whats this thing

[Plankton]

The four metal lines that come out from under the manifold right under the two fuel inlet lines, i have no clue how to conect the canister thing that those four lines connect to. Wondering if anybody knows what to do with that thing.

il try to attach a pic to give you a better idea of what i'm talking about thanks

[fallen180sx]

just trash the canister.. cap the lines off. its emissions. waste of time.

Actually it's just a vac canister. If that is a vac. actuator attached to it, I'll give you $15 shipped for it.

as for hooking them up see my FAQ post

[Plankton]

i saw the faq post and that just confused the hell out of me, on my clip their were two elec conections that conected to the canister vac lines. and that whats giving me problems your post said nothing about those.

[mbmbmb23]

Do any of those vac lines control the butterfly valves in the intake?

-m

[Plankton]

not to my knowledge

hey biosehnsucht, that FAQ was really confusing to me as well. Its good information, but the picture speaks more clearly than the redundant worded explanation.

Is there another pic explaining the hose routing that you have on file or is this in the FSM somewhwhere?

Edit: I read the post again and I think the 3rd and 4th vacuum lines on the bracket control the secondary butterflies...

[biosehnsucht]

yeah i need to get on rewriting it etc

if you have two solenoids connected to it then probably it was originally an automatic motor..

yes, in the stock setup some of those lines are involved in the intake valve stuff

[Plankton]

so what would hapen if i hooked up the vac canister without having the solenoids hooked up ?

[Dattebayo]

You would have half the air coming in all the time silly.

Your mix would be off an you would be slow as crap.

[Plankton]

so i guess my best option is just to cap the metal lines off, or is their any other way i could go about this ?

[tyrannix]

and then what about the secondary butterflies? can they just run on a straight vaccuum hose from the plenum?

[biosehnsucht]

the easy way is yes to T the butterflies in along w/ the FPR to the plenum

better than leaving them open, since they will do something, but not optimal.

with a 'correct' setup the ECU controls them and decides to open/close based on RPM band and engine load

[float_6969]

I've got them set up with a small "inline" vac canister that I pulled off of a ford. It's prob only about 2/3 cubic inches, but it works nicely. I've got the SDS keeping them shut below 3500rpms right now. I'll need to get to the dyno to figure out exactly where I need to open and shut them. But at idle, they make a noticable difference. When I've them them open the idle seems rougher and slower. When I close them, the idle improves and idles a little faster. I don't know how much difference they make with a stock flywheel, but with the lightweight one that I have, it's quite noticeable. The car is eaiser to get rolling from a stop (less clutch slip), and seems to buck less if I bog it. It's not V8 torque, but it's better than w/o them.

[biosehnsucht]

can the SDS be set to turn on/off using engine load % or engine load % at X rpm? otherwise you can only tune it for WOT
