This creates the perception of a larger overall gauge, but in a common 52mm size for easy mounting. Its slim depth (less than one inch overall) and ultra-slim cup depth of .200-inches dramatically increases its application base and potential mounting locations.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe 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.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe gauge includes a 0-5v and RS232 Serial Port output for feedback control and data logging, and an AEMnet (CANbus) output for data logging. AEMnet allows additional X-Series Wideband Controllers to be daisy chained together (up to 16 cylinders) for recording AFR in multiple cylinders. It supports vehicle\/system voltages up to 16V, and can be used on EFI or carbureted applications, and dynamometers in applications using gasoline, methanol, ethanol, Diesel, propane, and CNG.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eX-DIGITAL TECHNOLOGY\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003eX-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.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eWHY RESPONSE TIME MATTERS\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003eFaster response time improves wideband feedback 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 (transport delay) can affect deadtime, it is not the only source. Often, the sensing elements response to the gas is the largest contributor to deadtime when an engine is in high RPM under load.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eWhen tuning an engine using wideband AFR feedback control on an inertia dyno, deadtime affects the data you are looking at because it is reported in a different operating location than when it actually occurred.\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003e\u003cstrong data-mce-fragment=\"1\"\u003eThis means with long deadtimes, whatever changes you make to the base fueling will likely be in the wrong location.\u003c\/strong\u003e\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003eThis can be particularly dangerous to high compression and high-boost forced induction vehicles, and EFI systems that use feedback control to auto-tune.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eReducing deadtime improves wideband feedback control, and can provide a safer, more powerful and accurate tune.\u003c\/strong\u003e\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003eAEM’s Wideband Controllers with X-Series digital technology can reduce deadtime and improve the performance of your vehicle through more accurate AFR tuning.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eFACTORY CALIBRATION RESISTOR OR FREE-AIR CAL, IT’S YOUR CHOICE!\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003eThe X-Series Wideband Gauge and X-Series Inline Controller support the popular Bosch 4.9LSU sensor and can utilize both the factory calibration resistor and free-air calibration methods**. This allows users to take advantage of the precise factory resistor calibration when a sensor is new but then allows for free-air calibrations if the user desires when the sensor ages.
