OuttaSpec Posted May 4, 2009 Share Posted May 4, 2009 I simply told the dealer that I had the stutter/acceleration problem. They agreed it was doing "something". Then, when the folks on this site said Subaru released a flash, I took it back. I printed out these pages as proof- but they didn't need it. They found the service bulletin, downloaded the flash from the Subaru website, did it and I've never looked back. White Allen Subaru in Dayton, OH did it. It's been fine ever since.

stewartg Posted May 5, 2009 Author Share Posted May 5, 2009 i think the sb is for 07/08 manual lgt's and spec's only, people have had different results with the dealer reflash including lower power, worse gas mileage and even the stutter coming back. 05/06 also had a similar non-functional reflash. the two things you can do is drive the car in a manner which avoids wot at 2500-3000 rpm, or get a stage 1 or 2 ecu flash from a tuner.

Crave35 Posted May 5, 2009 Share Posted May 5, 2009 i guess i will try to bring it to the dealer and see what happens....it seems to be better when its cold but then again it fluxuates so much that its hard to determine. Since the plug change i think the computer is starting to recognize better performance so it is smoother but like i said it just did it today really bad....mf..I NEED REFLASH Link to comment Share on other sites More sharing options...

I have an 07 GT manual, and find that the car runs a lot smoother when it is warm as opposed to cold. The dealer says I have the most current software on the ECU, they reflased it sometime last year. I get the stutter now and then, but much more in the cold weather. Link to comment Share on other sites More sharing options...
jp233 Posted May 6, 2009 Share Posted May 6, 2009 what reflash "was just posted" for 05-06 GT/XT's ???? I am still being told "there is no reflash for your 2006 Legacy GT". stutter still sucks AZZ, 100% OEM car, 0% aftermarket, and it just turned over 30,000 miles (!). Is even prevalent in high gear when you go WFO, in a highway roll-on. am going to borrow an AccessPort and re-flash myself after the standard Subaru warranty goes out. (that is, in case Subaru can't remedy this problem on their own, which I don't have confidence that they can/will) :mad: Link to comment Share on other sites More sharing options...
Crave35 Posted May 6, 2009 Share Posted May 6, 2009 the interesting thing is that i had no problem for 48000 but at 48000 my turbo blew up because of the uppipe that was on didnt have enough back pressure for the turbo. Subaru replaced the engine and turbo and now 20000 after that i get a stutter...does this possibly mean that the turbos are bad??? Link to comment Share on other sites More sharing options...

Well this leaves the question, has anyone tried comparing our stock turbo with an after market one? Was the same tune used for the after market turbo as it was used on the OEM turbo? Were the results the same? If the results are the same, then could it be how the car is mapped? How about the way the car breathes? Too many variables.

How about the way the car breathes? Too many variables. After market turbo on stock map = major fail, so I doubt you are going to find that comparison around here. It is the sub-optimal tuning, not the turbos. I don't think I have heard of stutter complaints from anyone stage 1 or 2. I reset my ecu at the track 2 weeks ago and only once felt any sign of hesitation the entire day. I haven't driven the car since, but I usually drive pretty sane on the street and it's not much of an issue for me. I will be going stage 2 this month before I get back to the track and end this crap once and for all. The subaru flash for 07/08 is a joke, it reduces the power output, makes the fuel economy very poor and the hesitation can still be felt (albeit less frequently). I have come to the conclusion to not hold my breath waiting for them. Atleast I have notified the dealer that I still have the problem even after being flashed, so I would be able to get the fix (if one ever came out) after the warranty expires, but not after going stage 2 and hopefully it wouldn't be needed then.

I've been driving pretty easy through the first 1k and havent noticed anything yet myself. I have an '09 LGT. The hesitation is felt around 3K to 3.5K. Albeit slight. During the first 1K, I drove the car like a grandma and never left the Intelligent map in the SI drive config. After 1050 mi, I opened the car up on S# mode and did not feel a stutter until I reached 2K mi. It does not happen often. It happens randomly at best. However I have noticed on colder mornings, the car stutters more in that RPM range. And yes, I do warm my car up first before driving. Especially on warmer days. I never drive until I give the engine enough time to circulate the oil, knowing how badly our cars starve for oil. Oof! Link to comment Share on other sites More sharing options...

Crave35 Posted May 20, 2009 Share Posted May 20, 2009 i went to dealer they said that they wanted 90 dollar estimate fee but if they found it was a part that would be warrantied they would fix it and or reflash for up to 80000 and then give the 90 back. i convinced the service manager to come for a ride and when we went for it the car did nothing and ran perfect like it was brand new..figures. wat should i do now Link to comment Share on other sites More sharing options...

Hanslo Posted July 1, 2009 Share Posted July 1, 2009 Originally posted by smokinduc ...Somewhere on these boards is a TSB. I just printed a copy of it and brought it with me to the service manager. My computer as reflashed no questions asked... Worked for me too. I got the reflash on June 18th and so far so good. It looks like my gas mileage has gone up about 1-2 mpg and I don't think I have lost any power, if so its subtle. It feels like it did when I first drove it off the lot. I'm really glad I did this. I've had the stutter for almost two years now and it felt like it was slowly getting worse. I really, really hope this sticks. Hanslo Link to comment Share on other sites More sharing options...
Crave35 Posted July 1, 2009 Share Posted July 1, 2009 ur legacy is an 07 and the reflash i have of the stutter is only for 07s and 08s..mine is an 06 does this at all matter?? Link to comment Share on other sites More sharing options...
Windy Road Posted July 2, 2009 Share Posted July 2, 2009 I have the stutter in my 09 GT, it happened today right around 2500 rpm. It happened a few times before, its hard to recreate it. So I'm guessing I'm going to have to swing by the dealer and get it reflashed. 276hp/347tq On a DynoJet Dyno Video - Had a big lean spot as you can tell in the second pull Link to comment Share on other sites More sharing options...

Yeah, I guess it does matter. Hopefully your dealer will know about the reflashes and whether or not one exists for the '05 & '06. Possibly it might help if you have the pack file# from the 07/08 TSB they can find a pack file# for yours (maybe..?). Good luck, Hanslo Link to comment Share on other sites More sharing options...

clarkwgriswold Posted July 8, 2009 Share Posted July 8, 2009 Don't know which part caused the stutter to go away because I did all three at the same time. I replaced the up and hollowed out the 2nd cat. and installed a turbo inlet hose and the stutter is gone. Don't know if it will help everyone but it worked for me.
