I have an supercharged 02 Trans Am that is speed density tuned with a 2 bar MAP. I would like to be able to use the 02 sensors in closed loop with the tune. How is this accomplished? Do you activate the 02 by enabling them by setting the closed loop temp enable to around 92F? What tells the 02 to turn off when in full throttle? Can you have an active maf with a 2 bar MAP set-up or is this only a speed density parameter?
