ok so ever since ive got a job last year at texas raceway ive been buying parts for a turbo set up with every pay check. piece by piece whole picture is growing. yesterday i got bored and me and a friend piped the intercooler (installed a while bak due to boredom again) to the tb and up twards were the hot side of the turbo will be. here are some pics of what we did.

after we put it on i was planning on just takin it off and leaving my sri til i could put the whole thing on. my friend i should start it so i did and it ran like normal. so i left it on, lol. we mounted the filter and we were done for the night. so now all i gotsta put on is the turbo manifold/ down pipe, turbo, and oil stuff.

the bov on the intake pipe it a cheapo off ebay. if it doesnt work than imma use the hks from the parts pic. im not using it first hand because the flange is broken so when ever i get the chance ill get it fixed. but 4 now im using what i have

what turbo is that? looks like a t3/t4. is that an OBX manifold? What fuel management are you using? You do have bigger injectors right? how bout fuel pump? What are your goals? How much boost? Are you sure you have all your bases covered?

That turbo is internally wastegated correct? I can't really see a WG in the pics but I think I see the vac line?

what turbo is that? looks like a t3/t4. - yeah
is that an OBX manifold? -yeah
What fuel management are you using? gonna try to get a unichip asap
You do have bigger injectors right? yep
how bout fuel pump? yep
What are your goals? eventualy 18 psi with a decom plate
How much boost? right now the wastegates at 8psi (probly wont go over 1 psi b4 a tune)
Are you sure you have all your bases covered? pretty sure
That turbo is internally wastegated correct? yeah
I can't really see a WG in the pics but I think I see the vac line? u can see the vac line, oil feed and oil return line

Interesting. Most of the hybrids I've encountered (including the one I had at one point) were meant to be externally ran. I hadn't seen any with internals until now.

Why did you chose the unichip? In the future, try to list all the details of a setup when you make threads like these lol that way you don't get bombarded with questions. :cool:

oh man, can't wait!! got enough questions there cypher? :)

I ask questions because he didn't list everything AND I wanna make sure that he hasn't missed anything

ElantraEvo

01-22-2008, 11:30 PM

haha i dont mind the questoins. but yeah ill try to post a long *** list soon lol.
i figured unichip cuz arent those the ones that come with alpine kits and stuff? if there was something cheaper and easier a would totaly go for it. but hope fully for now a good dyno tune from alamo or redline will be fine.

Cypher

01-22-2008, 11:35 PM

Aweomse. That was your 5th post so now I don't have to approve them anymore woot!

Well, the unichip is what used to come with the alpine setups. Alpine, for all intents and purposes, is no longer in business. A few people, felix comes to mind, have had the unichip crap out on them for whatever reason. The chip itself never had a good tune in it from them so, there were issues with "hiccups" and they didn't have a good transition from offboost-boost.

Most people now run the smt6, its very popular in the hyundai community. Theres also one or two running the AEM F/IC and having great luck with that. If it were me, I'd get something that I wouldn't need a shop to tune. The power to change your tune on your own is a great ability. Boo to relying on others.

ElantraEvo

01-22-2008, 11:41 PM

i was looking on the smt 6 site and trying to find out as much as i could bout it. i think hearing about it from actual users would help a great deal. (just might make a thred for that lol)
and yeah relying on peeps sucks but since ive givin up on being patient just this one ill have a shop do the tuning.
oh and pep boys did my injectors and fuel pump a long time ago, so imma just get an adjustable fuel regulator to try to get a bit better performance.

Cypher

01-22-2008, 11:49 PM

A fuel pressure regulator won't help you at all unless you convert to a return style fuel system. We have a returnless style.

What'd you mean they did your injectors and fuel pump? You put in larger injectors before you even went FI? thats just a waste of gas. If so, what injectors and what pump?

ElantraEvo

01-22-2008, 11:56 PM

the fuel injectors were 290cc and the fuel pump i dk what brand but they said its a 250lph pump. once i got the car i was at the drag alot. besides the clutch being completely useless at 50k miles and the tires being bald, the next thing to go was the fuel system. i dk. i just had the car for maybe a couple months and hadnt done anything to it. we pulled it to pep boys and after the 90$ diagnostic and a bunch of crap from them bout racing a hyundai, they offered to put it better stuff. so i said ok. all together it costed 800 bucks!!

and waste of fuel, hell yeah i was pissed about that. mpg went way down.

i know bout the return line off of a fuel regulator, how hard would it be to run a line back to the tank?

Why are you letting pepboys touch your fuel system?

On a side note: I thought I was the only person to paint the dipstick red! It was one of my first mods! LoL!

Unichip : I wouldn't recommend. You can't tune it yourself. If you get the kit from alpine, the tune sucks. And unichip authorized dealers charge a ****load of money to tune it.

Dragonis

01-23-2008, 02:21 AM

looks like its coming along good, are you still gonna use the sfr ecu?

NY2002ElantraGT

01-23-2008, 09:58 AM

If your gonna get the SFR ECU, i have the map sensor, brand new in box.

and felix, my Unichip tunner only chargers $100/hr which is really good. Unichips are huge with mustang guys

KeWLKaT

01-23-2008, 10:43 AM

Well that's still 100$ an hour more than it would cost one to tune his SMT6 by themselves, lol.

MOST people if you say "unichip" to them they will either go, "wtf is that?" or "eww why?"

so true. :bondage:

NY2002ElantraGT

01-23-2008, 01:30 PM

whoa whoa whoa. "unichips are popular with mustangs"? who told you that? Most of the mustang/ford guys like the programmers like the SCT. With those they can reflash their stock computer and still make great power and retain all factory stuff without hacking up wiring. I've seen 2005 mustangs supercharged with their stock computers using the SCT. This was a huge deal when they came out because they use a torque based ETC (electronic throttle control) and it was a issue to figure out a way around that.

MOST people if you say "unichip" to them they will either go, "wtf is that?" or "eww why?"

YES, SCT is the most popular tunning choice for stangs, i wont argue that. but my buddy has an old fox body that runs low 10's, has a 5 page spread in Muscle Car Magizine and uses the unichip. he's been using it for about 2 years now and said no problems. also he said it may not be the best, but everyone he talks to with stangs that has it, loves it.

looks like its coming along good, are you still gonna use the sfr ecu?

yah im gonna first run the car with the stock ecu and see how it runs. the ill put the sfr in and see how it runs with that. im sure ill stick with the sfr lol. but even after that ill still need a piggy back?

also i was wondering about cels coming on after the install. the obvious one for me right off the bat is not having a cat in right away. but what other cels will i have to watch out for?

KeWLKaT

01-24-2008, 12:48 AM

If you have the SFR ECU you wont have a cat code.

Why? Because it doesnt even use the oxygen sensors (from what jay was saying).

NY2002ElantraGT

01-24-2008, 11:51 AM

do you have the 2.5 map sensor from SFR? if not i have it, its brand new

Dragonis

01-24-2008, 10:52 PM

you shouldn't have any, i dont and i dont have a cat on. Also, running at 8psi you dont need a piggy back with the sfr ecu, but it is recommended if you want to tune

only1db

01-25-2008, 01:31 PM

if you have a reflashed (KDM ecu) and its set to your boost levels...why would you need to tune it further with an outside source?

Cypher

01-25-2008, 01:49 PM

fine tuning. The tune on it isn't going to be perfect. Duh

only1db

01-25-2008, 06:38 PM

duh...but how much "fine tuning" can you actually do with a SAFC....there arent enough points to get it "perfect"

Cypher

01-25-2008, 06:52 PM

There may not be enough points to make it "perfect" but with a general remap already in place, it does pretty decent.

NY2002ElantraGT

01-25-2008, 06:56 PM

the Neo is pretty accurate. i watched it being used on my buddy Nicks' v6 tibby. along with the zetronix it worked well

NY2002ElantraGT do you have the 2.5 map sensor from SFR? if not i have it, its brand new

no i dont. pm on how much you want for it then ill let you know if i can even try to buy off you. im payin off a ticket with my extra cash so i i need to know how much to save lol

WOW DEREK

WOW WOW WOW

You are a Hyundai tech and you can't recognize an OEM Beta2 MAP sensor? (obviously modified for boost on the internals), but the exterior is 100% identical!!!

You have this on your own car!!!

OMG!!!

only1db

01-26-2008, 06:28 PM

whats the difference...obviously...it looks the same...but if it comes stock 2.5 bar...thats not normal...ours are 1 bar....

KeWLKaT

01-26-2008, 06:39 PM

Erm no, ours are ZERO bar. If ours were one bar then we would be able to go up to around 14 psi with no problems and no need to clamp. LOL

And...

but if it comes stock 2.5 bar

erm... one post up...

obviously modified for boost on the internals

ElantraEvo

01-26-2008, 06:53 PM

well i havnt seen the inside of the stock sensor since i havent had a readon to take it off. whats the major difrence? is the inside of the 2.5 like reinforced so it woke fail under pressure? make sense to me just not sure if its a corrrect idea

Cypher

01-26-2008, 06:56 PM

Its not that it fails under pressure, It just can't read high enough. I honestly couldn't tell you what was modifed with it.

only1db

01-26-2008, 10:06 PM

ok now i get it....the outside did look the same...just curious what internal mods there were too it...

Dragonis

01-27-2008, 12:16 AM

i have the same one, and honestly it looks like nothing was done to it

KeWLKaT

01-27-2008, 02:48 AM

ok now i get it....the outside did look the same...just curious what internal mods there were too it...

Well it depends on what kind of a sensor it is... Could be piezoelectric (doubt it since it's a passive sensor), strain gauge, or perhaps variable capacitance. I have a spare MAP that would be cool to open up and check out, but I don't think I'll scrap a 50$+ sensor just for the sake of the conversation if it's not totally junk.

It could be as easy as tweaking/changing the potentiometer(s), or adding an in-line operational amplifier.

I checked the HMA ETM and it doesn't provide any info on the schematics about the construction of it.

UPDATE:

Ok... found something.

Looks like I guessed right, it might work with variable capacitance.... Here's a diagram of a ''normal'' MAP I found in google books:

http://www.elantraxd.com/forums/attachment.php?attachmentid=7193&stc=1&d=1201416379

To modify it, it depends... Perhaps you need to physically modify it's position (the plate on top). If it's just programmed to have a certain plateau value then you just reprogram (by adding/removing components) to the circuit on the inside of it.

it's not from a beta2....
it's from a diesel car they have over there....

KeWLKaT

01-27-2008, 09:12 AM

Wow that's completely random lol.

It's interesting that the connector is the same and the sensor has the same physical appearance!

only1db

thats what i'm saying....they have turbo diesels...ok i'm not out of my mind!

Go Turbo Diesel !!! My mom and dad both drive turbo diesel injectors. Love them! Volvo V70 2.5 V5 TDI.. blazinnnnnnn

Denisst99

01-27-2008, 04:17 PM

why would they completely design a new part when they only have to change the electronic part of it?
it's like the GM MAP sensor..
1 bar (na) 2 bar (15 psi) 3 bar (30 psi) all have the same exterior plastic housing,only the electronics insides are different and they added tabs inside the conenctor to prevent mix-ups (those tabs can be removed easily)

KeWLKaT

01-27-2008, 06:54 PM

Well it's still a modified Beta2 MAP then I wasn't totally wrong hehehe

ElantraEvo

01-27-2008, 08:57 PM

well maybe some one can figure out what the modifications are. once i get a new sensor for the remapped ecu than ill see what i can, well see lol. i think this would be really helpful so that peeps in the future dont have to buy a totally new sensor.

Denisst99

01-28-2008, 11:18 PM

it's not modified. .it's made that way, the only thing that is the same is the external plastic housing,the internal electronic sensor part is different
nothing much someone can do at home...

KeWLKaT

01-28-2008, 11:20 PM

I think we're all agreeing that it's not the same now. I tried to make a joke out of it, but it seems it didn't work :(

i care because i might be able to get hooked up from our general market people in miami....

they also do training for central and south america...hence why i know so much about those other vehicles. and why i have pics non north american cars.

so if anybody knows please post up

KeWLKaT

01-30-2008, 11:17 AM

Why can't you just look at the part number and check it out on the system? I mean, justin does have it in hand.... For a Hyundai dealership employee I would've expected you to think about doing that a long time ago if you wanted to know exactly, lol.
