AEM Universal Wideband Failsafe Gauge (Air/Fuel Ratios and Manifold Pressure)

$320.00

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 product 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.

The 52mm (2-1/16”) Wideband FAILSAFE Gauge includes a Bosch 4.2LSU AFR wideband sensor for monitoring and feedback of AFR and an on-board boost sensor to read vacuum or boost pressures up to 30 PSIG. Both boost and AFR can be displayed in real time on the gauge’s face using the full color OLED screen and 24 three-color sweeping LEDs. The gauge includes a low side output for triggering a failsafe strategy in the event AFR falls outside of the operating window (see example strategies, below), and an RPM input to log RPM for tuning purposes.
