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.


The software's intuitive Gauge Configuration tool makes setting up the faceplate configuration a snap. The software also simplifies set up of the AFR safe operation window and alarm trigger (see Capability tab).

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
  • 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

WIDEBAND FAILSAFE GAUGE INSTALLATION FEATURES:

  • AEMnet compatible (CAN 2.0)
  • Differential AFR analog output
  • Differential boost analog output
  • Configurable RPM input for logging
  • One low-side driver output (Ground with 1.5 amp max draw)
  • Positive-lock connectors
  • Tunable PC-based software with USB connectivity
  • Time based reset for outputs

WIDEBAND FAILSAFE GAUGE FACEPLATE STYLES:

  • Kit comes with 6 different faceplates and black and silver bezels.
  • Black Vacuum only in sweeping LEDs
  • Black and White AFR in sweeping LEDs
  • Black and White Vacuum/Boost in sweeping LEDs
  • Black Lambda in sweeping LEDs

After the engine is tuned and a safe operating window of AFR is established, the Wideband FAILSAFE Gauge continually monitors AFR and boost or vacuum to make sure that AFR does not fall out of the defined operating window at a given boost or vacuum level. If the Wideband Failsafe detects an out of range AFR reading, the gauge triggers a low side output (ground signal with a 1.5 amp draw max) that can save your engine from catastrophic damage (see example strategies, below).

Use the gauge’s intuitive software to configure the low side output, create a user-adjustable time delay strategy to prevent false alarms, and customize the gauge lighting to flash and alert the driver if an alarm is triggered.


Use the Wideband Failsafe gauge's intuitive software to establish a safe AFR operating window, configure the low side output to trigger a failsafe strategy and set a time delay strategy to prevent false alarms


The Wideband Failsafe Gauge contains an on-board data logger for logging over three hours of data recording (20 Hz per parameter) of AFR, RPM, boost, alarm, and others. Data logs can be downloaded for viewing in AEMdata software.

Additionally, the Wideband Failsafe Gauge is an ideal engine tuning tool. The highly accurate Bosch AFR wideband sensor is maintenance free and never requires free-air calibration, enabling you to fine tune AFR from an AEM programmable engine management system, any other programmable EMS or piggyback programmer. For carbureted applications, it can tell you when it’s time to swap carb(s), change jets or simply modify fuel pressure.

EXAMPLE ENGINE PROTECTION STRATEGIES
NATURALLY ASPIRATED, TURBOCHARGED OR SUPERCHARGED WITH STAND ALONE EMS OR PIGGYBACK CONTROLLER: Can use the low side output to cut revs, retard timing, trigger a separate fuel or ignition map and activate an ancillary warning light. Users with turbos can also trigger the device to cut boost (may require separate solenoid). The aforementioned strategies are provided as an example. Available failsafe strategies will ultimately be dependent on the capability of the EMS or piggyback engine controller.
