Just like it says. I changed all the vac lines long ago. The pressure sensor is connected directly to a nipple on the LIM. Is here supposed to be a check valve or restrictor on that line?

If so where can I get one? check valve is a duh thing, but restrictor?

And what difference will it make if its not there compared to having it?

 

There's a restrictor about an inch from the end (on the IM side) in the stock line. On some cars fast changes to pressure (ie, slamming throttle plates open/etc) will cause it to hesitate.

 

heh... and the TB mod doesn't do that anyway? Where can I get a restrictor at?

 

You can make one from a scrap piece of plastic.
Take the smallest drill you have & drill the plug almost through.
The finish the hole with a straight pin.

Place it in the line near the pressure sensor for a short delay in sensing boost.
Place it near the IM for a longer delay in boost sense to the ECU.

 

I used a small wood dowel once, with a 1/32" hole drilled through it, until I found a replacement...

 

N/A, and I was slightly confused, you mean to put the plastic with a hole drilled in it, into the line?

 

indeed

 

suckage into intake?

 

It's generally a bit bigger than the hose itself, so the hose holds it in place, not to mention it's larger than the nipple, so good luck sucking it into your engine.

 

Um anyone have pictures of this resister pill or at least a make shift one?

 

The restrictor “pill” is essential to every rotary engine because it buffers the pulses that are created in the intake. Without this pill, the pressure sensor goes crazy.

The pill looks like a Tic-Tac but only smaller. It has a small hole down the length of the Tic-Tac that is about the same diameter as a needle.

 

if anyone has an extra one let me know I'll buy it from you

 

I got my "spare" from Mazdatrix, along with my "spare" boost sensor & attached vac line...

 

So how small does this hole need to be? Vac line is what... 1/8" ID? Are we talking the hole only needs to be the width of a pin? or a pen?

 

Closer to a pin than a pen...1/32" was actually a little big compared to the stock pill...1/64" would probably be closer...

 

Can one of those green/white check valves be used? Or is it necessary to flow in both directions?

 

wait... what?

Restrictor? Uh, thought it was just a vac hose from the LIM to the PS.

Unless this is a "DIY" mod, there isn't supposed to be one there...



From the S5 FSM..

Now I'm assuming this is N/A considering the thread starter has a S5 GTU...

so wayne, does this help in any way or something?

 

I've never seen one of these, nor has my car ever had one...

Hmm.....

SOOOOOOOOOOOOOOOOOOO much **** wrong with my car!!!!

Jesus!!!!!!!!!!!!!!!!!!!

I can't WAIT until I get EVERYTHING working right... will be like a whole new car.

 

Just because it's not in the FSM doesn't mean it's not there. Go pull the IM side off a stock car and squeeze about an inch up from the end and you'll feel it, then peek in and you'll see it.

 

Sorry, I just try and "resort" to the FSM, because of all these "FSM Gods"... so I try and just STFU and go by the FSM.

Everything about this car is ******* *** backwards, INCLUDING THE FORUM! Ask a question, told to search. Search, you pull up threads of other people asking and being told to search. Then you have the "FSM Bitches" who tell you to just read the FSM (including myself) - then when ya do, NOT EVERYTHING IS EVEN ******* COVERED!

Isn't that just great????

 

Lol, calm down. Sometimes instead of typing a novel for every answer, it's much easier to reference an FSM section, especially if there are several steps involved. Either way, we're trying to help you. Now, if you told us that you've read the such-and-such part of the FSM, but you don't understand this one particular step, most guys will be more than happy to enlighten you

 

I saw the orifice in the parts breakdown a ways back and thought 'what the heck' , then promtly forgot real quick

Dont knock the forum too much, it'll save you many times over. At least it did me.

 

You talkin 'bout me? Reffering to the pictures i post sometimes? Sorry, pics help me, words don't do squat

Still a little (read:sarcasm) ticked off at my freaking MOP, and the 3 gushing knuckles as a result from them. Really makes typing fun!

-sigh...

 

So does the restrictor belong nearer the LIM or nearer the sensor?

 

The LIM...About an inch or less into the hose...
