Black box???
Hello everyone!! I know you guys are going say this thread is somewhere on the forum but i just cant find it. The question is....I have a little black box on the back of my h22 motor. It has a piece broken on it. My friend says it can be eliminated. But i dont know if i totally trust that. And if so what should i do to secure any air leaks?

Re: Black box???
Ok what do I do exactly to replace this box? Do I get those little plastic caps to cover up the holes?? And by removing this box what exactly happens??

Re: Black box???
just got my first h22a1 and f22a a week and a half ago so im gonna give this a try
either get a new box, go to a junkyard and get one for a steal, or delete it. the box controls the iabs which are basically four little throttle plates inside your intake manifold. the manifold has eight holes leading to the runners. four of them are open at all times the other four have a plate that looks like a throttle plate in them. what the box does is tells these plate to open at a certain time-higher rpm/intake vacuum. im not sure which one it is. i have seen people say either or. maybe someone with their head on straight can better explain. all i know is my f22a with the iabs has an electrical connector on the black vacuum box so im guessing the ecu has to know something about the iabs
the purpose of the plates is to give you more low end torque and then when at higher rpms the plates open allowing room for more air to travel into the lower manifold runners.
removing the box and capping everything off will result in the plates staying closed. there is a spring on the drivers side of the manifold that holds them closed. im not positive on this but the spring is pretty strong. they may open a little at high rpms due to high vacuum but there is no way they will open enough
removing the box and running a hose from the flying saucer looking thing back to the upper intake manifold will allow the plates to open when there is enough vacuum-higher rpm situation. this is ideal for a daily driver if you wanna go the cheap route and dont replace the box the proper way.
