removing black box - 85 accord -

[Coy]

its me again....

im very interested in this black box removal, but i dont think that the how to on the 3g will carry over to my gen, since mines a 3Bbl. if anyone knows anything about how i may get this done id like to know....

[A20A1]

I'd need a vacuum diagram... it shouldn't be too hard.

Anyways I'm still searching for a diagram...

[Coy]

you gunna find the diagram or you want me to?

anyways, im not sure what the deal was with the links or whatnot...guess its just stuff you found while searching.

[A20A1]

yeah just stuff i found... carb jargon, that may help explain a few things to me.

If you can find a diagram cool... you might want to look on the underside of your hood for a vacuum diagram sticker...

[Coy]

theres one on the underside of the hood, but i dont have a digital camera or know anyone who does.

ill see what i can find, if you find something let me know.

[Coy]

im trying to meet up with a buddy of mine to get a pic of the vacuum diagram off teh underside of my hood, and im gunna snap some shots of my my extra carb as well.

im trying to find the link on the writeup for the mechanical second on the 3g's

[A20A1]

it may be different you have a 3bbl

[Coy]

yeah i know....thats why i was gunna get some pics of the carb as well.

im just gunna end up takin a good highrez pic of the vacuum diagram thats on the bottom of the hood and sending that to ya as well. i was planning on take'n 6 pics of the carb...top, bottom, and each side

[Coy]

got the pics. i took a pic of each side of the carb as well, cause i would guess that the vacuum removal would also include the mechanical second...and since you cant drop by, you could (if you could be so generous) make me some diagrams for the conversion out or the carb pics. on a side not, i wasnt sure if i could get a good clear pic of the diagram (it was dark, and im unsteady) so i took a few pics of it...
Diagram 1
Diagram 2
Diagram 3
Carb from front
Carb from passenger side
Carb from back
Carb from driver side
Carb top
Carb bottom

if you want to resize any of the pics, go right ahead...i didnt want to distort the image so i left them the size they where on the camera.

[Coy]

mike you there?

[A20A1]

yup I'm here, I'm working on it... I can't be too sure what I'm doing since i don't know the contents of the black box... do you still have the camera?

[Coy]

naw, but i can get pics. i wasnt sure if you where working on it or if you had any idea that i had gotten the requested pics.

AIM me.

[A20A1]

Your pics didn't show #14 or #6 but I did my best.

Store all parts you remove just in case.

Under the choke and fast idle unloader there is an idle diaphragm... what vacuum hose connects to the idle diaphragm? Is it #32?

You have a second diaphragm on the other side of the carb with #6 coming off of it... they lable it as DASHPOT.

You need the #6 idle controller
You shouldn't need the A/C idle boost controller that uses #32

#14 I assume is the powervalve connected to the carb

#2 is the single vacuum advance connected to the distributor

#18 and #19 are for choke operation ( Choke opener / Fast Idle Unloader )

#17 is a bleed hose

Please let me know if #6 #14 or #2 are in any way connected to a Check Valve. Check Valves are orange on one end and clear/white plastic on the other... they connect inline with a vacuum line. If any are located between the manifold vacuum taps and the part connected to the # let me know.
#2, #6, #14 all connect to manifold vacuum... use any port coming directly off the intake manifold as a vacuum tak as long as it isn't already being used after you removed the vacumm lines. Manifold vacuum ports at the rear of the manifold make more vacuum then ones locater further towards the cylinder head.


I hope this pic helps... I'm kinda worried about where the air jet controller is... if there was any.

In the diagram I'm posting make sure you plug the unused vacuum ports on the carb and the intake manifold.

[A20A1]

Be very cautious the first time you start it up... be ready to adjust the idle screws, know where they are.

I'm wondering about #19 and if it really needs to connect to manifold vacuum like that... It makes me wonder if the 3G should have a manifold vacuum tap as well.

Also when looking for manifold vacuum taps... the thermovalves are not vacuum taps they are valves. Find a large or medium size metal port at the rear of the manifold and use the metal vacuum lines you removed to adapt the vacuum lines to the tap.

I see a FOUR port vacuum tap extendeing out of the manifold... #19 is the only one that uses it in the new diagram... I suppose it could be used to controll #14, #2, and #6... it should make for a clean connection even though it would get the best vacuum since it's not a rear port.

Currently in the diagram #2 #14 and #6 all connect to the vacuum tap on the opposite side of the manifold.


oh #25 can remain connected from the distributor port directly to the thermovalve if you choose... if not plug #25 port on the thrmovalve.

[Coy]

wow. thanks man.

ok, just for margin of error on my part, im gunna wait till my car becomes completely mine before i do that. im sharing it right now with my girl.

[accordlxi2.0]

hmm i wonder why honda went from 3bbl to 2 bbl.....
i mean would'nt one think that the 3bbl is better??

[Coy]

i was wondering the same thing. dont know what to say about that one

[A20A1]

I'm only 70% sure the diagram is correct.
So I'm glad you're not jumping into it.

[Coy]

yeah. as soon as i get around to it im gunna print it all out and answer your questions.

[Coy]

as far as the check valves there are only three of them. but there is another valve thing that looks similar, but its got tree hoses attached to it. its orange and blue and it goes to the cruise control stuff.

ill get more later

[Coy]

located #6 & #14.


so from your diagram it looks as if A-M (on the legend at the bottom), the air chamber, and the EGR are not used and can be removed right? of course the EGR has to have a vcover plate over its original mounting location.

any other questions or anything you arent sure about or you need some more info.

[Coy]

anything?

[A20A1]

You don't have to remove the EGR valve, you can just remove the vacuum line ( #16 ). But yeah if you remove the valve then you need to make a blocking plate.

Thre air suction valve needs to be blocked off as well if it is removed or you can just remove the vacuum line to the valve ( #5 )

[Coy]

the air sucktion valve that goes to the air chamber? ok, seems like maybe block it on the filter holder and the air chamber. if thats correct why not just remove the air chamber and block it on the filter holder. the air chamber has nothing hiding under it but has a line attached to the exhaust manifold. i was thinking get a Ex mani from a 3g since they dont have the air chamber connector dealio.

im still wondering about the things on the legend at the bottom of the diagram, thay are all being negated if im reading right.
