Does any one know if the profec B is open or closed loop?
thanks

Not exactly sure what you mean....are you talking about the electronics that are controlling the valve?

What I do know is that it is an awesome boost controller.

closed loop is a lot more accurate, but you say its pretty good ay?

closed loop means that you progam in x psi of boost, the sensor looks at existign boost and and compares it to the ideal x, then it does what it needs to to get the real close to the ideal, it does this many times a second i belive..... that is what a closed loop system would do, but i dont know if profec b II is one.
