    h23a1 plenum problem...?

    I am having trouble getting the butterfly valves to actually open in the plenum, and I think this is a huge contributor to why my car isn't running the way it should. any suggestions? or diagrams of vacuum lines that I could use to get that plunger to operate properly??

    thanks a bunch!

        It would be bolted to the bottom of your runners? Did you just replace the plenum? Or did you add A6 runners to an A1/4?

            Ok then it should have the box already. What ECU did you get with the engine? It should be a P14.

                this is an older picture. i've added a vacuum hose running from the intake tube over to that diaphragm. almost every hose diagram i've looked at has just confused me, and a mechanic told me to try this. but it still didn't do anything.

                  Well if you didn't have an A6 engine to start with, the plug for the box won't be there. You have to go get a 2 pin connector from the jy, hook the yellow/blk to a switched 12v source, and the other wire has to be wired to pin A9 at the ECU.

                    no, i had an f22a1. so wiring is the only thing i need to do to it? there is a plug on the side of the intake next to that diaphragm. where should the vacuum line run?

                      Well there's a sensor near the diaphragm, the temp sensor and it takes a 2 pin plug as well. The vacuum line for the diaphragm can go to any intake line on the manifold.

                          Let us know if you need help wiring the box up, that plug won't be there, your gonna have to add it. Do you have the line on the back of the manifold hooked up? It will have an odd plastic piece, believe it's white or orange, it's right near the manifold.

                          Wait, did you get the H23 harness with it? Then the plug is there, but it stops where you joined the H23 and A1 harnesses near the shock tower.

                            i actually used my original wire harness, which is pretty beat up. broken plugs and shit. lol. i plan on getting a custom harness when i can save up some money. i just happened to lose my job last year as soon as i started the swap. so it's been pretty rough. plus, i'm definitely a beginner so i'm still getting used to all the names for the parts. for example, what's the shock tower? lol.

                              oh, and the vacuum line can't run to the actual intake tube? it's gotta be on the actual manifold, right?
