Missing link
 
Whats up every one. I'm new to posting here but I've been reading them for quite some time now. I was curious. Is the "Missing Link" just a machined Check valve or does it have other functions to it than that?

nope, its just a machined check valve. its garbage.

check valve is supposed to have a smother transition to boost right? is it mandatory for a custom turbo kit?

Check valves or a missing link are necessary when you aren't running a chipped ECU because the stock ECU cannot read boost or positive manfiold presssure. You are "masking" the boost from the ECU with either of the two.

Not entirely. If you run the AFC hack you will not need check valves because the AFC scales down the map signal itself.

whoops...sorry, completely forgot about the VAFC for a second there.

I ask cause the product info I have found briefly talks about bleedoff for smooth transition of Vac. to Boost. With check valves its either open or closed right. So what the hell are they talking about?

Bitch read the faq. There is more knowledge on this site than anywhere else. If you ask one more dumb question like that then you might get banned. READ UP, then ask

Relax... It's his 2nd ------- post. ::)

At least he didn't come on and say "Someone tell me if I need to have the missing link with my coded UberCrome running the hack with a 12:1 FMU? I've searched! Honest, I have!"

Damn, hostility off the get go.
It was an honest question. I have read at least a couple hundred posts on here and "none" of them explain exactly what a missing link is. They all explain why its needed however. I am fully aware of the need to hide boost. I was just asking if maybe the missing link did something other than hiding boost that makes it so much better than a few check valves from the pet store.
Also, if getting called bitch every time I ask a question is going to be the standard, then ban me. I won't fell to bad about it.
Thanks to you other guys for the answers.

There are only three things you need to know about the missing link:
1. All it does is hide boost from the MAP sensor.
2. It looks better than having multiple check valves in your engine bay.
3. It's more expensive than check valves.

Hope this help you.

This is HMT, check valves are the way to go instead of spending a bunch on some pretty lookin thing. Make your car ugly and fast, and you're good to go ;D

I'm currently ammasing the parts for my HMT. I've got a very small but quick spooling TB0205 internal w/g off a nissan 300zx.(Late Eighties if your interested) A crap load of 2" exhaust piping for my charge line. 60$ Autometer boost gauge. I am designing my own electric BOV.(I'll let you know how that goes) I have ordered the missing link to tide me over untill I have the time and money for learning and actually chipping the ECU.
I am cramming all of this into my 97 Civic D16y7. I know I'm gonna get the you won't get much PSI talk but I'm only looking to bump up my torque a bit.
Thanks in advance.

A check valve (missing link included) evacuates some boost to the atmosphere so the MAP doesn'T see it. Usfull only with fuel management systems that are 100% independent of the honda fuel system, such as and additional injectors.
Any check valve is a very crude way to clip MAP.
The best thing (if really you need to prevent the ECU from seeing any boost) is an electronic boost clipping device that will cut the voltage of the MAP just below 1 psi (when the honda ECU triggers a safety cut off)
That way, no boost is evacuated to the atmosphere and you are sure the MAP reads Exactly like stock. PLus, it's maintenace free as opposed to the missing link on which the tiny dump hole has to be cleaned periodically.

Such MAP clipping device, luckily, is CHEAPER than the missing link. I know a company that is offering them for 50$.
