Flex Fuel / E85 Ethanol Sensor Kit – Connector & Aeroflow 6AN Fittings
Genuine GM / Continental Flex Fuel Sensor Kit
A complete solution for adding Flex Fuel / E85 ethanol-content monitoring to a compatible engine-management system.
The sensor measures the ethanol concentration in the fuel, allowing a compatible ECU to adjust the calibration according to the actual ethanol content rather than relying on a fixed assumed E85 percentage. Actual ethanol concentration can vary, which is one of the main reasons for using a flex-fuel sensor.
KIT INCLUDES
- Genuine GM / Continental Flex Fuel Sensor
- Electrical sensor connector
- Connector terminals / pins
- Aeroflow 6AN fittings
- Complete sensor package ready for integration into a compatible fuel system
ECU COMPATIBILITY
Suitable for compatible standalone and programmable engine-management systems with flex-fuel functionality.
Examples can include systems from:
Haltech | Link | MaxxECU
Compatibility and ECU configuration should always be confirmed before ordering.
IMPORTANT
Professional installation and ECU calibration are recommended.
Fuel-system components, hose and fittings must be compatible with the fuel being used. The fuel system must be depressurized before installation, and all quick connectors must be fully secured and leak-checked before operation.
Worldwide shipping available.
