AEM FlexFuel Fail-Safe Wideband (with FlexFuel Sensor)

AEM Electronics

AEM-30-4911

The Flex Fuel Wideband FAILSAFE Gauge (PN 30-4911 w/ 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 HAVE A FLEX FUEL SENSOR, PLEASE CLICK ON PN 30-4910.

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 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.
