yeah ive been soaking up information about the iacv and how it works and how we could fool the ecu .. i dont think its gonna be hard in the end its just a matter of research.... heres what i got so far if it helps anyone.

Idle Speed Control (ISC) Inductor with 58mH inductance and ~ 15 ohm DCR
Uses PWM Pulse Width Modulation to open and close.
Idling is the state during which the accelerator pedal is released with the engine running. With conventional engines, the idle speed was adjusted slightly on the high side so that the engine will not knock. However, the engine's condition changes over the years, therefore the idle speed becomes unstable. If the idle speed is unstable, unpleasant vibrations or engine breakdown when started may occur, or fuel economy may drop. To eliminate such problems, ISC has been introduced to optimize the idle speed. In this method, an air bypass passage is provided in parallel with the throttle valve, and opening degree of the ISCV (idle speed control valve) attached to this passage is adjusted by the ECU. This causes the quantity of bypass air to change, thereby controlling the idle speed.
Idle speed control valve (ISCV) (Linear solenoid valve)
A solenoid valve attached to the throttle body. Quantity of intake air is adjusted as the opening degree of this valve is controlled.
