Tell us more what is FICD, what does it stand for and how does it work to increase the idle speed of the engine?

Is it being used to decrease the stoichiometric ratio or increase the amount of airfuel mixture electrically?

fast idle control device
its basically an adjustable actuator where it allows an amount of air leaked into the engine to increase the engine rpm, when the aircond kicks in
only works for fuel injection engine as ecu compensates the bypassed air with fuel, hence increasing the engine rpm

no it is not used to increase or decrease the air fuel ratio... it is not a piggyback ecu

Just to confirm tht FICD is only being used in carburettor vehicles?

Compressor problem you either get no air cond or air cond with hot air (magnetic coil) so it has to be something else.

Alvin, I hv an assumption what if the idle speed is already low but with the aircond comppressor jammed up due to lack of compressor oil?

FICD is used on cars with EFI only. But this thread here http://www.zerotohundred.com/newforums/car...cnf40-4g15.html  shows that carbs can also use.

I was told that compressor lube is in the gas that is circulated within the system.
*
So, U'd really confirm tht FICD can be installed only in fuel injected engines?

As for the compressor oil, yes, it is being circulated together with the refigerant. Tht was vat my assumption is.

Did you bother to visit the ZTH thread I referenced? I said it was intended to be used on EFIs, but in that thread someone successfully hooked it up to his carbie. Still, what's it to you anyway? You running a carb or EFI?
*
I didn't visit the link posted but will go have a look later.

The reason I was asking is because of I saw U were saying "FICD is used on cars with EFI only", didn't U?

As the matter of fact, it isn't only tht car mentioned in the thread has managed to get the FICD installed, there are many carburettor inducted cars out there tht are fitted with FICD, one of a good examples is the VPC22 (Nissan) with A15 carburettor engine.

U may go and clarify with any automotive air-cond contractor or workshop if U are unsure bout FICD on carburettor running engines.

I'm driving a fuel carburettored Saga LMST.

that toyota ficd is meant for fuel injection engines... as for carburetor engines, they have their own non-adjustable ficd which hooks up to another idle load compensator (something round look like ufo) which pushes the actuator down to control the carburetor idling...

means for fuel injection, u jz need an adjustable ficd.... for carburetor, u need non-adjustable ficd and that ufo thing (idle load compensator) to work...

U were telling tht FICD "only works for fuel injection engine" in Ur previous post, I didn't know tht U were specific to the Toyota FICD.

I don't understand in a good way y would U think tht was a rant and retaliation? yawn.gif

We all known tht FICD is being used on both EFI and carburettor engines regardless of stock or not.

The facts?

Perhaps U wanna re-read post #22 vat it was said, can U see the words "stock item" and "retrofit" tht came out later on post #28?

And for post #19, did I see the word "only works for fuel injection engine"? Were U refering to which specific FICD?

I would not treat tht as a rant and retaliation, but for those who feel offended, I don't know yawn.gif

i dont understand those bolded words...

I'll act blur if I were U. But since those words were not directed to U, perhaps juz 4get bout it.

Some1 was trying to act smart and confusing the forumers here without even knowing what has he wrote and didn't even bother to know it.

I know there r many "kids" and colleage boys here have no idea what they r posting and simply "tembak" even they r not sure vat they r posting thus confusing other forummers. These r the fellars who deserved of being "f**ked".

But aren't U suppose to make sure tht Ur f**king the right ppl b4 commencing the "fxxking operation"?

He muz have thought tht I'm a colleage boy or those "kid" who simply "tembak" nonsense without having the sense of logic or those who simply copy n paste the info here frm other source thinking they r very smart.

Shouldn't he look at the mirror 1st of his face 1st b4 posting? Dew....

Hey girl, go read back your post 21. If you're still feeling butthurt, maybe we should meet up for a TT.

It seems like U had no idea I was replying to post #19 which suggested "only works for fuel injection engine" and didn't specific Toyota/Denso FICD.

Butthurt??? I can't find this word in my dictionary....

Meet up? It seems like U prefer discussion to be done in another alternative way do U? YES
