Someone probably has the frequency of the idle air control valve if that's what your talking about. Troll the MS3efi forum instead of KA-t read stuff that doesn't even directly apply to your engine. You will learn a lot. You could also just use the jeep? I think it was idle air control valve that diyautotune sells with the adapter block thing. We did that on a celica supra and it worked fine. It sits external to the engine with a hose in front of the butterfly and one behind. Then we blocked the idle passage on the factory throttle body with epoxy so it wouldn't leak. It was on a 2JZ VVTI swap thing.

If it is a track only car you can easily cheat and just crack the throttle body stop or fab one since you won't car about the warm up or a slightly higher idle anyway.

Having Megasquirted my KA with a friend I can tell you that the IACV's on a KA are a pain. What are your exact goals for the MS ecu? Is this a daily or track only? Fuel only? Spark Timing? Coil on Plug? Just to run?

I'll help you as best I can from what I remember.

I can tell you that for the KA I found it easiest to pull off the intake manifold and remove the accessory valve and the idle air control valve to replace them with a GM stepper type, which I got running, but eventually just removed for a throttle stop. But this will depend on your car.
