Description

AEM Digital Wideband UEGO GaugeAEM's legendary Digital Wideband O2 AFR UEGO Gauge is a wideband UEGO air fuel ratio controller (AFR) and gauge in one. It unites accuracy, speed and control with an easy to read, digital LED display and sweeping LED "needle" that changes colors as AFR changes from rich to lean. NOTE: The 30 4100 Wideband UEGO Gauge Controller that uses the 4. 2 LSU sensor will be superseded to the 30 4110 Wideband UEGO Gauge Controller that uses the 4. 9 LSU sensor

AEM's legendary Digital Wideband O2 AFR UEGO Gauge is a wideband UEGO air/fuel ratio controller (AFR) and gauge in one. It unites accuracy, speed and control with an easy to read, digital LED display and sweeping LED "needle" that changes colors as AFR changes from rich to lean. NOTE: The 30-4100 Wideband UEGO Gauge Controller that uses the 4.2 LSU sensor will be superseded to the 30-4110 Wideband UEGO Gauge Controller that uses the 4.9 LSU sensor in August 2014. Instructions for the 30-4100 will still be available in the Instructions tab after this change. WHAT IS A WIDEBAND UEGO AIR/FUEL CONTROLLER? AEM's Wideband UEGO (Universal Exhaust Gas Oxygen, pronounced "You-Way-Go") Controllers are powerful, cost-effective tuning tools that allow users to accurately monitor the Air/Fuel Ratio (AFR) of their engine. WHY USE A WIDEBAND AIR/FUEL CONTROLLER? Accurate AFR data is critical when tuning an engine. Running rich (very low air/fuel ratio, excessive fuel) can cause a loss in power, while running too lean (very high air/fuel ratio, not enough fuel) may result in serious engine damage. Using a wideband air/fuel controller during the tuning process allows you to monitor AFR and adjust tuning parameters to optimize them for maximum power and efficiency. AEM has a comprehensive line of highly accurate, reliable wideband air/fuel controllers that can help ensure your vehicle is optimally tuned. WHAT IS FREE-AIR CALIBRATION? Some of our competitors require that you frequently perform a free-air calibration procedure to calibrate their O2 sensors. This process involves removing the sensor from the bung while still connected to the controller device, then waving the sensor in the air so it can read atmospheric O2 levels. We use 4.9 LSU sensors in our wideband controllers. Our sensors are individually laboratory-calibrated and never require free air calibration!

Great shorts.
Fit Type: 7" Inseam, Size: Large, Color: Dark Grey
Great shorts for working out in. They’re nice and light and I like how the pockets have zippers. I purchased blue ones first and I liked them so much. I ordered the gray ones.

Look great and feel wonderful for the gym.
Fit Type: 7" Inseam, Size: XX-Large, Color: Grey Camo
My favorite gym shorts. Not a ton of pockets, but the front pockets zip closed and fit my phone and headphones well. They dry very fast, look great, and are light enough and comfortable enough to work out in.

Great feel and color
Size: Medium, Color: Ocean Depths, Size: Medium, Color: Ocean Depths
Absolutely love this tank top! The color is gorgeous and exactly like the pictures — super vibrant and flattering. The ribbed material feels soft but still has enough stretch to hug in all the right places. I also really like the built-in padding and racerback style because it makes it easy to wear without needing extra layers. The only thing I would mention is that it runs a little small, especially if you want a more relaxed fit. I’d recommend sizing up if you’re between sizes. Other than that, it’s a great basic top that looks cute dressed up or casual!

Vibrant Racer Back Tank !!!
Size: X-Small, Color: Hot Pink, Size: X-Small, Color: Hot Pink
I purchased this Danysu V Neck Racer Back Tank Top for Women Padded Ribbed Long Tank Fitted Basic Cami Tops to wear under my off-shoulder top for an upcoming 80’s dance party, and it works perfectly for what I needed! The bright pink color really pops and adds the perfect retro accent to my outfit. I intentionally ordered the XS because I did not want it to fit loose under my top, and it definitely gives a snug, fitted look. The ribbed material is soft and stretchy, and the built-in padding is a nice bonus. I would recommend sizing up if you plan to wear it alone or if you are curvier, as the XS runs very tight. However, for layering under another top as I did, it worked out exactly the way I wanted. Super cute, flattering, and great for layering or workouts!

My new Favourite Summer Tank Top - padded cup (no shelf bra!)
Size: X-Small, Color: Color Block Black, Size: X-Small, Color: Color Block Black
Cutest tank top, my new summer go-to. I was looking and searching high and low for a tank top which had padded cups without the shelf bra. Shelf bras are so uncomfortable with their elastic bands and are even worse in the summer, sweaty sun. I wanted something breathable, movable, and with just a bit of padding to cover the nipples and add the slightest big of shape. If you are large breasted these built in cups might not be the best for you, but as a smaller breasted lady these are perfect. The cups are not over the top bulky, but also they are not meant to really add "support" (for those who are looking for support this wouldn't be the tank for you. Think lightly padded!) The material is super soft and the length comes down to the hips. The tank doesn't ride up, so you're not always having to pull them down and adjust, and so you could wear them for both workouts or for casual summer evenings. I bought size XS and I am 5'1, 97 lbs. I was wondering if I should go to a size S because it wasn't clear by some of the reviews, but I'm glad I bought the XS because the shoulder strap is also the perfect length (not too baggy but also not super tight). Read the sizing chart before you buy - they are true to the size indicated on the sizing chart. Some have said theirs didn't come with padding, or the stitching was poor, but the ones I've received are totally fine. This tank is just plain-old comfortable any way you look at it. I'll be buying more colours!
