Features

The FuelTech Flex Fuel Sensor allows the tuner to compensate for a change in ethanol content and also monitor the fuel temperature. This is all pre-determined and setup within the FTManager software giving the end user the ability to simply select the flex fuel sensor under inputs, determine the content of the fuel when it comes to tuning and input that data into the Flex Fuel wizard. From there the specific tables are populated based off the default ethanol content entered and compensations applied around the default percentage.

*Connector kit sold separately
The FuelTech Flex Fuel sensor has 3/8” push on/quick connect style fittings with a max flow of 1.76GPM or 400LPH.
