    The Proflex Commander system by Advance Fuel Dynamics is supposed to let you run E-85 in your late model engines. It advertises that it allows you to switch between E-85 and straight gas seamlessly. The benefits are better performance than premium, cooler running and more tolerance to powers adders. However, since E-85 does not have as much energy yield as gas you will burn more per gallon, but it is cheaper. Saw it on Stacy David's Gears show. Just curious if anyone is using it on their hemi.

    Burn more but it's cheaper. Sounds like a wash. That said........let me say this. THANK YOU THANK YOU THANK YOU for asking about a product and not only TELLING US what it is, BUT ALSO posting a video. Most of these cats just ask if we've heard of something with NO explanation, NO pictures, NO link, NO nuthin. YOU however broke the mold and I for one thank you!

    It looks and sounds purdy interestin IF you wanna run E85. The only reason I would run it would be to get away with more compression than pump gas could handle and THEREFORE that would render it for me useless, because I'd have no reason to switch back and forth. Maybe I'm "not seein it" but I don't really see a reason to switch back and forth. Well........I can think of one. If you had nitrous. That's kinda a "temporary" power adder. A blower, turbo or high static compression ratio is a much more permanent power adder and "to me" you would not want to switch back to 100% gas......but maybe I'm missin somethin.

    I mean....it just "seems like" either you want E85 or not. Help me out here.

      You have to remember that the alcohol is corrosive to the metal parts that is why flex fuel vehicles have all stainless lines, I think it's the alcohol absorbs moisture and the water is corrosive to the metal alcohol will eat the rubber if it's not the right kind.

        Right it's not the alcohol itself, but the moisture it holds that corrodes. I just farted. That corrodes too.

          I saw this used on one of the car shows I watch, and they said the system senses what fuel is in the line and adjusts for it.
          Which also required a bigger better fuel pump and oversized injectors for when running the E85.
          Didn't really look worth it to me, but it was cool to know.

          Me either. My fast 2.0 can switch back and forth , but with 10.3 comp. , I don't see any need of "rusting the new tank ".

          It's a good thing it can "sense" the blend. Blender pumps around here are not even close to 85%.

          I've run E85 in several of my cars and trucks....mostly on longer trips. Fuel economy was about the same as gas and it's usually 80 cents per gallon cheaper.

          Haven't used it lately since it's no longer available in my town.

          I've been writing E85 tunes for over 10years and the fuel's +100oct awesome especially if your Boosted. BUT E85 requires 20-30% more fuel than Gas.

          The big issue I have with kits like these is that many stock injectors, regardless of make or model, just don't have an extra 30% capacity at WOT to deliver the added fuel E85 demands.

          To be safe, at the VERY LEAST, WOT A/F needs to be monitored with a wideband and injector duty cycle measured. You most likely will have to add larger injectors.

          Also to maximize performance at WOT with E85, timing should be adjusted as well. A DiabloSport tool can adjust fuel and timing at WOT and also flash a Custom tune if larger injectors are needed.

          An alternative to this kit is a new tune via HP Tuners. For many 2013 and newer Chryslers, HPT has unlocked and CAN ADD the factory Flex Fuel algorithmes to your NON FLEX FUEL PCM. This is by far the BEST means to add E85, since there are A LOT of tables that the Flex Fuel PCM modifies AS WELL AS it will automatically dial in the proper ignition timing for all conditions for E0-E85(start, idle, cruise WOT)
