AEM's highly popular Analog-Style Wideband O2 air/fuel ratio UEGO gauge features a high-speed electric stepper motor for lightning-fast needle movement and a full 320 degrees of viewing resolution to detect even a .5 degree of change in AFR. Seven backlit colors allow you to match the lighting to most factory gauge clusters. A 52mm (2-1/16") gauge housing ensures that it will fit in most gauge pods and can be remotely mounted virtually anywhere. All AEM gauges feature a 0-5v analog output for use with data loggers and almost any engine management system.
The Analog-Style Wideband O2 air/fuel ratio UEGO gauge is a must if you want to maximize your engine's power and safety. When tuning an engine, accurate air/fuel ratio data is critical because running with too rich of an AFR can cause a loss of power, and running a lean AFR can result in serious engine damage. AEM's Analog-Style Wideband AFR UEGO gauge can quickly alert you to even a .1 change in air/fuel ratio and provide enough time to shut down an engine before damage occurs.
The Bosch UEGO sensor gives the controller its speed and accuracy. It is laboratory calibrated at the factory and NEVER requires free-air calibration when used with AEM wideband air/fuel controllers.
