More Info:
AEM Wideband Failsafe gauges provide the ability to accurately tune the air/fuel ratio, while actively protecting your engine by constantly monitoring air/fuel ratio curves and activating a user-defined failsafe strategy if it runs lean. They can also be used as universal exhaust gas oxygen (UEGO) controllers with an internal boost sensor.
This gauge features an internal data logger, a full color Organic Light Emitting Diode (OLED) display, and the technology to activate a failsafe strategy in the event that the air/fuel ratio falls outside of a user-defined operating window. When this occurs, the user-defined output function that’s activated, can save an engine from catastrophic damage. They are a must-have for all tuned performance engines, whether forced induction or naturally aspirated, fuel injected or carbureted.
These gauges also include six different faceplates and black and silver bezels.
