AEM's X-Series OBDII Wideband UEGO AFR Sensor Controller Gauge (PN 30-0334) provides tuners who are using piggyback tuning modules or open source software with the ability to view AFR through the factory CAN-bus stream that is output by the factory ECU, and deliver the most accurate, safe and powerful tune. The 30-0334 X-Series OBDII Wideband Gauge is validated to work with EFILive, HPTuners and DashDaq software.

The X-Series Wideband AFR OBDII Gauge includes an OBDII pass-through connector and Bosch 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.

PATENTED X-DIGITAL TECHNOLOGY – It’s The Fastest
X-Series Widebands are the fastest responding wideband air/fuel ratio controllers in independent testing against 17 other wideband UEGO air/fuel controllers.* The controller’s high speed, patented, X-Digital technology (Patent 9,575,030) 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 reduce deadtime and can improve the performance of your vehicle through more accurate AFR tuning.

FACTORY CALIBRATION RESISTOR OR FREE-AIR CAL, IT’S YOUR CHOICE!
X-Series Wideband Gauges and the 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!

WHAT IS A WIDEBAND UEGO AIR/FUEL CONTROLLER?
AEM's Wideband UEGO (Universal Exhaust Gas Oxygen, pronounced “You-Way-Go”) Controllers are powerful, cost effective tuning tools that allow users to accurately monitor the Air/Fuel Ratio (AFR) of their engine.

WHY USE A WIDEBAND AIR/FUEL CONTROLLER?
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 op...

Easy to use Plug and Play
Size: USB C to Ethernet Adapter
The item works great. I was having issues with video conference calls even with strong wifi in my house. I bought this adapter due to my HP laptop not having an Ethernet port. This worked great right out of the box. It was detected automatically and as soon as I plugged the Ethernet cable into the adapter, my laptop immediately switched over to that and my internet became more stable.

It's functional but not as fast as I expected.
Size: USB C to Ethernet Adapter
For Android phone Samsung Flagship Galaxy Series phones... at best getting 136 Mbps, which is 0.136 Gbps. But it is working and allowing me to transfer files within my network. No where near a Gigabit transfer. I will likely keep it because I have another use case for it (a faulty Ethernet on a laptop) and don't get me started with the abyssal wifi speeds on laptops. This deserves at best 4 stars.

Worth every penny
Size: USB C to Ethernet Adapter
This adapter provides a stable, hardwired connection when Wi-Fi is not fast enough for heavy law school research. It is strictly plug and play, requiring no software installation. The weight is negligible, making it easy to keep in my bag for campus. Given the excellent build quality and consistent functionality without any drop-offs, it offers solid value for money. It’s perfectly versatile for numerous uses (keeps me from having to use like 3 other dongles)
