AEM's Wideband Failsafe Gauge provides the ability to accurately tune AFR, while actively protecting your engine by constantly monitoring AFR curves and activating a user-defined failsafe strategy if it runs lean.
The Wideband Failsafe Gauge is a Universal Exhaust Gas Oxygen (UEGO—“you-way-go”) controller with an internal boost sensor, an internal data logger and a full color Organic Light Emitting Diode (OLED) display. It includes technology to activate a failsafe strategy in the event AFR falls outside of a user-defined operating window. If the AFR falls outside of the set operating window, the Wideband FAILSAFE Gauge triggers a user defined output function that can save an engine from catastrophic damage.
This gauge is a must have for all tuned performance engines, either forced induction or naturally aspirated, fuel injected or carbureted. Any high performance vehicle owners who want a highly accurate AFR tuning tool with logging and a protection strategy that can save an engine from catastrophic failure will want this Failsafe device.
Since the Wideband Failsafe Gauge is a wideband AFR controller with an internal boost sensor (up to 29 PSIg), it is able to display AFR and either boost or vacuum in real time on a vibrant Organic LED screen. It also includes an on board data logger that records AFR, RPM and boost/vacuum and can be downloaded and viewed in AEMdata analysis software. The gauge includes a low side output for triggering a failsafe strategy in the event AFR falls outside of the operating window, and an RPM input to log RPM for tuning purposes.
The gauge’s failsafe strategy is completely user definable, from something as simple as making the gauge flash to using the ground output to trigger a check engine light, to cut boost, retard timing, or even switch to a safety map using a standalone engine management system.
The Wideband Failsafe Gauge’s software simplifies the interface set up. Choose displayed parameters (AFR, boost or vacuum) on the center OLED screen and bar graph, set the alarm flash mode and adjust the gauge’s lighting for a custom look, then install the correct faceplate to match your configuration (6 faceplates to choose from).
