AEM's UEGO Display Gauge includes a 0-5 Volt analog output that can be used with data-loggers or most aftermarket engine management systems, and includes an RS 232 serial data output port for data logging without an engine management system. These units display to 0.1 AFR and feature 24 color-coded LED display lights for immediate reference to engine AFR, and an integrated three-digit real-time display for AFR. The AEM UEGO Display Gauge is available with a silver or black bezel, and with a black or white face.

AEM's UEGO Display Gauge displays one channel only, so users wishing to display two channels simultaneously will need two gauges (V6 to V10 applications).
