AEM’s X-Series Wideband UEGO Air/Fuel Ratio Sensor Controller Gauges are built upon unique, patented 100% Digital technology (Patent 9,575,030) that makes them the fastest responding wideband air/fuel ratio controllers in independent testing*.

The X-Series Wideband UEGO AFR Sensor Controller Gauge (PN AEM 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.

Nice wedge pillow but not enough...
Color: Cool Grey, Size: 24x24x12 inch
It came compacted and when I opened it expanded almost immediately, maybe took like 20 minutes to fully decompress. Its soft and comfortable and the cover is really nice. But it does have a strong chemical smell, which is normal for this kind of brand new memory foam, I just put it on a table with a window open near it and after maybe 24 hours the smell was almost completely gone. The problem is that I bought this to have a elevated position when sleeping but the 30° are just not enough for me. I wish it was at least 45° but I could not find any pillow with that amount of degree... it's either 30° or like 75° in the other position. At the base of the pillow there is a little ridge that is comfortable for the lower back but makes me slide down in the middle of the night so I end up almost laying flat with my neck on the base ridge. With my slim build my lumbar area gets some nice support but makes my head almost have a "fall backwards" sensation, I like having my neck have a "push-forward" position with my pillow, but when adding another pillow to try and get to a comfortable position it only makes me slide down even more... :/

Very firm and durable
Color: Cool Grey, Size: 24x24x12 inch
worked great for husbands surgery recovery. Very affordable, firmness was great, looked nice on the bed and also used it for the grandkids when they were watching a movie. Moved around with ease. Didn't use it to sleep with all night though. He could only make it half the night but that wasn't the pillows fault. It was the cast on his arm. Definitely did its purpose after surgery and the need to sit up in bed more. highly recommend

Perfect. I used it when I was recovering from hip surgery. Relieved a lot of pain in my hip and knee at a time when I needed relief.

Comfortable, firm, great for positional sleep therapy
Color: Cool Grey, Size: 24x24x12 inch
This is just what I needed to breathe better in my sleep, my doctor recommended a pillow like this for sleep apnea symptoms. I have an upcoming surgery too, so i'm glad I was able to test it out a week prior and see how it can help me prop up in bed. Feeling better about my upcoming recovery knowing i'll have this great pillow to support me!

Literally perfect and exactly what I needed!
Color: Cool Grey, Size: 24x24x12 inch
I can't recommend this enough! It was exactly what i was looking for! I have an annoying habit of researching everything for months before I purchase something that will get used this often. I finally decided on this one and I was very pleasantly surprised. I needed a wedge pillow to put at my back while sitting in bed. Mostly for when I'm working on my laptop. This one was the perfect height and perfect fit for me.I'm a female that is 5'4 and weigh about 117pds. I wanted something firm enough to support my back, and this most certainly does! It had a very pleasant appearance with the light gray sides. It has a removable cover I can take off and wash when needed. It's portable enough to move from room to room, also works great on my couch and it has amazing versatility. It can also be used as a pillow for someone that might need to sleep at a slight incline. It also works if you need to prop your legs up. It came vacuum packed. Once opened It said to let is sit for at least 24-48 hrs to give it time to properly inflate. For me, It plumped right up immediately! Again, from someone that does her research, if your looking for something like this at a reasonable price, this is it!
