The X-Series Wideband UEGO AFR Sensor Controller Gauge (PN AEM 30-0300) measures 2 1/16th-inch (52mm) in diameter and features a modern, visually striking faceplate and new seven-segment center display that is 87% larger than the 30-4110 AEM Wideband Gauge's center display. 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. 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 gauge's durability. The 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. X-DIGITAL TECHNOLOGY X-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 MATTERS Faster 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. When 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. This means with long deadtimes, whatever changes you make to the base fueling will likely be in the wrong location. This can be particularly dangerous to high compression and high-boost forced induction vehicles, and EFI systems that use feedback control to auto-tune. Reducing deadtime improves wideband feedback control, and can provide a safer, more powerful and accurate tune.

The 30-0334 X-Series OBDII Wideband Gauge is validated to work with DiabloSport in Tune 3, Trinity 2, EFILive, HPTuners and DashPaq software. The X-Series Wideband AFR OBDII Gauge includes an OBDII pass-through connector and 4.9LSU sensor that can be free-air calibrated or used with the factory resistor calibration. Additional wiring for a 0-5v or RS232 Serial output can be added by the user for outputting to a data logger. This OBDII pass-through capability replaces the traditional AEMnet stream available in the 30-0300 X-Series Wideband AFR Gauge Controller. OBDII CAN-bus OUTPUT The OBDII output simulates an auxiliary ECU signal when plugged into a vehicle's OBD port, which requires a unique address from the other ECUs already on a vehicle's network. AEM's default OBDII CAN address will work with most popular vehicles and adjustments should not be necessary. However, AEM has provided OBDII address programmability through the buttons on the gauge face if a different address other than the default address is required, allowing users to program ECU #, Parameter Identification (PID), Message Identifier, and Bit Rate.
