AEM Air Fuel Ratio Guage
The 52mm AEM Air Fuel Ratio Guage features a digital 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 user-selectable 0-5V analog output is included and can be used with data loggers as well as an input to most programmable ECU's.
A serial data stream is also integrated for air fuel (or lambda) ratio output to a RS-232 com port.
