Default det after reflash

it is back. started hearing it last week - gave it another week just to make sure.

the SOA rep will be at the dealership on wednesday and so will i with a powered down, pinging, SOA reflashed sti.

5200 miles on vehicle ~3000 since reflash

94 octane, A/C on, 100 degrees, 3500-4500 rpm..., pings under acceleration

ever play pachinko?

this will be twice into the dealership for the same problem within the warranty period. i really hope they can fix it, as i hate to have to fall back on the lemmon law if the 3rd try is unsuccessful.

Dude, that sucks!

I had my STi all summer...since late may... through 100 degree track days, 100 degree autocrosses were the car just gets heat soaked to hell as I wait in line for my turn with the engine running and A/C at full blast and no ping what so ever, original ECU!

The lowest I had was 93 octane in MI. In canada I can get Sunoco 94 anywhere.

I'm curious if this is related to a batch of cars or anything like that...???

...oh, I'm at 5000 kms...3100 miles.

i think the build date is at on the door panel..

seems like Cali and AZ are the worst in terms of Pinging.

"~"3000, is that bad?

~350 a week commuting.

250 extra miles to PHX for a certain dyno run..., run into town to get scooby snacks (20 miles each way), etc.

i'll get the service slip and post exact miles if it helps.

has ANYONE else made ANY progress on getting a dyno comparison. my email to porter offering to send my ECU went unanswered - FOR SOME REASON.

c'mon subie, make the numbers from your extensive research into the reflash available! that is, unless there is something to hide.

MUWAHAHAHAHAH!!!!!

i reset the ECU on saturday by disconnecting the battery for a few hours. we'll see what happens. no ping since reseting the ECU - ~70 miles since reset.

maybe the cool mornings (60s-70s) and the hot afternoons (100s) are throwing the thing off?


if one screws up it is typically a training issue, if one continues to screw up it may be a learning disability.



will this ECU ever learn?

I think your local refinery is passing off 91 as 93, thinking no one will know the difference.

I'm curious whether the lemon law will apply since the owner's manual clearly states this is normal behavior for the car. I imagine the statement in chapter 7 of the manual will make it hard to make a claim of defect based on pinging.

I know you have concerns about the long-term effects and they are certainly valid, but it appears the car is operating within its design specifications.

I'm not saying I think you should roll over and play dead if you aren't happy, but this irritating characteristic of the car might just be normal.

i hear ya' killer, but they have already written it up once "pinging under acceleration" and tried to fix it - seems somewhat counter to your argument of FAD (functioning as designed) - why try to fix something that is FAD?

spoke with the SOA rep this morning, for some reason he feels i should have been running 91 octane. he seemed kinda suprised when i said that after 2 weeks of 91 octane on the reflash it was pinging like a beeotch. then i told him that i switched to 93/94 octane (no they do not sell it in AZ, but they do sell 100 octane race gas at 76 stations) is was OK for ~2 weeks, but it now pings worse than ever.

i now get det on cool mornings (72 this morning), A/C on, A/C off, hot/humid, cool/dry - you name the condition and i get det.

all i need to do to reproduce it now, is to floor it when the rpms are at ~3000 - PRIIIIINNNNNKKKKK.

it is really, really bad. mebee i should run 100 octane at 4.50 a gallon.

i'm somewhat resigned to the situation and told the SOA rep that the only thing i want is an STi that does not ping CONSTANTLY.

if that means a drop in HP/TQ i don't care and will sign a waiver or whatever they want. i also added that to make this repeat customer "happy" i really wanted an STi that did not ping CONSTANTLY on 91 octane - that would be too cool!

i hope it is just MY car and conditions. if not, subie may want to add some additional resources to getting it figured out.

Just to add to the discussion: I had my car reflashed at 3400 miles. Got the car back last week and everything was okay--no pinging.

Just today, about 300 miles later, I got pinging under WOT in first gear. Not nearly as bad as before, but definitely there. Same place--about 4500RPM. Add this to the very noticible loss in power after the reflash, and I am not amused.

HOLY COW!!!!!!!!!

Mike, I have been so busy, I havent been following this thread!

OK, to sum up, you are now on the 2nd re-flash and pinging worse than before?

Let me hook you up, there is a guy that will deliver 55 gallons of Sunoco GT Plus 109 unleaded to your door. Under $300 for the first barrel, then $265 for every refill.

This is what I have been doing since day one of pinging on May 30th.

I plan to keep this up until ECUTEK has the BIN file to tune our ECU's.

Shoot me an email and let me know what you think!

BTW, just clicked over 9k miles and now run Amsoil full synthetic.

You can do this, but at what cost?

The pinging could smoke a piston while the ECU is learning!

Good question!

After I set the world on fire with the "un-usable" dyno results, PORTER came to the rescue with the Dyno Pack offers.

"Have you seen PORTER"

I have a business trip in Oct in which I may have to stop by Atlanta on my return trip. If I do, I plan on dropping in on Porter!

Crapper... I just started opening mine up (still at around 1100 miles)... audible pinging at around 4k.

Oh, and 300 bucks for 55 gallons equals 5.45 per gallon and 265 brings it down to 4.81. There's a Mobile station in Awhatukee that sells Trick 101 for 3.99 a gallon. It's listed as 101 but thats with the (R+M)/2 method. Using just the Research grad it's around 107 octane (which is probably what the Sunoco is rated in). Stupid Arizona gas and weather.

I just had the reflash... It pinged only once right after me picking my car up. But, now (a week into it), I cannot get it to ping no matter how hard I drive! (same tank of gas as before reflash).

For those who got the reflash, does your car start pinging back right away, or after a while (how long before it starts pinging back)?!?

I heard it ping righ after pick up, but later on it sort of went away. About 2 weeks later I was able to make it ping again, not as loud and often but still there. Going back to dealership next week for test drive and see what's next. Also asked to check with SOA for the official word on the power loss after re-flash. Like they going to tell, but who knows.

drdray, great... please keep us posted... BTW, what dealership did you go to? I went to Maita...

Edit: Also, what gas are you running? I am running toluene mix with effective octane of ~93.

Hey Fhqwhgrass,

Can you tell me the cross streets of that gas station. I'd like to check it out the next time I'm in Phoenix. I went to high school in Awhatukee so I know the area pretty well.

I go to Maita, they already know me I think by name . but probaly go when they see me.

Runing 91 from 76, I kind of go between that and Chevron. I think scooby likes 76 more, but I can't support that with any proof. It just feels kind of happy with 76

Shiv will be dynoing my car (I'm on my first reflash) alongside some other STi's. There may even be an opportunity to put an unflashed ECU in my car to get an apples-to-apples comparison--although I don't know if this will work (ECU locking, learning, etc.) or not. But if there are five unflashed STi's within 5% of each other and mine is down by 15%, then you know something's up.

Hey Darwood,

The gas station is on Chandler Blvd, about 2 miles west of the 10 freeway. It's on the north side of the road and there's a pump with a white handle (only 1 pump though, so you gotta go to the right one). I can't remember the exact cross-street... it's a little bit west of Hooters if that's any help
