Description

AEM Electronics Gauge OBDII Wideband AFRAEM'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

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 optimally tuned.

CAN I CHANGE THE AEM UEGO SENSOR'S CONNECTOR?
No. There is a laser-etched, calibrated resistor in the sensor's connector body. This resistor is specifically created for the exact sensor that it is attached to. Modifying this will invalidate the sensor's output.

Not an exact equivalent to the original two piece design
Size: For 1998-2001 E46 Sedan 4-Door, Color: Chrome
Not an exact equivalent to the original two piece design. It won't snap in place as a direct replacement and required some glue. Not sure how long that will last.

Nice for the price

Overall, super happy with it. Didn't expect much since a genuine one is 2-3x the price, but it fits decently (could be better) and isnt super flimsy. It isn't perfect, but its the best youre going to get without buying a genuine OEM one.

Don’t waste your money on OEM
This replacement filter fits perfectly. Who care that it doesn’t say “Honda” on the filter. I really don’t think my car cares or knows the difference. It’s took all of 10 minutes to change. If you are worried about doing it yourself…then got to YouTube. There are literally dozens of videos showing you how easy it is. But if going to the dealer, spending your time and wasting money makes you feel better, then have fun with that. You can get all the materials you need to do the basic maintenance for your car and save. And don’t believe the BS, doing the work yourself doesn’t void your warranty.
