AEM's Wideband UEGO Controller is also available in a gauge that includes a single-channel analog output with a Bosch O2 sensor in one unit! The controller also features an LED readout and sweeping LED "needle" that changes colors as AFR fluctuates from rich to lean. The 52mm (2-1/16") gauge housing fits in most gauge pods and can be remotely mounted virtually anywhere.

If you’re adding modifications to your vehicle, and are boosting under a whim how can you know how your engine is running? If you’re running to lean you will cause premature engine damage and you’re not gonna have a good time. Invest wisely and get a wideband gauge. This particular example from AEM features an easy to read 52mm interface. Comes with a Bosch sensor, and reveals AFR’s in real time.
