Okay.... member on here that can chip the ej20g ecu... <cough><cough>...

Is the 550/tdo5 chip ready yet? Not that I know who you are...<uurohhhhhbbb><ehhhhhemmmm> ... something in my throat

..... oh yea... to stay on topic... um... ok the legacy ss that I dont own has a new chip option. sounds like something for somebody with a legacy to try.

I like this chip because they said it keeps all factory safeguards like knock control and boost cut should you get bad gas but brings the boost upto 14 or 17lbs (your choice via jumper or external switch).

I think I may go this route and use a leg turbo ecu & this chip with my 95 impreza that I am putting a ej20 turbo in, the main drawback was they are only set for 7lbs boost and the fuel cut was about 12 so you need to use a boost controller and fuel cut defender.

there chip raises fuel cut and sets your boost, is that what you were talking about?

I can buy a Z4 Ej20G ECU and a set of JDM coils for less than the cost of their "chip". Plus, unless you've already got DOHC heads this chip is a waste of money. Everyone knows that the liability of the Ej22T cars is the heads.

That seems familiar. Wasn't it a 2 door GC that was really light with a rotated turbo?


Oh I just bought a 91 turbo legacy the other day for $200. I'm kicking around ideas of what to do with it still.

hook me up then, i wouldnt call it a waste of money especially since it's way cheaper than any odb2 tune and chip. some people cant or dont want to change there heads but are looking for some decent power gains and this will work very well for them, for a very fair price.

So don't call it a waste of money. Go do your own thing. It's a free world. But I definitely laugh when you say that some people don't want to change their heads but are looking for some decent power gains. I guess that's open to interpretation, but for what I would consider "some decent power gains" you will need an intercooler, a bigger turbo and injectors at a bare minimum. Even if you go shop frugally for that stuff you are going to spend somewhere around $600 or $700 for all that stuff. For that kind of money I can get an Ej20G longblock with turbo, injectors and intercooler and drop it in there.

Oh wait, I already did that. It made 170whp versus the 95whp the car put out stock. That was on the stock EJ22T ECU. Didn't change a thing. I just let it do it's own thing. Oh, and that was a TD04. I even decided not to bother putting in the Z4 ECU because it wouldn't have given me a whole lot more. You can do the math, but stock 2.0L USDM WRX's put down 155whp on this particular dyno.

I've owned 6 SS's and touring wagons. I've swapped engines. I've swapped just heads. I've installed AWIC's and AAIC's. I've installed td04's, td05's, vf8's and vf28's on these cars. They all ran well on the stock ECU with just little tweaks like a FCD and MBC. If you are gonna go farther than that, I personally want to be able to control everything and would spend the $1000 or more to get a standalone. But maybe that's just me.

You are free to do what you want with your own car. If you think this is the next great solution, do it with your car and post results. Just please quit spamming us in multiple threads with links to these people. This thread is the appropriate place for it. The rest of it just makes it look like you work for them and are engaged in unauthorized vending on this site.

i've put in a td04, 06i/c, tb titanium exhaust,custom cai intake and a set of 17's for less then $600, with the addition of the chip i should be looking at around 800$ total and 260 at the crank, all while on a budget with kids. used parts for these are cheap(as you should know) and i can put out some decent numbers with the setup.

i'm not saying your ideas/setup's are ****ty, but not everyone goes the same route. and until i pull my first engine and decide what i will do to it, i'm happy with what it's doing. it keeps it stockish as well without mbc's or fcd's.

i'm not trying to sell anybody ****, i was just giving people a heads up to what's now available. you have your opinions, i have mine

You are going to have to come back here with a dynosheet to back up that 260chp claim. While that's not some atmospheric number it's high enough up there that if you're gonna call it you've got to proove it, especially given the heads you are using.

i'm up for that, but it'll take a few months before i grab the chip and have it dynoed. now you probably know these cars alot better than i do, but were only talking about 100hp over stock and we have-

td04 over vf11
intercooler over nothing
custom c.a.i 3" i.d over restrictive stock unit
4" k&n cone
3" catless perrin div over small catted stock
3" titanium cat back w/ high flow custom tit muffler
jecs maf
bov
chip- 8.7 psi to 17 psi and better power curve
440's and a walbro will be added when the chip goes in

just over a 1000cdn, call it 800 u.s

if that setup cant give me a 100 hp then i'll blow it up so i can build a new one

17psi is going to be way outside of the td04's efficiency range when you put it against 2.2l. That's 10% more displacement than it was intended for and that makes a big difference. You might want to look at some boost maps and run some numbers with pressure ratios before you commit to that much boost. That's likely to generate a bunch of extra heat and little if any extra power over what it would do it you ran it down closer to 1 bar.

Hmmm, a 2.2 engine with heads that flow 20%+ less than a 2.0 will be able to flow 10% more air given the same boost? Maybe you need to check your numbers too. It just seems that you're a little quick to put down others that don't think the same thing as you.

Where have I put him down? Where did I call him names? I disagreed with him. You are the only one who has come in here and made it personal instead of a discussion about matters technical. My skepticism has nothing to do with this guy. It has everything to do with personal experience.

As for your other comments? They are irrelevant. Both EJ22T heads and EJ205 heads flow enough to allow the td04 to hit it's limit. The displacement of the Ej22 is very relevant. But feel free to proove ME wrong since you've made this personal.

What dyno? Baseline numbers? Correction factor? Without more information that chart doesn't mean much.

ps. I'll even give you guys some real data to review. This is the actual dyno information for the car in question. You will notice that it doesn't hold 17psi past 3200 rpm. This is because the turbo can't keep up. They've got to start tapering it that early to keep if from getting outside it's efficiency range and getting too hot.

http://www.revtronix.com/downloads/dyno/Stage2run2.Txt

At the same time it does suggest that the guy doing these chips has a certain idea about how to tune properly. Keep in mind I never said anything against the tuner or his skills. I only said that I didn't think his product offered enough performance gains for me to consider it worthwhile.

Again it goes back to definitions. When someone says "I'm going to run it at 17psi" most people around here assume you are going to run that up into the area where the turbo engines make their real power (5000+rpms). Running a car that peaks boost at 17psi @3200rpms and quickly tapers to 13.5psi at readline isn't what I would personally call "running 17psi". I call that running .9 bar.

Not trying to start anything, my comment was just a comment that's all. To an observer of this thread it sure seemed like you're trying to piss him off but if you say you're not thats fine I guess.

Regardless, wouldn't you expect the TD04 to do better than a VF11? It can flow approx. 10% more. That would put it around 16.5 psi up top instead of 13.5. Of course there are other factors but that's just a ballpark number.
