ProFlex DX Adaptive Flex Fuel System

The Advanced Fuel Dynamics ProFlex DX is an adaptive flex fuel system designed for the 2018-2023 Mustang GT and Mach 1 with the 5.0L Coyote motor. This system allows you to run E85 fuel for increased power and cooler engine temperatures, with a true plug-and-play installation that requires no tuning. The patented BlendSense™ technology provides real-time adjustments with a 30-millisecond refresh rate, allowing seamless switching between gasoline, E85, or any mixture of the two.

Developed and tested over 2,000 miles of street, track, and dyno use, this system is the only real-time flex fuel option on the market for these specific vehicles. It features digital injector management for enhanced performance on both gas and E85, and is compatible with most power adders and bolt-ons. The ProFlex Connect app displays real-time ethanol content on your smartphone, and Cold Start Plus™ technology improves cold-weather starting.
