Tell me you can see exactly what I'm saying.... Your low rpm and high rpm pictures should be swapped around... they are totally opposite... look at the paths... (yeah on the closed mode, mine is more shut than urs, i think thats just the effect of that screw)


basically when the throttles are straight up it acts as a constrictor, with half the air taking a longer path... when they are laid out flat it blocks the top part off and the air has a more direct path...


What you're actually noticing is that ACIS is "stuck on" when your engine is running with the hood up, this is (I believe) due to trapped vacuum in the line which makes the actuator sticky... and when the motor is off the vacuum is free to escape.

Heres the thing... Apply 12v to ur Vacuum Solenoid Valve, notice it clicks open, If you unplug the hoses while your running the engine, you'll get a vacuum leak from one of the hoses and the motor will rev up... now with the motor running, unplug the 2 wire power plug from the VSV, notice your ACIS doesnt close, hit it with your multimeter, notice its on 0v... now unplug the hose going directly to the diaphragm... You'll hear a pop as the trapped vacuum in the line is released and the ACIS throttles will close... Get what I'm saying???? This was the whole reason behind the controller and the standalone vacuum routing i made... I incorporated a pressure release system in my setup so the throttles would close when they're supposed to be.
