Vaccumm Gauge install

[ej20i]

hey guys, any of u have install vaccumm gauge in a fd....was wondering where u guys install the hose and where did u get the electrical signal and how to tuck in the hoses in the dash and stuff...

[ndeuro_]

lol i did it in my euro. its easy. the vacuum i have to take a pic n show u. but for the power. just tap in to your ciggie lighter.

[ej20i]

argh....and where does it connect to as in the hose in the engine bay....ike to the air box...

[aaronng]

Why??!?!?!

Get an oil pressure gauge. It also moves, but tells you vital and useful information.

[ej20i]

harder to install???wad bt air fuel ratio???

[buzz]

air to fuel hooks up to your O2 sensor, and just hooks up to power somewhere.

There is colour codes for wires to the ecu somewhere.

:D

Stock O2 sensor is a narrowband, which reads "OK", "LEAN" and "RICH". It isn't going to work with a gauge. You need to plumb in an aftermarket O2 sensor somewhere before the cat.

Get an oil sandwich plate for $50, some 1/8" NPT plugs, liquid thread sealant and you're sorted.

take a photo of ur engine bay and ill tell u where to tap

hey aarong i also got the oilpressure its pretty cool and water temp. but yeah got an uninstalled blackout tacho. dunno how to install tacho --

You'll have to read the tacho signal off the back of the instrument cluster. If you have instructions to install an Apexi RSM, it will be similar. Find the tacho signal wire.

would i be able to hook it up from the ecu? i tried asking people on here a few months back but i got flammed lol

[ej20i]

i plugged my rsm to the ecu...it works..better than back of tacho i rekon..

do u have the ecu pinout?

[aaronng]

You installing into an Euro? Euros have a different ECU...

[ndeuro_]

use a tpiece and ur all set

[ej20i]

how do i get it out to the engine bay from the cabin??wad abt af ratio gauge?

[ndeuro_]

there should be a hole in the firewall. is about 3cm wide and a big grommit covering it

[ndeuro_]

I GOT IT **** YEAH i got it working
video up soon

[ej20i]

i got nothing in the firewall...no holes or anything

[ndeuro_]

there should be

Because your engine bay is so tight, you might have to remove the windscreen cowl so that you can get a clear view of your firewall.

[ndeuro_]

lol jack it up bro. but yeah im just happy i got my tacho working oh oh and u know it has two colours. white and amber. im gnna hook up the amber wire to my vtec. so when vtec kicks in it turns amber WOOT

[ej20i]

wad??Remove the windscreen???hell no...

[ej20i]

where can i get my ecu pinouts??i want vtec pin outs

[ndeuro_]

whats ur car model.

[ej20i]

Civic FD1...R18A Engine

[omgzilla]

wad??Remove the windscreen???hell no...

Not the windscreen - just the cowling (the plastic trim at the bottom of the screen).

[ej20i]

oooow...lol...

[Frost_FD]

I heard the hole is just under your accelerator pedal... i found this out after drilling a hole under the passenger side floor mats.

Get an oil sandwich plate for $50, some 1/8" NPT plugs, liquid thread sealant and you're sorted.

sandwich plate won't work with the fd, because there just very little room where the stock oil filter is, don't waste your money on it.

[ndeuro_]

hook it up to your oil sensor on ur ecu. but in that case you have to get an electronic gauge.

ps. applio how did u do ur light. its so purrrty

[applio]

here is my little setup for my gauges

all the wire go though the little plastic of the little triangle window

here is the wire comes out at the engine bay

http://i101.photobucket.com/albums/m47/ebuyproduct/DSC03574.jpg http://i101.photobucket.com/albums/m47/ebuyproduct/DSC03575.jpg

here is where i tape the "t" piece of the vacuum hose
http://i101.photobucket.com/albums/m47/ebuyproduct/DSC03576.jpg http://i101.photobucket.com/albums/m47/ebuyproduct/DSC03578.jpg

here is where i hook up the oil pressure sender and oil temp sender, tried with the sandwich plate, but no luck at all, it just tiny little space down where the stock oil filter is, so i custom make some hose and adapt to where the stock oil pressure sensor unit is.

i mean ur headlights bro looks tough

wad do u guys think of this, wads electrical gauge...means??

Electrical means it uses a sensor, which sends and electrical signal to the gauge. That is the type you should get. The other type is mechanical, which has the vacuum line running all the way to the gauge, which you do not want.

[ej20i]

where can u get that electrical signal to the gauge??since eveyone is using the vaccumm line...is it like easier or something?

[aaronng]

The gauge comes with an electrical pressure/vacuum sensor. You plumb that into your vacuum line. The output of the sensor is 2 wires which send the signal to your gauge.

If it was a mechanical gauge, you put a T-pieces and run a rubber vacuum hose all the way into the passenger compartment and into the gauge.

[ej20i]

ooo...so it relly works the same way??plugs into the same line??
benefit would be...smaller wire, easier to hide??
am i gettin this correctly?

Exactly! :thumbsup: Another plus is that electrical wire is less like to fail with age than a rubber vacuum hose running all the way into your cabin.

[ndeuro_]

maybe i should change my one to electrical

[ej20i]

got my gauge finally installed, but i do have a question
when the car idles..the gauge reads out 15 but when i floor it the gauge reads 0???

That's vacuum for you. :)

[ej20i]

so its not the other way around??well i thot wen it suck, it will go up but how come it goes down!??!?gravity?!?!hahha

It shows gauge pressure. The gauge pressure of the atmosphere around us is 14.7 psi. When you have suction, the pressure drops, hence it dropping from 14.7psi to 0psi. If you want the pressure gauge to go up, you need positive pressure instead of suction, which means TURBO. That's the reason why I tell everyone not to get a vacuum gauge for an NA car.

this is about how to read the vacuum gauge

arh
thanks guys

[ej20i]

heres my gauge setup....
when off, normally just black...because of the flash we can see the numbers

wad do u guys think??

[black8thgen]

IS THAT A MELO DOLL I SEE?!?! sick...

anyways thats looking pretty good, except seems really messy with the cables =D

[ej20i]

yea its a mello...yea i didnt want to drill any holes in the panel at all

[black8thgen]

ah okay, do those cables get in the way at all? or have u like taped them to the panel?

[ej20i]

they just tight...so they dont move or anything...they go into the air vent

[black8thgen]

ohh i see. thats alright.

[aaronng]

So, what benefits have you found with the vacuum gauge installed?

[applio]

the reading is strange, when car at idle should around between 17-21, 13 is not normal

I think his engine was cold, so the throttle was opened more than at warm idle.

[ej20i]

cold engine..
the benefit was
RICE!!!
