what is most important to monitor w/ gauges? part 1

what is most important to monitor w/ gauges?
I am curious what you all recommend I monitor in my car with new gauges?

Voltage? temp? Oil Pressure? Fuel Pressure? A/F?


I already have a turbo guage from stock, so I'm looking for more critcal gauges.

I need 3 of them... so what would you suggest?
bluerex47 09-24-2005 12:30 PM

a search would give a lot of opinions, but to make it quick and easy....oil pressure or temp, egt, fuel pressure. Thats what most go with
essteaeye 09-24-2005 12:32 PM

to me atleast, gauges are eye candy, i mean you cant change anything so why even bother? Unless you have some type of EM and feel comfortable changing things around, then its different. I spent about 1k on the defi setup and ended up selling it weeks later since i got no use from them, but hey thats just me.
Thumper23 09-24-2005 12:52 PM

gauges are IMPORTANT, period, even more so when you start modding

why spend $30k on a car and not want to know its vitals?

anywho, back to the topic, definitely EGT, oil temp and pressure


why you ask, fuel pressure, unless your fuel pump fails, you've got a gas gauge, A/F ratio you can get off your EGT (running hotter, you're too lean)

of coures, you can get your oil temp off of your oil pressure to some degree (you can tell when its up to temp versus when its cold) but personally, I like to know if my oil is getting too hot that way I can back off some

i want a boost gauge, and the egt gauge along w/ the dual a pillar mount...where is the best to order from and nicest "looking" gauges.....

well, first off, what do you drive?

I got the Defi Link BF Amber gauges cause they very closely resemble the stock STi gauges. IMHO, the BF gauges look the best, but that comes at a premium.

[url]www.gaugepods.com[/url] sell the Lotek A-pillar pods, and they'll even paint it to match the interior gray

however, I ordered a Lotek triple meter pod and the fitment was marginal at best, I instead went with the triple meter hood
Matth3w 09-24-2005 02:54 PM

wideband a/f gauge is by far the most important. you cant tune a car with an EGT gauge, its not accurate enough air fuel ratio checker and there are too many other variables that affect it.

+2...definetley an aem a/f not those crappy autometer gauges that never seem to tell you anything...

that's very true if you're gonna do alot of self tuning

I don't trust myself so I let the pros do it ;)
Vampyr 09-24-2005 11:19 PM

so which manufacturer makes the best, most accurate gauges?
Defi?
Autometer?
GReddy?
SoareS 09-24-2005 11:21 PM

i would go with defi, but measure boost, EGT temperature, air/fuel ratio
Thumper23 09-24-2005 11:24 PM

Defi is a safe bet

and get electrical over mechanical

sorry, hi guys.... im new... just picked up my 05 mbp wrx on wed. and already have 700 miles on it... just got the windows tinted. also, what is the unit controller and why are defi gauges sooo much money? one gauge is like 168 and then the controller is 99 something..... how does this all work?

you need the controller for most of the defi gauges, and the ones that most people use on the sti's are the BF ambers since they match best. They also dim and the color and look is identical. I believe they have the same parent company: nippon seki (sp??)

Anyways its about 1k for the setup, its expensize since you need the gauges, control unit, and gauge pod which is anohter 150. The gauges are eletrical and they are JDM, hence they cost alot, but they are VERY precise and wortht he money if you have it.
SubieStyle 09-24-2005 11:41 PM

Boost, EGT, oil. ;)
veightkiller 09-25-2005 03:08 AM

^^^ oil press.
dcoty 09-25-2005 12:57 PM

Im getting the defis in boost/egt/oil press.

Tuning/modding w/o gauges is like doing open heart surgery without a heart monitor!

I saved my con rod bearings on my old car because I had an oil pressure gauge and saw a huge drop in pressure (oil galley plug wasnt put in correctly by the shop that worked on my motor). So before I do anything on my STi....gauges first :D

i still dont understand why every suby owner thinks they can leave out wideband AFR safely. im guessing people just dont want to spring the money for it.

[QUOTE=Matth3w]i still dont understand why every suby owner thinks they can leave out wideband AFR safely. im guessing people just dont want to spring the money for it.[/QUOTE]

why do you think this?

unless you're tuning it yourself, then I would say yeah, its important

but if you're not physically doing the tuning yourself, there is no need for one


EGT gauge does just fine for driving/auto-x/track days/etc
Matth3w 09-25-2005 01:37 PM

well no one mentions fuel press or afr gauges.

tell me what happens if your injectors go bad?
tell me what happens if your fuel pump goes bad?
tell me what happens if youre in a location or driving condition that changes the fuel?

i could go on and on.

I would say EGT would cover atleast 2 out of those 3

I'm not saying they're not important, but neither of those gauges are in the Top 3 of importance. Once you start adding 5 or 6 gauges, then sure.

IMO, in order of importance, its 1.) Boost, 2.) EGT, 3.) Oil (temp/pressure -> a loss in pressure results in rapid temp rise, has happened to me before, that's why I say either), 4.) AFR, 5.) the other oil gauge you didn't have, 6.) fuel pressure.
Matth3w 09-25-2005 01:49 PM

the EGT isnt fast enough or accurate enough to tell you. it will tell you, after its too late and damage has been done.

maybe if you're running the thing up near redline, which at that point, you're probably screwed anyways
Matth3w 09-25-2005 02:04 PM

too many ifs, ands or buts for me to worry about spending an extra couple hundred when a motor is worth thousands.

there were a ****load of times i asked someone on the clubwrx board in reponse to why did my engine blow, what was your afr and they had no clue. amazing.

You own a 30k+ car and wont spend $500.00 for some gauges? Hell even a cheap autometer gauge is better then no gauge at all..

Yeah so? Whats your plan to run triple A-piller, Triple clock pod and the autometter dash pod with 8 gauges? Why not just tose on a 8inch RPM gauge with a shift light and complete the riceness.

Sorry but unless you are tuning or building a race car there isn't any reason to run all those gauges.
EGT | Boost | Oil Pressure are the main 3 you want to run IMHO. If you can afford the rest and don't mind the clutter. Go right ahead, they can't hurt... Unless installed wrong and make a fuel leak or oil leak. :lol:
Matth3w 09-26-2005 03:08 PM

i dont think you need but 4 gauges. you can even leave out the EGT if you have AFR. boost, fuel press, oil press, wideband afr, and then EGT if you got the extra room. two behind the wheel, three on the pillar. or if youre more creative you can do other things (like custom pods or the clock etc)

How about I state my reasons and you tell me if I am thinking clearly (wouldn't be the first time if I wasn't)... I have a Hydra which can monitor AFR (I have the wideband option BTW) so for tuning I will be viewing the laptop and no need for a gauge in that situation. As for problems while driving, I can have aux map that will automatically throw my car into a limp mode quicker than I could ever cut the ignition. So given those two scenarios I still only see Boost, EGT, and Oil pressure making the most sense for continuous realtime monitoring every day. Of course I realize a lot of people may have some other forms of EM that is not quite so advanced and would have a much better reason for wanting AFR.

One other thing, I am getting ready to buy these gauges soon. They will go in a dash pod. I will not be using any sort of A-pillar pod. That leaves me with the two 52mm guage spots using the gauge bezel area (popular on ebay for cheap, has anyone used one and what are your thoughts?). After those three gauges I am considering doing a couple more because I do like a lot of info available. I would love to see the Defi BF done in 52mm so they will all be consistent. But I am stuck on which I would put there. I have roughly narrowed it down to AFR, Oil temp, fuel pressure, and coolant temp. Am I missing any worthwhile options on my second tier of critical gauges?

i have the ebay gauge pod you are referring to, i spent 16 bucks or whatever and it works 99.99 percent fitament.

offset to answer your question, you have AFR monitoring capabilities. when i say AFR gauge, obviously if you are monitoring it in another way that is also accounted for as opposed to strictly must have the gauge itself. i dont think about tunning without AFR. too many people imo are willing to give their car to someone else to tune, why not tune it yourself? if there are any problems you can fix it yourself.

i always give more respect to mods done by the person than mods done by some place they just had the money, dropped it off, and picked it up.
offset 09-27-2005 08:21 AM

Well, for some folks they may want to at least start by tuning with someone else who knows what they are doing. That is how I got started. But back to the AFR gauge; my point was in my situation would you agree that the three I mentioned made the most sense to monitor in realtime every single day? I think that is kind of a part of other people's question in some ways. Some people use a wideband AFR while tuning, but do not have the gauge mounted in their car everyday. I just figured I would throw that perspective in there.

BTW Thanks for the response on the eBay pod.
