AEM Wideband UEGO Gauge – Digital Air/Fuel

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.
