AEM 30-0300

The 52mm (2-1/16”) AEM X-Series Universal Exhaust Gas Oxygen (UEGO) Gauge features a four digit central readout and

sweeping 24-color-coded LED display, providing immediate reference to the engine air fuel ratio (or lambda) in real-time.
The AEM gauge is ideal for all vehicles including carbureted applications and engine dynamometers. A 0-5V analog output
is included and can be used with data loggers or aftermarket ECUs including the AEM Infinity Engine Management
System (EMS). In addition, an AEMnet (CAN bus) and serial data stream are also available for logging or mixture control
purposes.
