About this item
- The X-Series wideband UEGO AFR sensor controller gauge (PN 30-0300) features a modern, visually striking faceplate and new seven-segment, center display that is 87% larger than the 30-4110 AEM
- 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
- 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
- Faster response time improves wideband feedback control, and can provide a safer, more powerful and accurate tune
- When tuning an engine using wideband AFR feedback control on an inertia dyno, dead time affects the data you are looking at because it is reported in a different operating location than when it actually occurred

AEM 30-0300 X-Series Wideband UEGO AFR Sensor Controller Gauge
Description:
The X-Series Wideband UEGO AFR Sensor Controller Gauge (PN 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 X-Series Wideband 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.
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.
Factory calibration resistor or free-air cal, it’s your choice!: The 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. It’s the perfect marriage of simplicity and accuracy!
Features:
- X-Series Wideband UEGO AFR Controller Gauge were fastest responding wideband air/fuel ratio controllers in an independent test vs. 17 competitors wideband AFR controllers
- Includes Bosch 4.9LSU wideband UEGO sensor
- Factory calibrated resistor does not require free-air calibration, but technology allows for free-air calibration as sensor ages if user desires
- Compatible with vehicle/system voltages up to 16V
- 0-5V & RS232 output for data logging and feedback control, AEMnet (CANbus) for data logging and daisy-chaining multiple controllers up to 16 cylinders
- Can display AFR values in hundredths of %
- 52mm gauge diameter and slim 0.825” gauge depth
- Gauge cup depth only .200” deep!
- Auto dimming feature
- User configurable display via buttons on the gauge face for changing AFR values, Lambda and O2%, and 3- or 4-digit display
Product Description
AEM's X-Series wideband UEGO Air/Fuel ratio sensor controller gauges are built upon unique, patent-pending X-Digital technology that makes them the fastest responding wideband air/fuel ratio controllers in independent testing against 17 other wideband UEGO air/fuel controllers.

There was a problem filtering reviews right now. Please try again later.
I don't have it permanently mounted. I just ran the cable into the car so I could see it while driving. It was nice to confirm that at WOT I was running a touch rich. Perfect. Then I could take the O2 sensor out of the exhaust, put the bung plug back in, and save the sensor for the next time I need to tune.
I did previously weld in an 02 bung in my exhaust. I knew I would be running this at some point. Most muffler shops will do that for you for a few bucks.
I like the responsiveness of its output for tuning and the sweeping LED part of the display is useful for visualizing transients like acceleration enrichment when you don't have your laptop hooked up. The only negative about this unit is that the bezel is thick compared to most other wideband gauges, and based on the form factor of the actual gauge part the size of this part is pretty excessive. It's also gloss black, which doesn't match the satin/matte black of most interiors and gauge bezels, but I just had to remove the bezel and paint it to rectify this.
Tip: don't go through all of the hassle of running the wires and stuff until you bench test it out of the box. That way you know it's functioning before spending a few hours fighting with grommets and taking interior parts out to run wires cleanly.
