Scott's a pooopy head
 

How the heck am I supposed to waste away my day at work if you're not on AIM you fucktard? HUH? YEAH THAT'S WHAT I THOUGHT!

Oh, btw, what should I put on my car... TXS TBE, wastegate port, and BC then wait for UTEC. Or...?

Re: Scott's a pooopy head
 

Bwahahahaha!

Wait for better engine management, or port your wastegate.DO NOT run a TBE without either of those two things, or BOOM.

Well, I don't think it would go "boom" but it would definitely go KNOCK KNOCK... Ohshits where'd my fuel go? *car slows down*

Jesse: suck it. :lol:

And BTW: better engine management won't fix the creep issue unless it watches your boost and changes the TPS once you start to overboost. Basically the only way for Engine Managment to fix boost creep is to take the foot of the pedal for you, which it can do now that the STi is throttle by wire.

The root of the creep issue is that even with the wastegate fully open, the car still increases boost. It's a mechanical problem... all the software can do it attempt to open the wastegate more, and once it's fully open, you're SOL.

IMO, TBE = port that wastegate! Then hope Subaru doesn't look in there if you need warranty work done... even though a ported wastegate can't possibly hurt anything (unless you fuck the turbo up while doing it), I'm sure Subaru will try to deny your waranty repair.

I vaguely remember saying I was GONNA PORT MY WASTEGATE IN THE FIRST POST! God damned you guys. READ :P

Yes, I know all the problems, that's why I'm gonna port the wastegate. I was more concerned with was there another route you guys would take?

Oh, and BOOOOOOOOOOOOOOOOOOOOBIES!

I brought up the porting for Matt, since he seemed to think that waiting for a better engine mangement solution would somehow fix the boost creep issue.

As far as your email regarding Boost Control... the XEDE is the only setup I know of right now for the STi and it controls boost. I haven't heard about UTEC for the STi, but UTEC and XEDE are equivalent products, so it should be about the same, if not a little better since the UTEC stuff is more Subaur specific IIRC. The holy grail of course is the STi ECU reflash, that way you gain access to the AVCS parameters, and that's when we'll start to see some uber-badass STis!

So, I'd avoid a MBC or stand alone EBC. I think Vishnu's Stage 1 for the STi, plus a ported wastegate is the way to go right now, but it's tempting to wait a bit longer and see what's up with reflashes in the near future.

Also, I hear ESX is working on a Project STi, so it might be interesting to see what they come up with. It should be out at the Buttonwillow track day March 22... and if I see it before then, I'll let you know what I can find out.

There are so many acronyms in this post my head is spinning. And I work for the government, the King Of Acronyms. :lol:

KOA. :P

STi = Subaru Tecnica International, Subaru's turning branch
UTEC = doesn't stand for anything I think, it's just the name of a piggyback ECU
XEDE = Same deal as the UTEC
IIRC = If I Remember Corectly
ECU = Engine/Electric Control Unit (derp!)
AVCS = Advanced Valve Control System (I think), it's Subaru's equivalent to V-TECH or VANOS, i.e. variable valve timing
MBC = Manual Boost Controler, simpel ball and spring valve for limiting boost
EBC = Electronic Boost Controler, sensor and solinoid controled valves for limiting boost
TBE = Turbo-Back Exhaust, i.e. replacing the exhaust from the trubo to the end
ESX = East Street Motorsports, I think the X came from the name of their 9 second drag car, the Easy Street wrX

Phew, that is a lot of acronyms (PTIALOA).

I know the UTEC is soon to come out. I'm not gonna go with the XEDE, just have been hearing a lot of bunk things about Shiv lately. I'm gonna stick with Nathan and TXS or Cobb. Cobb just released their tuning module for the AccessEcu or something along those lines that reflashes the ECU. Is that what you were talking about?

Dunno what AVCS is...?

What I'm curious about is if the EM solutions will actually need a MBC or will they use some other method built into the car to control the boost? I've never seen/installed a EBC to know how it works. That was my question I guess.

UTEC = User Tuned Engine Computer
ECU = Emissions Control Unit

Most people confuse the E with Engine or Electronic... but last time I checked it actually stood for Emissions. Not sure what it stands for on UTEC, but since it should cover the entire engine's function, I believe it's engine? Someone correct me if I'm wrong...

Good point on the ECU thing, it was originally for emissions only, but manufacturers have started cramming everything into that processor, from emissions to engine managment, to the goddamn radio stations. :lol: It really should simply be called the CPU.

UTEC is not standalone, it's a piggyback just like the XEDE is, and it can change most anything that the ECU uses for engine management, so I'd say "engine" is the correct "E".

Does the ECU function in a "stand-alone" or "piggyback" fashion?
Both. Stand-alone timing control, piggyback style fueling control.

Do you know if it needs a MBC to control the boost? Or is there some way it hooks into your lines to change it electronically? I'm still vague on that understanding.

And word on the CPU thing. Fucking ECU controls whether you have "one-click" on your power windows now... wtf does that have to do with your Engine/Emissions? NOTHING!

Usually, it is not just one CPU/ECU, but many, possibly in the same box, but often not. They all sit on the OBD2(On Board Diagnistics version 2) bus, so they can be managed from the one connector. It is actually really cool in some respects. On my A4, I can reprogram all sorts of stuff with the security module including opening and closing the windows/sunroof from the remote, etc...

Theoretically you can flash stuff through it as well if the manufacturer supports it. I can bring My notebook and OBD2 software if somebody wants to see it...

At minimum, you can see the codes your dealer doesn't want you to know about, and reset the ones you don't want him to know about... 8)

I like that re-set codes before you go in for warrinty work :wink:

I thought that it wired inline between the wastegate solinoid and the ECU so it can take over when necessary.

That would make sense to me. I was just looking at the UTEC stages on the TXS site and they had a MBC in the package along with the UTEC, so that's what made me question it.

... I think I was high at the time however, because now when I look back, I don't see it. Damn I'm tired :(
