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 fit, true to size. I am 6'2" 217 lbs and bought the XL. The color is just as expected and the cut feels and looks tailored. This suit looks like aand feels expensive while being extremely budget friendly.

5’-11”, 185 lbs, Size- Large
5”-11”, 185 lbs, size Large. Suit jacket fits good and has some weight to it. My chest is a little bigger proportionally for my size but if I go with a size up, the jacket would be too big. Vest fits good but appears to be XL though it is labeled L. Not a big deal. Pants are also a good fit. Waistband is not too tight or too loose around my waist. Pant length is a little long but still a good fit. I normally wear 34x34 pants.
