aigochamaloh Posted March 29, 2011 Share Posted March 29, 2011 Subaru has developed a modification to the Engine Control Module software logic that will improve the performance of your vehicle’s emission control system. This software change will not adversely affect fuel economy or performance and only applies to models (Impreza, Forester, Legacy and Outback) equipped with a 2.5 Liter non-turbo engines. Vehicles with turbo or 6 cylinder engines are not included, nor are the Baja or Tribeca models. http://www.serviceprogramwvu31.com/ Link to comment Share on other sites More sharing options...
applesauce Posted March 31, 2011 Share Posted March 31, 2011 Any more info on this? Will the improved emissions control system make the car preform any better? Link to comment Share on other sites More sharing options...

zzztech13 Posted May 7, 2011 Share Posted May 7, 2011 Just wanted to say that I had this done on my 2.5i about 2 weeks ago. I have noticed a slight increase in my AVG MPG. For the first couple of days I noticed that the idle was kind of low, in the 400-500 RPM range and the idle felt kinda rough. My personal opinion is that the car feels like it has about 5-10 BHP less now. Thank GOD I have the paint matched eyelids to compensate for that!! Another note is that when using cruise control, if you try it accelerate using the cruise control stick (pushing up) it is more sluggish in responding. just my $.02 Link to comment Share on other sites More sharing options...
FLZ_Boy Posted May 11, 2011 Share Posted May 11, 2011 Hmmmm could explain why 08 Impreza feels thrashy and zippy compared to my 11 Legacy which feels docile. Link to comment Share on other sites More sharing options...
soloz2 Posted May 22, 2011 Share Posted May 22, 2011 Just had this done Friday, car felt fine driving it yesterday. A couple months ago Subaru flashed my ECU for a similar reason as I recall. Afterwards the car seemed to idle rougher on startup. This time it seems a bit better.

2006 SpecB Posted May 24, 2011 Share Posted May 24, 2011 Does this affect any Cobb maps? Do I need to re-load my Cobb stage 1??? Anyone know? Link to comment Share on other sites More sharing options...
applesauce Posted May 27, 2011 Share Posted May 27, 2011 I don't think this applies to your Spec B. Just non turbo 2.5i models. Link to comment Share on other sites More sharing options...
FLZ_Boy Posted June 8, 2011 Share Posted June 8, 2011 So I finally got a notice from Subaru regarding the ECU reprograming for my 2008 Impreza. California owners should note this is a requirement from CARB. Here is the California Owners excerpt: CALIFORNIA REGISTERED OWNERS The California Air Resources Board requires that emission related campaigns be completed prior to California's vehicle registration renewal process; without this repair, you will not be able to register your vehicle during your next annual registration. Upon completion of this campaign, your California dealer will complete and provide you a "Proof of Correction Certificate." If required, present the certificate to the California Department of Motor Vehicles (the "DMV") when renewing your California registration as proof of campaign completion. If the DMV does not request the certificate, we recommend that you keep it for your records. In addition, the State of California requires that every vehicle must pass an emission test (SMOG Check) every two years and before it is sold. Without the service we are providing at no charge, your vehicle may not pass this test. Link to comment Share on other sites More sharing options...

California is one of the states that has stricter emission laws since they require naturally aspirated vehicles to be PZEV certified. So why does the "State of California" require an emission test every two years instead of every year? Link to comment Share on other sites More sharing options...

So why does the "State of California" require an emission test every two years instead of every year? If you drive manual transmission NA Subies in California, you don't get a PZEV sticker, they are considered LEV2 (or somthing like that). My 08 Impreza 2.5i 5-Speed Manual and 11 Legacy 2.5i 6-Speed Maunal were both bought in California without the PZEV sticker. Hence, you can tell if a 2.5i is a manual or automatic (autos get PZEV sticker) by whether the trunk lid has a PZEV sticker slapped on. California Air Resource Board is really just a bunch government workers just trying to survive on tossing as many regulations they can to justify their existence. I'm glad California is having a budget crisis, all the "flower" people can see the axe all I care. Link to comment Share on other sites More sharing options...

Made people ask me if it was a hybrid when I was autocrossing, and I'd just answer yes. They didn't like the fact that a "hybrid" was going around faster than them.

FLZ_Boy Posted June 9, 2011 Share Posted June 9, 2011 ^This only applies to the new generation cars, 5th Generation Legacy. However, I just looked up the 08 Impreza, apparently both Manual and Autos don't get the PZEV badge. In any case, I don't get the cool leaf badge for either cars. I did see your video on Streets of Willow (CCW), I think that was the time you were runing around ~1:42 stock back in 2008. I took my 08 Impreza stock and ran 1:42 stock back in March of 2009 (CW) old configuration. The 08 Impreza without a rear swaybar had ALOT of body roll.

aigochamaloh Posted June 9, 2011 Author Share Posted June 9, 2011 Hmm, the new Outbacks have the PZEV badge. I see those around. I don't recall seeing a 6th gen Legacy 2.5i having one though, you're right. I ran a 1:40 stock in the Legacy on SOW. Tons and tons of body roll.

RabidWombat Posted June 9, 2011 Share Posted June 9, 2011 Just had this done on my wife's 08 Impreza. The car seems much smoother at idle, but I don't drive it daily so I can't say for certain. Link to comment Share on other sites More sharing options...
aigochamaloh Posted June 29, 2011 Author Share Posted June 29, 2011 Just got the notice yesterday, had it done today. Stumbles at idle, just like right after the other reflash a year back. Stalled on me a couple times today though. This is the worst I've had it stumble when approaching lights and putting the clutch in. Service adviser also scratched my door with my keys when he was trying to get in the car to read the mileage. Only two times has the car gone into the dealership (for each reflash), and both times has come out with a new scratch or two. Absolutely lovely. I'm driving the car around like I stole it so it learns my foot again, and hopefully the stumbling clears up like it did last time. Link to comment Share on other sites More sharing options...
soloz2 Posted June 29, 2011 Share Posted June 29, 2011 Mine will start and idle rough for 30sec or so, but once it's warm it's fine.

TX_Andrew Posted August 29, 2011 Share Posted August 29, 2011 Car has also been stalling during start up. Had Subaru fix the issue and the car stopped stalling, however, it still would idle lower than 500 rpms. Then I had some more work done in which the car lost batter power (evident by radio stations and clock settings were back to default). Now the car is stalling all over again. Going back to Subaru to see if I can get them to remove the update. Link to comment Share on other sites More sharing options...

Subies4Life Posted September 10, 2011 Share Posted September 10, 2011 Is this software flash even worth getting? I also got a letter but i'm hesitant to take it in. Link to comment Share on other sites More sharing options...

It may be - especially if you sell your car and it ends up in California or somewhere else where it's required. Link to comment Share on other sites More sharing options...
