An hour AT THE MOST. I wouldnt care about a backlog issue. I would wait for the part the stuff to come in, drop off my car and for this kind of fix pick it up the next day.
There's a reason why your a soon 2 be owner, and we're owners...

Having had a 1st allocation WRX (READ: the FIRST automatic black wagon in the state of illinois off the truck) we know first hand how their practices work. Get ready for a lot of the same, or just keep your skyline.

Got my car back from dealer yesterday. Took tech for a drive, he heard the det and said will send data he took from ECU along with his note on dets to SOA. We'll see what they say. I got a re-flashed ECU already and runing Cali. 91. Manager wasn't in to give me official word on power loss after re-flash(I asked him to check with SOA), but there is another thread with dyno results from re-flashed ECU on this forum.

Does anyone know what this fluttering/ticking is? I have the same thing 3-3.5k rpms but other then those rpms the engine sounds completely smooth.

I have only heard cars with bad detonation i do not know what mild detonation sounds like and everyone who has had det problems has had them between 4-4.5k.

Let me know if the reflash got rid of the flutter

Talked to the manages at subaru dealership, word form SOA rep was that "the power after re-flash should be exacly the same". So, no worries mates.

Also waiting on word form subaru about my det after re-flash. Hopefuly I'll hear something in next few days.

... no loss of power whatsoever, in fact you will have a more consistent engine.

Well it happens to me anywhere from 20% to 100% throttle just as long as I am accelerating in some way at 3k rpms i get that fluttering clicking noise. And it doesnt sound like pinging I have heard on other cars or like other people are describing there pinging.

I've also noticed this. Sounds similar to detonation, but it is not. It's also a lot more quiet. I think I've seen this discussion before but can't remember. Maybe something about an A/F sensor.

Does anyone have a clue/ideas?

My car does exactly the same thing. Some have guessed it's wastegate flutter. My car has actually pinged 4-5 times, and it is not a subtle, quiet sound at all. With the windows up, and the radio off (or in my case, not there), it will get your attention.

My car has run only 91 octane since I've bought it, usually from the same Texaco station by my house. Temps in Southern Arizona have been between 90 and 105 since I took delivery early last month, with humidity about 50%. The car now has 1500 miles. I kept under 4000 rpm for the first 500 miles, most of which was the drive back from Albuquerque where I bought it. Then I gave myself 500 rpm every 100 miles until 1000 miles. The car build date is 06/03, so it may or may not have been reflashed before I bought it. I have not had it reflashed.

The car has pinged 4-5 times, for a fraction of a second each time, between 3-4krpm, all since the 1000 mile mark. All the pings have been around town, at WOT or close to WOT, usually when flooring the throttle when the car was cruising at 3000 rpm or so. Happens when the car has been running for a long time, and is fully warmed up, but not all the time. It's usually not repeatable, and has happened at surprising times around town, not when I was out on a mountain road driving fast.

DO SOA fix the ping problem after you report the problem to them
or they simply replace all the ECU on the cars at the dealer's lot that's not sold.

if you have an older STi and report the problem, they will reflash your car.

cars that were already on the lot when the reflash became available probably were not reflashed, but any new cars delievered in the last couple months should have already been reflashed before they got to the dealers.

Finaly got an answer back from SOA through the service manager. The official word is "customer show drive their car for 5000 mile for computer to learn and adapt to customers driving style and then the detonation problem will go away." I asked for that to be sent to me in writing....

So, that's it.
Just quick background on my prob. I got dets after break in, at about 1.1k miles. Then got re-flash and still have dets. Running 91 Ca gas.

Drdray, so, does the reflash help reduce the pinging for you at all? It did for mine, even though there is STILL mild pinging, but much rarer now. BTW, let's see if the car learns or SOA learns (motor on the road)

Well, it did at first, but I'm getting a feeling it is getting worse. Or just occasionally. Some times it's worse, some times it's not so bad. I got mixed fillings on the issue right now. It almost went away when it got cool in the mornings, but then the other day it was around 70 and I heard it pretty loud and clear...... So, re-flash does help, but in my case it never completly fixed pings. BTW, I was told that SOA said that this pinging "shouldn't harm the engine at all" and that a quote! So, I'm going to drive it as if nothing is wrong with it, and if my motor does go bad........ I don't even want to think about it. I'd probably hurt some one if they say it's my fault..literally.

Is this with close to WOT? You had the windows up or down? I rely on my knocklink to tell me knocks... After the reflash, I have only seen the 1st and 2nd green lights light up ocassionally (versus the orange and red lights lighting up before) when close to WOTs. If I listen very carefully with the windows up/down, I can hear a very mild and 1/10-sec "brr" and that's it, when the green light(s) light up. I would not worry about it for now

Maybe you guys should try better quality brands of 91 octane, if higher octanes are not available. I know Texaco and Cheveron are junk gas brands for turbo cars. Try Shell, 76, and i heard Mobil Gas. The brands of gas really make a difference in Turbo cars, seriously. They may be the same octane rating, but you can really feel the difference between brands.

I FULLY agree and FULLY DISAGREE at the same time. In limited experience with gas in the Phoenix area and all points between their and Colorado I have found Amoco and Chevron to be the two BEST brands of gas to use with Shell and Mobil1 being the worst. This is from personal experience as well as others experience.

I do agree though that all 91 octanes are not created equal . A big portion of the quality of the fuels are what additives get added to them and the additives are different for each station type.

I also use gas stations that have a separate nozzle for premium; because if you have only 1 nozzle, someone before you may have used el cheapo gas and left 1/2 gallon or so of it in the hose... Not a good thing!
