Ohhhhhhhhhhh. OK.

I thought closed-loop was when the computer ran pre-determined fuel maps and that open-loop was where the ecu took feedback.

I guess my mom's car is in open-loop mode then cuz the O2 sensor is busted.

So... our cars run open-loop under anything but light load, correct? Does the ECU ever adjust its fuel maps for open-loop at all? Or do they permanently stay the same as they came from the factory?

 

J-Rat if I were you I would go with 1600's in the secondaries, and 720's in the primaries. I have seen many people with this setup, running succesfully on alot of Turbo 2s

 

That's over 600hp worth of flow capacity, which is total overkill for his needs.
