FLEX FUEL WIDEBAND FAILSAFE GAUGE TECHNICAL FEATURES:
FLEX FUEL WIDEBAND FAILSAFE GAUGE INSTALLATION FEATURES:
WIDEBAND FAILSAFE GAUGE FACEPLATE STYLES:
The Flex Fuel Wideband FAILSAFE Gauge (PN 30-4910 w/o Ethanol Content Sensor) displays Air/Fuel Ratio, Boost/Vacuum and Ethanol Content, and can actively protect your engine from damage if it runs lean or excessively rich. IF YOU NEED AN ETHANOL CONTENT SENSOR WITH YOUR FLEX FUEL WIDEBAND FAILSAFE GAUGE, PLEASE CLICK ON PN 30-4911.
The 52mm (2-1/16”) Flex Fuel 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 29 PSI. It is available with or without an ethanol content sensor for users who may already have one (PN 30-4910 no sensor, PN 30-4911 includes sensor). An internal data logger is included to capture approximately 2.5 hours of data on a loop, and includes two analog outputs for logging AFR, Boost/Vacuum and Flex Fuel content, and any triggered alarms. The gauge also includes a low side output for triggering a failsafe strategy in the event AFR falls outside of the operating window (see example strategies, below).
This product is a must have for all tuned performance engines who use Ethanol-based fuels like E85, either forced induction or naturally aspirated. Any high performance vehicle owners who want an accurate AFR tuning tool with integrated logging and the ability save an engine from catastrophic failure will want the Flex Fuel Wideband FAILSAFE device.
WHAT IT DOES
After the engine is tuned and a safe operating window of AFR is established, the Flex Fuel Wideband FAILSAFE Gauge continuously monitors AFR/Lambda and Boost/Vacuum to make sure that AFRs do not fall out of a user defined operating window. If it 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).
VIBRANT Organic LED DISPLAY
AEM’s Flex Fuel Wideband FAILSAFE Gauge’s feature a vibrant Organic LED (OLED) center readout that can be user-programmed to display AFR/Lambda and Ethanol Content, Boost/Vacuum and Ethanol Content, or a single input of either AFR/Lambda or Boost/Vacuum. The 24 sweeping outer LED ‘needles’ can be programmed to display AFR or Boost/Vacuum, and corresponding faceplates are included for matching the inputs to the proper display layout (see Specs tab or Images tab for faceplates). A silver bezel is also included to further customize the look of the gauge face.
EASY TO SET UP
The gauge’s intuitive software makes set up and configuring the low side output a snap. Setting AFR boundary limits, creating a user-adjustable time delay strategy to prevent false alarms, customizing the gauge lighting to flash and alert the driver if an alarm is triggered and configuring the LED displays are all performed using the software via a USB connection.
ON-BOARD DATA LOGGER
The Flex Fuel Wideband FAILSAFE Gauge’s on-board data logger stores approximately 2.5 hours of data (20 Hz per parameter) of AFR, Boost/Vacuum, Flex Fuel content and Alarm events. Data logs can be downloaded for viewing in FREE AEMdata software, which includes video encoding to overlay data onto your videos. Users with AEMnet-equipped (CAN bus) devices can daisy chain the Flex Fuel Wideband FAILSAFE gauge using the AEMnet connection (adapter sold separately). Non AEMnet-equipped devices can communicate with the gauge using the CAN 2.0B spec protocol. An analog output for O2 feedback is also provided for 3rd party engine management systems, or logging with a stand-alone 3rd party data logger.
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.
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.
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.
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.
