideband sensor with global automotive supplier FAE, culminating in a new design that has a faster response time and is less prone to failure in high performance vehicles. It can be used on EFI or carbureted applications, and in fuel systems using gasoline (including leaded race gas), methanol, ethanol, diesel, propane, and CNG.The X-Series Wideband AFR Gauge (PN AEM 30-0300) mounting surface measures 2 1/16th-inch (52mm) in diameter and features a modern center display that is 87% larger than the 30-4110 AEM Wideband Gauge's center display. Its slim depth (less than one inch overall) dramatically increases its application base and potential mounting locations.The AEM Wideband X-Series AFR Gauge has a user configurable display via buttons on the gauge face that allows you to change between AFR, Lambda, or O2%, change the center display to three or four digits, perform a free-air calibration if desired, and change the CAN message ID when linking multiple X-Series Wideband Controllers.X-DIGITAL TECHNOLOGYX-Digital wideband technology gives these controllers the ability to read and report values that other controllers do not, which can deliver more optimized engine tuning and a safer overall operating condition. The controller's high-speed digital implementation ensures no loss of signal fidelity and full transient response, making it able to identify the slightest fluctuations in AFR and output them in full value.WHY RESPONSE TIME MATTERSFaster response time improves wideband response control, and can provide a safer, more powerful and accurate tune. 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 response 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 response control.
