Let us know your mods and your impressions. It will be 2-4 weeks before I can send mine.

BTW, did you get any "special options"? I will be installing a Stealthback this week and will be welcoming myself to the CEL world because of it. Since the normal CEL fix doesn't work on 04s, I am presuming they can tailor the ECU to fix this like they can with the 02-03 models.

Yup,
I asked for the rear O2 CEL fix and they said no problem, they already have it fingered for the '04s.

I'm still working on picking a TBE. Leaning towards APS. I think I will jump right to stage 2, 93octane . 93 is easy to get here in Texas, and my wife's XT (stock for now )will most likely be the cross-country vehicle.

I just ordered mine. I am buying an ECU and having it flashed to stage 1. Figured it would be nice to have a pristine stock ECU for reference. BTW, the price went up on the 2004 ECUs a bit. Cobb didn't have the ECUs in stock, so now I wait...

For reference? Wow that's a lot of $ to throw down on an extra ECU. Congrats on the purchase-I can't wait!

COBB got it, reflashed it, and shipped it. I get it Thursday morning and I'll have it in by lunch, hehe.

What I meant is that I can always go back to stock in 20 minutes if I need to or want to. I plan to eventually do a turbo back as well--no down time. And if the Access thing ever comes out, I will have two ECU's--one to play with and one that always works.

I figure in the end the cost of the ECU will only be about 15%-20% of the mods I am planning.

brahmzy:

(man our handles are similar)

Let us know how things go. Are you getting stage 2 (inferred from your requested CEL removal)?

Anyone else out there getting stage 1 on a 2004?

Well, I got it in the car an hour ago and WOW! I'm very impressed. I've only driven it 11 miles so I think it's got some more learnin' ta do, COBB said it'd take a day or two to do wat it needs to do. But I'm happy with it NOW.
The wierdest thing is the smoothness. I know everybody keeps sayin' this but it's true. Things even SOUND smoother. My TXS t-back sounds awesome now! Even the turbo sounds better!
Lag is improved tremendously. I accidentally hit the 1st gear rev limiter (something I've never done before) because it rips through 1st so quick. In fact it rips through 2nd pretty quick too. When driving along with traffic, in 3rd or 4th gear, so much more power is on tap, part throttle. It is very enjoyable to drive-I remember when the car was stock, the lag kinda wears on you after a while in daily traffic-not now.
I have yet to get the car on the highway but I can tell it'll be fun.

Now some questions.

To those of you with the Stage 2 91 AccessECU at 5,000 ft. or above, what is your pressure reading?

And, I have a TXS short-ram (ya know, the one TXS swears won't mess with the MAF) and I'm wondering if I should take it off and put the stocker back on. COBB hasn't had enough experience with this intake yet to give me a solid suggestion. And TXS won't tell me either because it's not their engine management. I don't have an A/F guage and don't plan on getting one. So, should I leave on the intake? Anybody been in my exact situation with an A/F guage or a meter of some sort?

Thanks!!

Another VERY satisfied ACCESS ECU owner!!!!!

Thanks for getting back with the report. Sounds like money well spent. I am getting the week after next off so I can send in my ECU. The wife thinks it's so they can "fix my CEL problem" (half truth) from a buddy of mine that "hooked me up with some straight pipe" (lie, unless people hook you up with a Stealthback) so I guess I will in for some grin time! Thanks again and if you have any more to report in the next few days, please do so.

Brahmzy, we should give each other rides tomorrow after work - me in your modded WRX, and you in my STi. Email me.

WOAH!!! I've just been drivin' my car (back home from work) and this things has gotten a WHOLE lot faster. I've got 53 miles on the new ECU now. I can't believe the difference!! The car just pulls hard through all gears and it is very hard not to hit the rev-limiter in 1st.
The reflash has totally transformed this car. I don't think I've ever seen one particular mod make this much difference to a car. for under $400.00!!! Of course it took $1,300 before this to 'prep' the car with the t-back and uppipe. And basically I think that's all those mods are. They pave the way or 'prep' the car for better engine management (more boost/better map). I guess I'm stating the obvious here.
When I got my uppipe/turboback in, I was like 'Those helped it out a bit...' but this reflash as FAR more of a jump than either one of those.

Thanks COBB again for a wonderful product!!!

Did you get/use the little wastegate bleed valve thingy? I have heard varying success/failure here about it and wanted to see if they still give it out, or what your impressions are if you used it.

Can you describe your boost level in all your gears too? I am mainly interested in starting RPM, full boost RPM, max boost PSI/mPa, and where it starts to fade off, if at all? These can be rough, I know it is a PITA to watch the guage and the tach at the same time.

Aug 11th my ECU goes to Cobb and I am this anxious about it:

Geez that's a long wait-you're gonna be dying!!! Make sure you do at least 2nd day AM ups to and fro-it was cheap. I'lll try and grab some o' that info. You won't regret this mod. Keep in mind, I never had an MBC or anything like it before so I'm probably experiencing something most of you have already experienced, but much safer than an MBC. Smoother too I'm sure.

Yeah, it is a long wait. I figure if I keep nagging you with trivial questions, it will make the time go faster! Funny how you can be jealous of someone 2000 miles away and you will be getting the same thing in 2 weeks. Thanks for the reports, your info is reinforcing my decision. Tick, Tock.....more time gone!

One thing I've been noticing with my new reflash is, really wierd actually. I think I like this feature-I'm getting used to it. When I'm driving (normal or hard) and I shift, they engine keeps the rpms revved for about 1/2-1 second longer before I start to see them drop.
In other words , let's say I'm in 2nd gear, rev to 4000rpm, push in clutch to grab 3rd, the rpms stay at 4000rpm for like a half second longer or something before they start to drop-and by that time I've grabbed 3rd and am engaging the clutch only with less rev-match required. Does this make sense? It's like I doubled the weight of my flywheel or something, without any of the negatives. I dono-hard to explain. Maybe this is due to the additional boost affecting something mechanical?
Anybody else experience this? Like I said, I don't think this is bad, I like it actually. Just have to relearn the rev-matching points from stock.

Doesn't that make it take longer to shift? The flywheel is already super heavy and the 1-2 shift already takes forever. Are you sure it's really holding rpms longer?

Yeah, I'm sure. I don't think it takes longer to shift, 'course I could be smokin'. It's really hard to explain what's goin' on.
