I was using our Turbo Calculator and our E85 Calculator to help an old friend of mine confirm his choices for performance parts for his buildup. He is building an 800 horsepower 3000GT VR4 using a Borg Warner S372 single turbo, dual 38mm wastegates, 272* cams and an E85 Conversion using Injector Clinic's FIC2150's ...
During our conversation we ran into an amazing new engine management system by ProEFI. This system uses a GM style Alcohol concentration sensor mounted in the gas tank to linearly extrapolate between two tuned maps for your vehicle... the first map is a 100% gasoline fuel, timing and boost map, and the second map is a 100% Alcohol/Ethanol fuel, timing, and boost map...
Once those two maps have been dynotunes, the ProEFI system automatically figures out how close you are to either map based on what fuel you are carrying in your tank... and delivers the right amount of boost and power for that octane level.
If you're the kind of person that likes safeguards in your system, the system also comes with built in knock-retard in case something isn't quite right AS WELL AS a fuel pressure safety system that can detect a weak or clogged fuel delivery system, can detect a drop in fuel pressure and will put your car into a conservative low-boost tune accordingly to prevent catastrophic failure and save the motor.
I'm very impressed by this system because you can tell it was designed by the racers, for the racers as it covers power and safety which is what we want...
