For fast response times, AEM X-Series wideband UEGO air/fuel sensor controller gauges are the way to go! Built on the unique, patent-pending X-Digital technology, they report accurate information quickly— enabling you to tune your engine more efficiently. These gauges have modern, visually striking faceplates with 7-segment center displays that are 87 percent larger. They're ultra-slim and come with black bezels and black dual-faced faceplates for air/fuel and Lambda. The displays are user-configurable and feature auto dimming.

Additional features:

* 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 16 V
* 0-5 V and 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 a percent
* 52mm gauge diameter and slim 0.825 in. gauge depth
* Gauge cup depth only .200 in. deep
* Locking connectors

Questions & Answers Ask a Product Question
Q:

do I need two kits one for left side and one for right, or just two o2 sensors??

Asked by RICHARD on August 16, 2017

A:

One kit for each side. However I would look into a kit that has a dual sensor input.

Answer This Question

Q:

I have a 2006 LS2 GTO.Rear O2 sensors are turned off.I would like to know if I could thread the WB O2 fitting into the rear sensor O2 bung and get an accurate reading.I'm running long tube headers with catless mid pipes.

Asked by RANDY on November 20, 2017

A:

Hi Randy, thanks for your question. Ideally, you want to mount the sensor 18-24" from the exhaust ports to minimize deadtime, but if you have unused bungs available on your headers there should be no problem mounting the sensors in them. Please make sure that the bungs have been installed so that the sensors are positioned at an angle per the instructions. This will prevent condensation buildup on the sensor when the engine is turned off, which will ensure the life of the sensor is not shortened prematurely.

Answer This Question

Q:

How close can you install this 02 sensor to the cars
main ecm 02 sensor ? From the end of my shorty headers
to the top of the cats room is very tight! I may have to install this 02 sensor after the cats .

Asked by TOM on November 29, 2017

A:

Hi Tom,
You will want to install the sensor 18"-24" down the collector pipe, at an angle that is illustrated in the instructions to prevent condensation build up on the sensor when the vehicle is off. You can install it further but it will affect the deadtime slightly.

Answer This Question

Q:

Does this work well with boosted applications? And is it compatible with ms1

Asked by BLAKE on January 04, 2018

A:

Hello Blake and thanks for your question. The 30-0300 X-Series Wideband UEGO AFR Gauge performs the same whether on a naturally aspirated or boosted engine. You will need to mount the sensor post turbo per the instructions. X-Series Widebands have a 20ms average response time, which is independently tested to be the fastest available wideband against 17 other controllers. This allows the X-Series to report transient changes in AFR that other controllers may miss, which will provide you with data and/or feedback control to get the best possible tune. As long as the MS1 has analog inputs there should be no issue connecting the X-Series Wideband Gauge to it, since it has a 0-5V analog output for logging and feedback control. We also publish our CAN bus protocol (AEMnet), so if MS has provisions for CAN and accepts 3rd party CAN data, then you can also configure it to the MS1 via CAN. You will need to check with them on that, though.
