First of all, all E85 is not equal. When you go to the pump your E85 is going to be somewhere between 51% and 83% ethanol. That’s the federal standard. To run E85 safely and get the most power the fuel volume at the injector (fuel load) needs to be precisely indexed to the ethanol percentage. If it is not, you can either run dangerously lean and burn a piston or you can run rich and wash your cylinder walls which will cause piston ring failure and cylinder wall scoring. Not good.
An “E85 tune” is a dinosaur in the industry. An E85 tune is good for one thing; 85% ethanol, which as we’ve explained, you will never get at the pump. Essentially, an E85 tune is only for cars that run barrel grade race fuel that is guaranteed to be exactly 85% ethanol. If you want to go to the pump for your E85, or run gas sometimes an E85 tune is a terrible idea and will definitely (DEFINITELY!) damage your engine. Our patented ProFlex technology was developed specifically to solve the problem of the engine damage and reduced life expectancy caused by E85 tunes.
There are also “wide band” systems that work off of your oxygen sensor data to try to correct the rich/lean condition caused by differences in fuel content. The time it takes to adjust to changes in fuel content is called latency. For comparison, a wide band or “flex tune” can have latency for as much as hundreds of miles. The Commander works in real time and has zero latency. In short, wide band systems are painfully slow, nearly always incorrect and will definitely cause your engine to fail prematurely. Again, we are not saying wide band doesn’t work, but it is a terribly slow and inaccurate way to handle flex fuel and with the ProFlex Commander available there is no reason to settle for something that works half as well and generally costs more.
WARNING: If you ever see a system that requires you to measure your fuel content or watch your injector duty cycle, run the other way. There is no reason you should have to work to run E85. Mathematically derived duty cycle is a mythical beast using fuzzy math. It is a smoke and mirrors way to convince you to buy an inferior management system.
Your engine performance and life expectancy depend on you making good decisions when you choose a flex fuel solution. A new engine is a lot more expensive and painful than getting the right solution now. AFD customers have never reported any engine damage from using our system in our entire history and we are not going to start with yours!
The ProFlex™ Commander is the most sophisticated and accurate way to run E85 and it is patented. We developed the Commander to do all of the heavy lifting for you.
The key to injector performance is the most complete atomization of the fuel possible while delivering precisely measured fuel volume. Our patented Digital Injector Management™ (DIM™) is incredibly fast and accurate, meaning we can control your injectors much more precisely than your ECU/PCM, which uses slower analogue duty cycle signals. DIM delivers fuel loads more accurately than any other system, with the ability to digitally manipulate both injector pulse duration and speed allowing for better atomization and improving performance. This is why the Commander typically increases horsepower even when the vehicle is running on gasoline. In fact, by eliminating the obsolete analogue duty cycle control from the equation, the Commander can actually deliver more fuel at any given load than any other injector management system including your factory ECU allowing your injectors to supply E85 exactly as needed. Even without E85 the Commander is a vast improvement over your factory computer in terms of injector control and fuel management.
Our BlendSense™ technology measures content in real time with a 30 microsecond refresh rate and zero latency, meaning the system is always 100% correct no matter what fuel you are running and is seamlessly compatible with gas tunes and power adders.
Simply put, the Commander does exactly what it is supposed to do in real time with no monitoring, flashing, upgrading or measuring. It is the only flex fuel system like it in the world. There is simply no more accurate and reliable way to maximize power and engine safety than the ProFlex Commander. And the Commander is made in the USA.
