AEM Digital Wideband UEGO AFR Gauge - No SensorOur World famous Wideband O2 air fuel ratio UEGO gauge features a digital LED display and sweeping LED 'needle' that changes colors as AFR changes from rich to lean. A 52mm (2 1 16") gauge housing ensures that it will fit in most gauge pods and can be remotely mounted virtually anywhere. All AEM digital gauges feature a 0 5v analog output for use with data loggers and almost any engine management system. Each gauge comes with black and silver bezels

Our World-famous Wideband O2 air/fuel ratio UEGO gauge features a digital LED display and sweeping LED 'needle' that changes colors as AFR changes from rich to lean. A 52mm (2-1/16") gauge housing ensures that it will fit in most gauge pods and can be remotely mounted virtually anywhere. All AEM digital gauges feature a 0-5v analog output for use with data loggers and almost any engine management system. Each gauge comes with black and silver bezels and black and white faceplates for multiple color combinations and a custom look (a black Lambda faceplate and black and white Air/Fuel Ratio faceplates). The Bosch UEGO sensor gives the controller its speed and accuracy. The Bosch 4.9 LSU sensor used in the 30-4110 AEM Wideband UEGO AFR Controller Gauge has a faster light off time and draws less current than the 4.2 LSU sensor used with AEM’s 30-4100 Wideband UEGO Controller Gauge, which will be superseded to the 30-4110 gauge in August, 2014. The 4.9 LSU sensor features the same fuel compatibility as the 4.2 LSU and NEVER requires free-air calibration when used with AEM’s 30-4110 Wideband UEGO AFR Gauge. The 30-4110’s 4.9 LSU sensor uses a different connector than the connector used with the 4.2 LSU sensors included with the original 30-4100 gauge controller. The sensors are not interchangeable between the two gauge controllers in any way, including changing connectors on the gauges. The Wideband O2 air/fuel ratio UEGO gauge is a must if you want to maximize your engine's power and safety. When tuning an engine, accurate air/fuel ratio data is critical because running with too rich of an AFR can cause a loss of power, and running a lean AFR can result in serious engine damage. AEM's digital Wideband AFR UEGO gauge can quickly alert you to even a .1 change in air/fuel ratio and provide enough time to shut down an engine before damage occurs. Using the above sensors ensures that the factory sensor calibration is accurate and that the controller performs optimally. The use of any non-approved sensor may affect the controller's operation, and will void the warranty of the 30-4110NS. The new 30-4110NS Wideband UEGO Controller Gauge has the same display range and includes the same calibrated scale on its 0-5v output (10-20 AFR), for data logging or closed-loop feedback control when used with a standalone ECU. A serial output (RS232) is also included for outputting AFR values for data logging and feedback control. Gauge Readouts :

  • Center LED Readout Displays Gasoline Values from 10 to 18 :1 AFR
  • Outer LED Ring Displays Gasoline values from 11 to 16.75 :1 AFR
  • 0-5V Output Gasoline values from 10 to 20 :1 AFR
  • 0-5V Output E85 values from 6.6 to 13.2 :1 AFR
  • 0-5V Output Ethanol values from 6.14 to 12.3 :1 AFR
  • 0-5V Output Methanol values from 4.4 to 8.8 :1 AFR
  • 0-5V Output Lambda values from .68 to 1.36
  • Center LED Readout Displays Lambda values from .68 to 1.23
  • Outer LED Ring Displays Lambda values from .75 to 1.14

Nice patches -- Fair price -- has sulfur!
This is a review for the Halo Dot™ Pimple Patches for Face, Hydrocolloid Acne Patches with OptiMSM®, Visibly Shrinks Zit & Whitehead- Comes with Travel Essentials Inner Pouch (33 PATCHES) ($12.59) PROS: Price -- a fair deal for 33 patches and consistent with pricing of most other similar patches online. The inclusion of sulfur (this OptiMSM business) makes these unique also -- I can't seem to find others on Amazon with similar formulation, so these are intriguing. Sulfur is known for antimicrobial properties and can be helpful for zits and a little bit gentler on your skin than benzoyl peroxide or salicylic acid -- but anytime I put any sulfur stuff on zits that are above or around my eyes, it seems to migrate INTO my eyeball while I'm asleep and man is that uncomfortable. This little patch solves that dilemma nicely by keeping the sulfur put. CONS: none that I can see; these are a nice entry into the hydrocolloid acne patch space.

Disappointing results and poor adhesion.
I love Hydrocolloid pimple patches. I have used at least half of the brands available for sale and even the non brand ones. I’ve also used the hydrocolloid sheets and cut them to size and the hydrocolloid gel bandaids and used for pimple patches. I love how they help along the healing and keep me from picking at the pimple. This brand I wasn’t impressed by. None of them stayed on my face for half the night. The one that remained in place the longest out of the 4, didn’t show any signs of improvement. The longest they kept in place was 3 hours. I had to reapply and I still handbrake noticed any signs of healing after using one full sheet on 4 smaller sized blemishes because the adhesive wasn’t working.

Stops Me From Picking and Actually Works
As a woman in my 40s, I never would have guessed I’d still need pimple patches, yet the occasional zit still pops up — and these things are like magic. They work really well, blend into my fair/light skin nicely, and are barely noticeable at a quick glance. I’m also a terrible picker, and picking is so bad for your skin, so I love that these keep me from messing with pimples while doing all the work for me overnight. I’m always grossly fascinated by how much gunk they pull out by morning. Very happy to have these in my little skincare emergency arsenal.

Camouflages well with the skin and sticks long enough
I was excited to try these Halo Dot patches because I was having some breakouts before a wedding I had to attend. I put these on three nights before the wedding only at nights and left them on until the morning. I washed my face the 1st night, yet the second night I did not and it still attached (mind that I have a very oily face by the end of the day). With every application I saw good results as the breakouts were being reduced with each use. It is easy to put on and to carry out if you need to travel because it comes in two separate little envelope like package that you can put in a backpack/purse. These are thin and are almost not visible.

Easy to Use and Surprisingly Effective
Even though I am well past the age when I thought breakouts would stop happening, I still get the occasional pimple. As luck would have it, I felt one starting to pop up on my cheek the day after these Halo Dot Pimple Patches arrived. Before bed, after washing and thoroughly drying my face, I applied one of the patches. It peeled easily from the backing sheet, and when I realized I had not placed it quite right, I was pleasantly surprised that I could lift and reposition it without any trouble. What really impressed me was how well it blended into my skin. I was only wearing it overnight, but honestly, I do not think anyone would have noticed it unless they were looking very closely. In fact, I forgot I even had it on until I looked in the mirror the next morning. The patch peeled off easily and had clearly pulled some of the buildup from the blemish overnight. There was no redness or irritation afterward, and the spot looked dramatically improved by morning. The only downside for me is the price, especially since the package contains just 33 patches. That said, if they continue to work this well, I would definitely consider purchasing them again.
