Ever wonder why Advanced Fuel Dynamics was founded? Watch this short video of founder Ryan Truax explaining why he started the company and created the PROFLEX Commander product line. The PROFLEX Commander solves the problem of running E85 in your car when the E85 you get from the pump is wildly inconsistent in ethanol content. It's like a standalone for flex fuel, allowing you to run E85, gas, or any blend you want seamlessly without requiring any user input or tuning upon installation. The PROFLEX Commander ensures your vehicle is safely making the extra power it should no matter the blend of ethanol. Use the smartphone app to view your ethanol content in real-time, too.
