Who REALLY knows?

Grabbed up some Block off plates put those all on.

Heres my question the hard vac lines that have the solenoids on them do those need to go back on? and also it seems there are alot of other parts that dont seem like I need ot put them on?

There is a pressure sensor is connected to the Air control Valve but I eliminated that so of course I cant put that back on.....

Air bypass valve and check valve.....
Air bypass Solenoid Valve I mean is there really anything that NEEDS to go back on?

What do you do about the sensors that you plug in from the harness too btw? Doesnt the ecu show a check engine light all the time??? Whats the way around this aspect of things?

This is a picture of the hard lines Im talking about do I need these at all
Of course I need the pulsation dampner and pressure regulator and see hoses run to them but cant I just run hoses straight to them without having to use the WHOLE thing? this way it will eliminate some crap in the bay???
???

There are writeups on emissions removal, look at them.

I would answer your question here, but it completely depends on what functionality you intend to keep.

I used Kevins write up on Emissions removal. But what Im asking is not covered. I dont really intend on keeping any emissions items that are not needed. I really want to remove everything I dont need. The only thing that crosses over into emissions dept that I am keeping is my OMP. I dont want to have to premix.... other than that if the car can run without it I want it gone.

Maybe I will just continue to put things together and figure it all out as I go, help before hand would have been a lot easier though...

You can get rid of the whole vacuum rack and run lines straight to the fuel rails.

ok awesome so there is nothing else Im not seeing or thinking of that is running off that rack perfect!
EXACTLY what I was looking for!

and what about in the way of sensor etc that plug into the engine harness if those items arent there wont the ecu read bad???

from your name I'm guessing you have an s4
so, the s4 computer could not care less if the emission plugs are connected to the solenoids or air. The primitive pcm does not have any feedback sensors to let the pcm know that a requested function actually happened, also the pcm does not have any amperage monitoring circuits for the solenoids to monitor their operation.
