AEM Electronics UEGO X-Series Wideband Controller w/ Gauge Kit
Universal
Features & Product Details
When it's time to get a new wideband O2 meter, or to replace your current wideband, then you might be pretty happy with the new AEM X-Series UGEO Wideband Controller Gauge. Wideband gauges should become standard in turbocharged vehicles because they produce a value (AFR) to let the driver know that they are running on a proper tune. Over time, things such as a boost leak, vacuum leak, malfunctioned components, or a bad tune can cause your vehicle to run lean or rich under boost. If you're running lean under boost then your motor won't last much longer. But this wideband is not just limited to turbocharged vehicles, it can be used on normally aspirated applications that could be making substantial amounts of power through bolt-ons.
The X-Series gauge uses the latest in patent-pending digital technology to deliver faster response time with AFR readings. This wideband gauge features a weather resistant low-profile gauge that responds quickly to allow tuners to optimize on tunability. And because of the gauge's high-speed digital implementation, it ensures that there will be no loss of signal and response which is very important for a solid tune.
Everything will be included with this gauge to make it ready for installation which includes the Bosch 4.9LSU UEGO sensor, along with the appropriate contoller and wiring. A bung provision is also provided for the user to have welded onto their preferred location.

Easy to install , easy instructions ,
Great wideband and very easy to install.
Special thanks to RSD chat folks! They helped me get this and other items in promptly! If you're like most people and don't like paying lots of cash for dyno tuning sessions every time there's a car mod, this is a MUST have for your Subie. This will allow for good e-tuning, which is a good alternative to paying $600+ for a dyno tune session when all you're adding is an intake (for instance). I had mine professionally installed so it feeds AFR to the car's wiring harness, so it can be easily logged via Cobb Access Port (version 3 ONLY). Here's the link for the setup if anyone is curious or interested: https://forums.nasioc.com/forums/showthread.php?t=2805570 This item is somewhat overpriced. There are other brands that have the same specs and lot cheaper. That being said, it comes with all hardware for the installation. Last, this gauge is NOT COMPATIBLE with the SMY ClusterMaker Dual Gauge Pod 52mm (SMY SMYCLSTR1). If you get this gauge, I strongly suggest getting a different gauge pod than SMY. The SMY is very popular because it looks OEM, but the MAJOR design flaw is that the only thing holding the wideband in place is a piece of rubber band!! It easily pops off because the way the AEM wideband is designed. I'm very unhappy about how mine fit (it looks great), BUT it continuously pops off as driving over bumpy roads because the only thing holding in place is a piece of rubber band.
Love this gauge. It was an easy install and keeps my engine safe.
i had been putting off getting a wideband due to thinking install would be complicated but i finally jumped the gun. THIS IS BY FAR THE EASIEST THING I HAVE EVER INSTALLED. If you plan to run the gauge standalone ( not hooking up to any aftermarket ecu/tuner) you literally just need 12v power and ground, pop the sensor in, snake some wires, and your set. looks quality, and works amazing, i highly recommend this to anyone considering a wideband, super easy install and mad benefits of having one.

A: We haven't tested it, but it should. The mounting bracket on this gauge should still tighten down to the CubbyPod mounts.

A: The X-Series gauge has a digital read out, and can read a wider range (7.4:1 to 22.4:1) The other gauge 30-4110, has an interchangeable faceplate, can read between 10.1:1 and 20.1:1, and has a digital needle that sweeps around the outside of the gauge to indicate the reading. I wouldn't say one is better than the other, it's a matter of what gauge display you would like. They both have the same sensor, and will have the same information. If you are running E85, the X-Series might be a better option.
