I think I am going to bang my head against a wall form all the bad info in this thread.
1) The cyclone intake is normally OPEN as in both runners.
2) It closes off the secondary runner by vaccum, not boost.
3) The vaccum canister is controlled by a BCS-style solenoid that traps the vaccum to keep the butterfly valve closed. Once the JDM ecu decides to open it, it opens the valve and boost hits the actuator and opens the secondary runners.
4) In order to get it to work right, you would need a solenoid that closes at any non vaccum signal to trap vaccum in the canister, and a way of opening the solenoid at a specific boost.
5) This has been gone over hundreds of times:
