AEM Universal Wideband Failsafe Gauge (AFR/PSI)

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.

Features:

  • Bosch Wideband UEGO sensor and weld-in bung included
  • On-Board 3+ hour Datalogging capability at 20hz per parameter
  • Intuitive set up software (PC based with USB connectivity)
  • Interchangeable faceplates and bezels
  • No free air calibration required”ever
  • Data analysis using AEMdata software
  • AEMnet compatible
  • Standard 52mm gauge size

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 internal data 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.

WIDEBAND FAILSAFE GAUGE TECHNICAL FEATURES:

  • Displays both boost or vacuum and AFR or Lambda simultaneously on the same gauge
  • Internal boost sensor
  • Bosch Wideband UEGO sensor and weld-in bung included
  • On-Board 3+ hour Datalogging capability at 20hz per parameter (AFR/Lambda, Boost/Vacuum and RPM**)
  • Full color Organic Light Emitting Diode (OLED) Display in center, user selectable feature (boost/vacuum or AFR)
  • 24 three-color sweeping LEDs, user selectable feature (boost/vacuum or AFR)
  • Intuitive set up software
  • Dimmer input included
  • Interchangeable faceplates and bezels (see options, below)
  • No free air calibration requiredever
  • Data analysis using AEMdata software
