  • PROFLEX Commander E85 System

    What does the PROFLEX Commander do?

    The PROFLEX Commander™ delivers E85 performance to vehicles utilizing an ethanol sensor for proper calculation of fuel delivery (included with kit). The unit is bolt-on without the need for any modification or programming of the ECU. We currently have applications available for many cars, trucks, and motorcycles and are constantly expanding our application list. Our unit ensures your vehicle consistently maintains its stock or tuned air/fuel ratio no matter what fuel blend you use.


    E85 is a much higher performing fuel that can increase vehicle performance while running cooler and keeping your engine cleaner than running gasoline. Want proof that E85 increases vehicle horsepower? Check out our Dyno Data page. Whether you're looking to post better track times or just get more power and responsiveness out of your daily driver, with the PROFLEX Commander™ you can get race-grade fuel without the race-grade price right at the pump!

    PROFLEX Commander by Advanced Fuel Dynamics

    Is my vehicle safe?

    From dedicated track cars and sport bikes to daily drivers and cruisers, most modern stock vehicles do not require any additional upgrades to run E85 with the PROFLEX Commander™. Once installed, any mixture of gas and E85 can safely be run. If a vehicle is modified and cannot deliver enough fuel for full E85 operation, a lower mixture of ethanol can still be run to increase performance over gasoline. As little as 30% mixture of ethanol in gasoline is equivalent to around 100 octane. The PROFLEX Commander™ is compatible with all major vehicle manufacturers and includes a 1-year limited warranty. If you have any special concerns, just give us a call at 866-902-FUEL!
