Alright so I'm putting an FD UIM and TB into my FC and am not sure what some of the "open" things are on the manifold. I checked the FSM and looked at some blockoff plates and I kinda have an idea about one, but I'm still not really sure, plus I don't know what to search for in the FSM. So anyone wanna help me out? Here are the pics of what I'm trying to figure out.

 

First picture, im pretty sure is the isc, the idle system control, second and last picture are the acclerated warm up system solenoid and pipe.. You may want to keep the isc, but if your ecu won't control it, why not just block it off. I have some block-off plates for these if your interested, so just lemme know.

 

Is that the only way to adjust the idle on an FD or are there other ways? I haven't received my TB yet so I haven't been able to look and see if it has something like a throttle stop screw, but if thats the only way to adjust idle I'm gonna be screwed

 

you still kept the double throttle but you can remove that

just keep the idle speed controller, and air intake thermosensor

for vacuum lines youll need the map sensor line, the one for the purge solenoid in the front and also one from the oil filler neck containing the pcv valve.

of course you cant do any of these without a totally reprogramable ecu

 

there is a air bleed valve in the TB, you can use that to controll idle, but it will be hard to cold start without the isc or some method...ie...foot

 

I agree, I'd remove the double throttle, and even if you don't wanna remove anything for some reason Just remove the plates.

 

I'm going to be running this on the stock 2nd gen s4 ECU so I will not be keeping the idle speed controller most likely. Double throttle as in the double throttle plates? Yah those are coming out, I already know that.

Why would I need those vac lines? On my 2nd gen I'm currently running 3 vac lines, one for FPR, one for pressure sensor that hooks into the LIM, and the other one I'm not exactly sure what it is but it also hooks into the LIM.

 

Yah no big deal, already have a TB mod done to my 2nd gen right now that has those same supposed problems that everyone seems to have. It takes literally 15-20 seconds after starting it up of holding the revs at 2k while I put my seatbelt on and get the music going before it's ok. I also run my idle at about 900 though so that helps.
