Wideband Air/Fuel and Boost in One Gauge!

WHAT IT DOES
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.
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.
WHAT IT INCLUDES
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 29 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 (example strategies below), and an RPM input to log RPM for tuning purposes.
