Meters ohhh Meters

[KingHaruan]

okie dokie...

we all know that there's a lot of acc. meter for that racer looks, so i really like to know how it works?, why we needs it? and the benefit of it? by having these meters other than eye candy purpose...

1. thaco - ok, i know this are for rpm (any other pupose?)
2. volt meter - purpose and benefit?
3. water temp - is it for the radiator ah?
4. vacumm - heard it is for pressure in engine (true ah?) why ah?
5. any other meter that u know (good explenation r welcome from all pros)

as knowledge is power, when knowledge is shared ;)

B) TQ

1. thaco for RPM
2. volt meter - to make sure your battery is not driven till dead la , if volt low then u know ur battery kong or altenator kong
3. water temp - same as the temprature in ur dashboard meter panel
5. boost - if got turbo then to see ur pressure
6. oil temp - oil temprature in engine
7. oil pressure - the oil pressure inside engine
8. AFR - to see ur Air Fuel Ratio - see ur tuning lari or not
9. EGT - exhaust temprature - also used to see tuning lari or not

this one same as vacum ah?

9. EGT - exhaust temprature - also used to see tuning lari or not

the meter in temp, how to see if tuning lari wor? lower temp means lari or higher temp?

 

[jinkl]

vacuum is ur air intake la brother
EGT not very very sure la bro..

read here
http://www.sdsefi.com/techegt.htm
they tell u difrence in AFR and EGT

EGT is Exhaust Gas Temprature with this they can do tuning too

wah, very technical link... TQ

 

[lozo]

vacuum meter is to monitor engine load..
correct me if im wrong :)

 

[malan]

jinkl..

can u help me to find place to install the Air fuel Ratio (AFR) ..bcoz yesterday almost 5 - 6 accessories shop i went but they dunno how to install this AFR..help plz

 

[simonchangwaimun]

AFR is to check whether ur engine running rich ,ngam ngam, lean
rich = too much petrol
ngam ngam = correct rationing of petrol + air
lean = too much air
correct ar?

 

[KingHaruan]

AFR = to check the air and fuel (correct kut)....

about the VACUMM, how ? how u fully utilize it? how to know whats wrong?
i need to understand laa...not fully familiar with all the meter function...

plus the rest of the meter cluster...anybody?

 

[KingHaruan]

:huh: aiyahh.... :( no one here to help this topic worr....isk isk... :( :(

Bro,

Vacuum meter to measure vacuum pressure of your engine (normally mesure in mmHg... this a very low pressure, below atm.)
Your engine is like vacuum cleaner which suck in air for combustion laa..
there's web sites explaining which I don't remember the address. You can search using Google.. just type vacuum gauge or meter...
The gauge can be used to do simple troubleshooting on your engine health.. if your gauge a bit lari-lari during idling.. then your engine might have a problem or two.. there's also a web site on how to troubleshoot your engine using the vacuum gauge..
I've use mine to monitor engine health (and for looks also laa..)

Hope that helps. :ph34r:

idling lari lari.. mine lari wooo... means got prob ar?

 

[autopimp]

I think you better go to this website.. I just found my printout on this website.. got info on how to read proper vacuum pressure ...

www.centuryperformance.com/vacuum.asp

Bear in mind it just show you what could've been the problem.. and do your own preminilary check.. for serious problem.. you still has to consult mechanic lah..

;) ohh....ok TQ...educational site... :)

IMAGE # WHAT YOU SEE DESCRIPTION

1 Steady Needle Normal reading (usually 17-22" Hg. in stock engines) Race engines vary "a lot" and in most cases will be considerably less.

2 Intermittent Fluctuation at Idle Ignition miss, sticking valves, lifter bleeding off (hydraulic), or just a BIG camshaft

3 Low, though Steady Reading Late timing, low compression, sticking throttle valve, carb or manifold vacuum leak (remember most race engines with a big cam and a tight centerline and high overlap will be naturally low ... you must decide your baseline vacuum reading)

4 Drifting Needle Improper carb setting or minor vacuum leak

5 Fluctuating Needle as RPM Increases Ignition miss, blown head gasket, leaking valve or weak or broken valve spring

6 Steady, but Needle Drops Regularly Burnt valve or incorrect valve setting (too tight), "needle will fall when bad valve operates"

7 Gradual Drop at Idle Clogged exhaust, excessive backpressure (extreme cases engine will die at idle)

8 Excessive Vibration that Steadies as RPM Increases Worn valve guides

a good discription/pic....very easy to understand TQ...

hey guys.. how many wires are there in a vac meter?? i know there is one pipe connecting to the engine right? other than that, is there any thing else?? coz if thats so, i wanna get it and install on my bike laa.. heheh... just for show

 

[KingHaruan]

Vyraz.... :) superbike or easyrider....if superbike sure damn cun wan.. :P

eheheh..
tell u dont laugh ok??
aint no superbike aint no easyrider..
just a crazy old rg.
trying to figure out how to wire an rpm meter but gave up.
so.. can anyone tell me??
how many wires in a vaccum gauge?

 

[KingHaruan]

wah....u like acc...still.... :) sure look cun wan....but takut if u pasang ppl curi nanti... somemore nowdays car kena pecah becoz ppl curi meter... :ph34r:
