hi pert,
i am personally using FICD on my sr20de. coz my throttle sensor for aircond ko d, hard to find a replacement.
for the FICD, the vacum intake has a screw, which means you can adjust the amount of air for the vacum hose to enter your intake manifold. so if you are using super highcam, you just need to adjust the air intake screw on your FICD.
the FICD comes in 2 types of switch which is activated once your aircond is on. 1 type trigger the FICD when then electric current is on, another type is vice versa. I think any aircon workshop can figure it out easily
