AEM Monitoring System





AEM 6-in-1 Gauge-Type UEGO Wideband Controller

AEM’s Wideband that combines a gauge, a single-channel analog output, and a Bosch O2 sensor in one unit!

Now includes black and silver bezels and black and white faces! One part number, 6 color combinations!

This unit has both an LED readout and a sweeping LED series that changes colors as the air-to-fuel ratio progresses from rich to lean. The 52mm (2-1/16”) sizing works with most gauge pods and makes for a simple, clean installation.

No laptop or EMS required for monitoring.

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.
