Reads nice and consistent!
If you're looking at this, you have probably souped-up your car and need to keep an eye on your air-fuel ratios.This does that, and does it well. Readings are very consistent and this gauge has a reputation for accuracy.You can use this gauge and also hook it up to a standalone engine management system for data-logging. The gauge housing is plastic...but it doesn't need to be a tank. The wiring is all very good, and not cheap-feeling in any way. Installation was also quite easy...you do need to have a +12V ignition source...and FUSE IT. If you melt a wire going to the O2 sensor, you could ground on the chassis and that could be real bad. This did not come with a fuse, but Autozone has solutions for that.There are silver and black surrounds. The bezel is silver and black for AFR, or black for Lambda. There's a light sensor in the gauge, so it will get darker at night and not flood your interior with light. The sampling rate is quite high, so...

Great
Works great, easy to install, looks good, using on my procharged f150, plug and play for the most part. A little wiring, driving, and welding and your all set.

Product Description

A wideband UEGO sensor controller accurately monitors Air/Fuel ratios (AFR) during the tuning process to prevent a lean fuel mixture, which could lead to engine damage. AEM has combined its single-channel wideband UEGO controller and gauge display into one unit, uniting unsurpassed AFR accuracy and control with an easy-to-read interface. AEM’s Gauge-Type Wideband UEGO Controller features a digital LED display and sweeping LED “needle” that changes colors as AFR changes from rich to lean. The unit’s 52mm (2-1/16”) gauge housing fits in most gauge pods and can be remotely mounted virtually anywhere. Top to learn more

Great product , fast shipping and easy installation
AEM 30-4100 UEGO was very easy to install. I had it up and running in no time and also made a RS232 wire as well as a Firewire IEEE 1394 (male to male) for dataloging. The RS232 was connected to a Hyper Terminal program found in Windows Xp(Only optional and was used to double check my formula in Live Link..I did not datalog by using both cable at the same time) . The IEEE 1394 cable was connected to a Xcal3 from SCT and used with Live Link to datalog more efficient. I hooked up the 12v cable for the gauge on a 12v ignition only wire on the car and a ground under the dash. Simple as that. Also has lights integrated in the 12v and ground circuit so you don't have to mess with also hooking up the lights as in other gauges. Only downside is the Bosch O2 sensor ,which I have heard that they go bad pretty quick , especially if your car is running to rich .The cost for it is about $60.

Works good, highly sensitive
I removed all the computer controls on my 81 olds 98, it was the first year they incorporated the smog controls. After the rebuild 12 years ago, nothing worked right. So this year I replaced the stock olds 307, with an olds 350 rocket (1972) with no computer controls and a Edelbrock 1406. So I wanted to be sure it wasn't running too lean or rich.Package comes with everything you need to install, except the gauge holder, I had several olds ones laying around. I already had a hole in the firewall for all of my other goodies, so that wasn't a problem, but may be for you. The lead to the sensor, and to the gauge is extra long, and is heat shrinked, and can be disconnected from the gauge as well as from the sensor.I had a problem getting the leads to connect to the gauge. It seemed the plastic housing, was too close to the pin connector, so I had to fight it for a little bit. The gauge also emits a high pitch whine, when powered on, but not a big deal as I am hard...

An ideal upgrade!
I have been using analog gauges and while they were very good in doing their job, I felt that I needed to upgrade the gauge(s) (there are two more gauges I will be giving a review towards) as I am re-doing my entire car. The gauges are easy to read, easy to understand, and they look great! I've been receiving a lot of positive feedback from others involved in the automotive customizing business. I'm glad I took the advice of my mechanics and a fellow speed nut (like me) and made the purchase.
