Q & A


The AEM wideband fail safe gauge provides the ability to accuratley tune your air/fuel ratio gauge while protecting your engine by monitoring the air/fuel ratio curves and activating a user defined failsafe if the car is running lean. The wideband failsafe is a UEGO controller with an internal boost sensor (up to 29PSI), an internal data logger and a full colour OLED display. This gauge is a must have for all tuned performance engines as it can trigger a user defined output function that can save an engine from catastrophic damage. 

The gauges failsafe is completely user definable from making the gauges flash to using the output to trigger a check engine light in order to cut boost, retard timing or even switch to a safety map using a standalone engine management system.

The gauge comes with a black and silver bezel and 6 interchangable faceplates:

  • 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
