AEM Wideband Failsafe Gauge

  • $325.79


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.

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.

The gauge’s failsafe strategy is completely user definable, from something as simple as making the gauge flash to using the ground output to trigger a check engine light, to cut boost, retard timing, or even switch to a safety map using a standalone engine management system.

The Wideband Failsafe Gauge’s software simplifies the interface set up. Choose displayed parameters (AFR, boost or vacuum) on the center OLED screen and bar graph, set the alarm flash mode and adjust the gauge’s lighting for a custom look, then install the correct faceplate to match your configuration (6 faceplates to choose from).
