AEM X-Series Wideband UEGO AFR Gauge & ControllerThe X Series Wideband UEGO AFR Sensor Controller Gauge 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 Gauges 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

The X-Series Wideband UEGO AFR Sensor Controller Gauge 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 Gauges 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 gauge face that allow 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 faceplate 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 gauges robustness.

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.

Great for small apartment!
Purchased for a first apartment. It was a little more complicated to put together, but not too terribly difficult. It was perfect for the small space. Has been the perfect gift!

Perfect for organizing kids’ essentials
Size: with legs
I really like this EXPERLAM 8 Cube Storage Organizer. It was fairly easy to assemble and feels stable once put together. The design is simple and clean, so it fits nicely in our home. I’m using it mainly for my children’s toys, and it works great. It helps keep everything in one place instead of toys being all over the room. The cube size is very practical for different types of toys, books, and storage bins. Overall, it’s very useful for organizing a kids’ space and makes cleaning up so much easier. Definitely happy with this purchase.

Great storage for kids’ room!
Size: with base, Size: with base
It took me about 30-40 minutes to assemble, and it wasn't difficult at all. It fits perfectly in the kids' room, and finally, all the toys aren't scattered all over the floor 🙌 The baskets are roomy, they hold a lot of stuff, and my kids can easily pick up their toys and put them back (well... sometimes 😂). Plus, it looks very neat and modern. I'm very happy with the purchase; the room is much more organized now 👍

Not for storage
Size: with legs
It’s too small to use as effective storage. It is mostly decor.
