AEM Wideband Digital Air/Fuel UEGO Gauge (30-4110NS)

An AEM Wideband UEGO Gauge is a wideband sensor controller that monitors air to fuel ratios (AFR) as you tune up your car. The goal of using the device is to prevent a lean fuel mixture that may damage the vehicle’s engine and prevent a rich fuel mixture that decreases performance.

To improve AFR accuracy and control, AEM combines its single-channel wideband UEGO controller and gauge display into a single unit that features a user-friendly interface. 
The AEM Wideband UEGO Gauge is an AFR controller and a gauge comprised in one unit. 

Benefits of the Gauge

Using accurate AFR data is essential for tuning up an engine for two reasons. When a vehicle runs too rich as a result of having low air to fuel ratios, it can result in a loss of driving power, and running too lean due to high air to fuel ratios can seriously damage the engine.

It’s essential to use the gauge during tune up, allowing you to monitor AFR and alter your tuning parameters in order to optimize them to deliver the highest levels of power and efficiency.

Free-Air Calibration

Some manufacturers of AFR measurement devices require O2 sensors in the equipment to have free-air calibration performed to calibrate the sensors. This isn’t necessary when you use the AEM Wideband UEGO Gauge, which contains Bosch 4.9 LSU sensors. Individually laboratory-calibrated, this sensor from Bosch requires no free-air calibration.

Tune With Confidence

If you’re tuning up a vehicle to redefine its performance, the last thing you want is to find that the tune up job doesn’t deliver the performance you desire. Using an AEM Wideband UEGO gauge is one way to keep this from happening.
