Deer Killer Posted July 14, 2005 Share Posted July 14, 2005 This is not an ECU issue. I had a catless uppie installed, & studdering is gone. Obviously it has to do with the restriction being to close to the turbo charger. Unless, yor're in California where they check for smog emissions, removing this pre-cat isn't illegal.I still have plenty after the uppipe. Ask SOA. edit - oh, and wrong on all counts, is that why you used bold? Link to comment Share on other sites More sharing options...
melayout Posted July 14, 2005 Share Posted July 14, 2005 Deer Killer - Did you try resetting your ECU ? Maybe it's current maps still exhibit hestitation because the pre-cat induced it, now when you reset the ECU without the upipe cat, would it not learn to hesitate ?

I could actually datalog it to prove what it is, but I'd have to go back to stock map to be able to do it easier. Maybe I will. It's just not something I have the bandwidth to take up at the moment. It's much to quick to be a boost issue, it has to be OL/CL ignition timing. Link to comment Share on other sites More sharing options...
dark_rex Posted July 14, 2005 Share Posted July 14, 2005 removing or alterring factory emission control systems is a FEDERAL offense, and almost certainly violates some of your state level laws as well. Don't tamper with this and pretend you're within the law. Some states are tougher with enforcement than others, but that doesn't make it legal. dR Link to comment Share on other sites More sharing options...

Why is it that everyone with an ECU mod reports this as being gone, and Subaru has now released an ECU fix for stud-tering? This is the first report of an UP fixing it that I've heard, and with the millions of UPs out there, I would think that we would have had that conclusion a year ago.

firedawgs Posted July 14, 2005 Share Posted July 14, 2005 I have an headers, uppipe, and downpipe. I have not seen or felt any improvement in my engine. Updated my vBGarage: Link to comment Share on other sites More sharing options...
mwiener2 Posted July 14, 2005 Share Posted July 14, 2005 took mine into the dealer today. They couldn't duplicate it, so i drove them around in mine and showed them. Then told them to pick any 2005 2.5 turbo off the lot, 5EAT or 5MT and I'll duplicate it on that too. So they did. And I did. And now they're looking into finding that TSB. They called the SOA tech line, but the tech line hasn't called them back yet.

GetAwayDriver Posted July 15, 2005 Share Posted July 15, 2005 I'm going to swing by my dealership tomorrow... and I am supposed to drive cross country this weekend. Great timing but good to hear there is a fix. Thanks for the post. Link to comment Share on other sites More sharing options...
Opie Posted July 15, 2005 Author Share Posted July 15, 2005 And now they're looking into finding that TSB. They called the SOA tech line, but the tech line hasn't called them back yet. There is no TSB as of yet, but the Tech Line is aware of the issue and the reflash. Here's a little more info I drummed up on ECM (Electronic Control Module)Reflashes: Logic Change #1 (U6) Federal Emission Specification Only - 05MY Legacy 2.5L M/T & 05MY Outback 2.5L M/T Conditions: 1) - P1160 (RETURN SPRING FAILURE), 2) - P2097 (POST CATALYST FUEL TRIM SYSTEM TOO RICH BANK 1), 3) - Cruise Control Intermittently Shuts Off, 4) Surging during moderate acceleration.

I'm just interested to see if any dealership will actually fix this. So far none of the ones I have talked to know what I'm talking about. They are treating me as if this is the first time they have ever heard of the problem and there is no fix. Why aren't the dealerships aware of this? Did they not get the same email that Opie got? _________________________________________ “Cleanliness becomes more important as godliness becomes more unlikely.” O C D E T A I L S .

melayout Posted July 15, 2005 Share Posted July 15, 2005 Opie, looking at the Logic Changes for the ECM, it looks like the MY05 Legacy 5EAT is not affected but only the MY05 Legacy M/T. Is that correct ? I keed I keeed Link to comment Share on other sites More sharing options...
OCDetails Posted July 15, 2005 Share Posted July 15, 2005 I did it again yesterday too. It's still there.... It's not as bad as it was before I did it the first time, but there isn't any difference from before I did it the second time. The reflash is the only solution I think. _________________________________________ “Cleanliness becomes more important as godliness becomes more unlikely.” O C D E T A I L S .

Is that correct ? I noticed that as well, but I think it's a typo...because none of the turbo models get the 4EAT and it is definitly a Turbo car reflash (I can tell be the ECM CID's) Link to comment Share on other sites More sharing options...

Opie Posted July 15, 2005 Author Share Posted July 15, 2005 Sweet, were you experiencing the hesitation and did you get your ECM reflashed ? Thanks, again. I can get mine to do it "sometimes", but it's very rare, and not easily reproduced. I haven't started the procedure to get mine flashed yet because I've been driving the wife's car due to the rain and construction on my commute, but I will do it soon.

I got the same thing from my dealer when I mentioned it but that was before I got the info from this thread. Now that I know that SOA is aware, I'll be taking it back as soon as I can to try again.

RoundBoy Posted July 15, 2005 Share Posted July 15, 2005 The TCM module reflash -- is that the same one that was out a while ago for people running in a lower gear then they should be in for a long time ? I.E. it prevented you from driving around in 1st all day... Link to comment Share on other sites More sharing options...
Glenn Posted July 15, 2005 Share Posted July 15, 2005 Oh really? Please back that statement up. <----- PGT has smog check coming up in VA soon In any state where there is a smog check if your vehicle has 50K or higher you are exempt from having anything more than 1 required cat, only exception is diesel where not cat is required.
