ProFlex Commander is a plug-and-play (full bolt on) E85 flex fuel system that allows you to immediately start making more power by running E85. No tuning required. You can think of it like an adaptive E85 tune in a box, ensuring you maximize your vehicle’s power and safely no matter what fuel blend you are running.
A flex fuel system allows a vehicle to run E85, gas, or any blend of ethanol and gas seamlessly without any user input required. A performance flex fuel system like the ProFlex Commander does this in real-time while maximizing power gains for the vehicle no matter the fuel blend.
An E85 tune is only set for a static ethanol content, and since pump E85 varies widely in ethanol content, the tune will never be correct using pump E85. Also, once your vehicle is tuned for E85 you can no longer run gasoline unless you have the ability to switch maps, which itself is a huge hassle because you have to drain your tank (which is actually not possible to fully do) and then switch maps using an OBDII port hand-held flashing device. With an E85 tune you can be limited geographically to staying near E85 pumps. With the ProFlex Commander you get all the benefits of an E85 tune without any of the limitations. Run anything you want whenever you want and pump variation is handled automatically!
If you already have a pump gas tune you don’t need to change a thing. The ProFlex Commander will work seamlessly with your existing tune or if your ECU is still stock.
The ProFlex Commander is a plug-and-play system, so there is no tuning required. You can think of the system as an automatic, dynamic tune, changing in real-time depending on how much ethanol you are running.
We don’t see measurable gains past 80% ethanol, especially on n/a (naturally aspirate) applications. Running our system with a full tank of E85 will yield the best results.
We do R&D on each and every application we sell systems for and most stock vehicles do not need bigger injectors or fuel pumps to run full E85. If your vehicle requires changes to the fuel system, it will be noted on the product page. Also, depending on your vehicle’s setup (specifically if you are running an aftermarket supercharger) you may be limited to how high a blend of ethanol you can safely run. Please contact us
and we’ll be happy to talk with you about your specific application and setup.
No, all vehicles since the late 1980s on come with ethanol-compliant fuel lines from the factory. If your ProFlex Commander system includes a fuel line it is for the fuel sensor installation to ensure that the line doesn’t get crimped and inhibit fuel flow.
Ethanol ignites at a much higher temperature than gasoline, so you may see longer crank times to start your car, especially in colder weather. This is totally normal for all vehicles running ethanol.
Yes, our system will work great with the mods you already have! Other mods are great because the more power your car is making before you install our system the more power you will make after on E85.
Yes, this is one of the best mods you can do as you will feel power gains across your vehicle’s entire rev range. Unlike other mods which just give you a little bump at a high rpm, running E85 with the ProFlex Commander gives you more HP and TQ along the whole curve. Check out our dyno data for see for yourself!
