received my ultra-guage
 
ultra-guage came in the mail today. i bought the guage because i had upgraded to a corksport stage 2 SRI and their high flow cat back exhaust. read on here that i should be monitoring my fuel pressure so i sprung for the ultra guage.

question is... for those who have one, what is the most important, or what guages are you currently using. also, i couldnt find a guage that said "fuel pressure" exactly, so what guage do i need to be looking at.

thanks guys

I have one. I have 6 gauges on the screen and they are the only 6 I use.

Boost
Intake Temp
Coolant Temp
Fuel Pressure
Battery Votlage
Can't remember the last one...

If you got the EM version it measures fuel pressure, if you did not get the EM it will not have a fuel pressure gauge. ASsuming you have an EM, it's in the list with the rest of them. I know it says something weird like diesel fuel pressure or something but that's the one to use, it's the same shit.

yea its the em model. i figured out the fuel pressure guage, but why boost? the pu's already have a guage

this is not true. i have the first round of ultragauge (not EM) and it reads fuel pressure. EM reads AFR, which i would monitor if i had it, and gives you boost, instead of just absolute mani pressure. the EM also has some other things that i do not find pertinent..

i monitor:
fuel pressure
LTFT
ignition advance
intake temp
manifold air pressure (remember, i no have boost on mine..)
MAF g/s

really, fuel pressure and LTFT are the best. they will let you know if you have any pre or post boost leaks and let you keep an eye on the health of your fuel pump.

i'm not sure why you can't find fuel pressure. i just checked on the UG website and they call fuel pressure just that, 'fuel pressure (PSI)'

maybe you're retarded?:loveweed: edit: nevermind, saw you found it.

i have coolant, fuel pressure, ltft, stft, intake temp, and load

That's right. It's AFR. Which is the 6th gauge I use.

It does but it's just that stupid digital vertical line. The UG's boost/vacuum gauge is numerical which is a lot clearer. For example, I think anything between -1 and 1psi of boost just reads 0 on the OEM gauage whereas the UG would actually tell me its -0.87 or .23psi or what have you.

That said, both the OEM and UG boost gauge are just reading the ECU. If it really matters to you (and when I'm done my BT build it will) I'd get a standalone boost gauge with its own sensor.

on the website it says stright up "fuel pressure" but on the actual menu it says something different and i wasnt sure if that what i needed. im a bit retarded when it comes to this stuff tho, i am new to the whole scene so forgive me for my ignorance. what exactly is LFTF and what does it mean?

edit: nvm i figured it out, basically if my sftf or lftf is in the double digits there is something wrong, right?

ms3rick 08-10-2012 01:51 PM
Fuel
Boost
Fuel trims(both)
Both two change a lot as im in process of tuning..

Load, g/s, afr, timing advanced

LTFT...and it's long term fuel trims.

Basically your short term fuel trims are representing various changes in fueling over a short period of time (changes that happen several times a second)

Long term fuel trims are essentially changes in the STFT's averaged out over a period of time.

I know on custom tunes most people shoot for +/- 2% but I've read stock tunes can see a +/- 5% variance. I'd presume anything +/- 5% is ok.

Fuel trims are worth monitoring but the ECU is making the changes to the fueling that it makes to maintain the AFR it's programmed to shoot for. Those are ~14.8 at idle and ~11.2 at WOT. The stock tune is pretty rich.

As long as you don't see much difference in those values then you're fine.

ms3rick 08-10-2012 02:28 PM
My long terms are .78 unless I'm off throttle/shifting :) they jump to 1.5 or some shit lol

ok i selected "Fuel Pressure (Diesel & Direct Injection) (10kPa)" and it was at about 430.0 at idle, and went up to about 1200 at close to full throttle. is this normal. i was told that if it drops below 1600psi or so im in trouble

Mine are around that at idle once the car is warmed up. I've been delaying the install of my Autotech's for months but even on the stock FP internals at WOT I'm 1650-1700psi and even at 1/2 - 3/4 throttle its 1400+

This is terrible advice, but find an open road where you can floor it AND have enough time to watch the UG for a second or two. It should be 1600+, otherwise you might have a problem. That's the downside to the UltraGauge over something like the AP, it does not log so you actually have to watch it.

ok so it should be at about 1500-1600 only when flooring it. i was under the impression that it should be around 1500 constantly. so if i floor it and it doesnt hit 1500-1600 i might have issues?

thanks again for being so patient with me. ive seen what happens to people who ask too many questions on this forum lol

Haha it's cool man, I'm not too far removed from being that guy.

1600+ at WOT. Any lower and there's something that needs fixing. Idle should be right where you are. In between is not generally too much of a concern, everyone focuses on those end points, but my experience has been that at half throttle and above its pushing a lot of fuel, like 1400+

update: i had the wrong guage monitoring my fuel pressure. went for a second run and it was at about 1650-1750 at WOT. so i think im good. thanks for your help bro. if i could buy you lunch i would lol

the ECU will set off a CEL if it is outside of +/- 25. cobb recommends +/-8. i see -8 at idle and close to 0 at WOT..

everyone has their opinions.. as long as you are happy, the car is running ok and they don't all of a sudden change.

865ms3 08-10-2012 09:38 PM
if they would make this thing measure KR id buy one right now

cesaros 08-10-2012 09:38 PM
how much did u get your UG for?

thinking about picking one up....AP won't ever happen for me, since I'm not interested in tuning my station-wagon.

Mine's been ordered, what gauge did you use if it's not the Fuel Pressure (Diesel & Direct Injection) one. thanks

mine was right at $70 shipped. i think they're now on the site for $78.. they have rebates and sales and stuff periodically too.

You will see 0 at WOT because you are in open loop. The ecu is not monitoring and making adjustments like it does in closed loop. If your LTFT are too messed up, you will notice it because you won't be able to meet your targeted AFR. Then you need an AP and MAF cal...

true dat. i should have said that my LTFTs go to 0 when i'm getting on it, not necessarily WOT, but am still in closed loop..

thats the correct one, theres just 2 different options when it comes to measurments and i didnt have PSI selected.

get one man, cheap and works great. the mount is great too and will fit about anywhere. i put mine directly above the air vent left of the steering wheel and i was able to run the wires between the rubber and plastic part of the dash towards the door and hide the wires down in the bottom part of the steering wheel. looks freshh. easy to understand as well. pretty cool what the thing can do for $70

Thanks, how far are the boost readings off, and try the speed reading, here in Australia the whole Mazda range is around 5-7 kilometres per hour out (going slower than what the speedo reads)since 2004

heres where i mounted mine, i like it here. and you can run the wires in between the plastic and rubber part of the dash (as shown by the acessive amount of red arrows i used). then you can run the wires to the lower part of the steering wheel and stash the remaining wire the the empty space there. can barely see the wires.

i havent done speed, but the boost seems pretty accurate. maybe a little lower than what the stock guage reads

ms3rick 08-13-2012 02:13 PM
nice!

Wow, was just going to pick up a boost gauge after I get mine but for the price this thing is great. Love your mounting location. Did you use the mount supplied by UG or a different one? It looks like a different one than what shows is supplied. To me it looks like I could use the windshield mount from my old Droid phone since it should just hook into the back of the bracket.

i used whatever came in the box... the mount they supply you is great

Ezekiel81923 08-15-2012 12:54 PM
That's the same way mine is mounted, all the excess wire stuffed into the little cubby hole where the OBDII port is. Using the mount it came with, shits sturdy.

why not stuff the access wire in the bottom of the steering wheel? i can still use the cubby for my change

Ezekiel81923 08-15-2012 01:08 PM
It's either or I guess, I don't keep change in the car and it was easier to just tuck the wire right in to where its plugging in anyway

i used some industrial velcro brand velcro. a strip of loop on the sterring column and a strip of hook on the bottom of UG..

I like it. Thanks for the pic.
