Idle air control valve IACV, idle speed control valve ISCV from 3sgte engine (MR2 and Celica)

My "new" 70mm throttle-body (from a Lincoln LS) is lightweight, progressive, and simple in design... it has no through-passages or air bypass valves. When bolted to my redesigned intake manifold, I needed to have computer-controlled idle adjustment for cold startup. I am still on the stock 3sgte ecu for this year, so I made an adapter plate for my TPS (throttle position sensor) and a semi-remote mounting point for my IACV. Without the valve I had to hold my foot on the gas pedal a little during cold startup. Once warm, the car idled fine at 800 RPM. So, I needed to adjust the range of my IACV, and get it to close as much as possible, or my idle might be too high when warm. Now the valve will open on cold startup to give me a higher idle. I may re-adjust my idle stop screw and my TPS in the future to reduce my idle RPM's and give the IACV more control.
