Default Custom tuning of ECU vs. Warranty

Hello everyone, I've got a warranty related question that I hope someone has the answer to. I'd like to get my 2007 STi tuned specifically for my SPT Intake. I'm having problems with it right now (those details are in another post). My car is still within its 3yr / 36K warranty period. If I get a custom tuner shop to dyno tune my car to better handle the intake, will that cause warranty issues down the road? For instance, let say 5000 miles down the road, something goes wrong with my turbo, or there is misfiring, will Subaru have the authority to deny my claim? Or, will they even know that the car has been tuned? Thoughts, comments, answers...all welcome!

Yes, they can decline coverage.

You should not expect SOA to cover your powertrain after you have re-engineered your powertrain control module. Ask your tuner if he will cover powertrain failure repairs rejected by SOA.

I read your other post here: http://forums.nasioc.com/forums/show....php?t=1648936

My take on things: Something may be going wrong with your car. Do not have it tuned, or make any mods that may jeopardize your warranty. As you had the dealer install the spt intake and catback, there may be a warranty on them also. I would call SOA to see what they have to say.

I've never heard of a tuner doing such a thing.

Honest thing to do- pay to have it fixed.
Not honest thing to do- revert back to stock and see if problem presists, if it does then try to issue a claim.

One of my local dealerships actually told me he can't help me unless I revert back to stock. (I was having a stumbling issue between shifts on my 07 STI)

if u get the cobb access port and save the Oem flash u can still get warranty work done. What u have to do is if something comes wrong turbo, misfire whatever. what u do is reinstall the oem flash back in to the ecu. and u will be fine. subaru won't beable to tell if had the car tuned or not.

If you modify your ECU/tune and it causes problems, SOA can declined coverage on things.

yay for fraud. its the people who do this that make it hard for legit owners to get warranty coverage. And everyone wants to complain about the prices of the wrx/sti. SOA is gonna get their money back some how.

Or you get people like sajohnson who barks about how SOA isn't warrantying anything or why it is so hard to get coverage and SOA should do this or that. Seems the people who complain about the problem in the end is usually the same people who start it, the enthusiast who can't accept the responability for their actions.

Hey all, thanks for the feedback. I'm definitely not putting one over on Subaru, in fact, the dealer where I bought the car sold me the SPT intake / heat shield, and exhaust, and I paid them to install it. Another Subaru dealer in the area "advised" me to "get it tuned for the intake", but stopped short of making any sort of statements regarding what do to my future warranty claims. However, since everything is through Subaru, they will make it right one way or another, that's the whole reason I bought it from them in the first place. Anyway, it seems like having a shop tune my car sets me up for denial of powertrain claims in the future. Thanks for the advice and comments everyone.

As the original poster...one more thing to add, the tech at my the dealership where I regularly have my car serviced told me about a specific ECU update for the '07 STi the should have addressed my issue (stuttering, misfires, etc). They reflashed my ECU, let see, back June / July and that "solved" it for about 2 weeks. In retrospect, that period of automotive bliss might have just been the ECU relearning its bad old ways. Anyway, I'll keep NASIOC updated.

With regards to modifying the ECU, etc., I don't know sajohnson, but blackfang makes an interesting point. And yes, some of us can be what we claim to despise, screaming at the corps. when they try to put one over on us, but rationalizing our own acts of fraud.
Subaru is warranting the product they originally sold me, not the product I created(modded). Why should they be responsible for the results of my actions/changes to their original product?
We've also had Jeep Wranglers, including a Rubicon. It's interesting to read all the modders on the Jeep forums that think Jeep should pay for suspension and driveline repairs when the owner puts huge grippy tires on the vehicle and changes the angle of the driveshaft while putting major strain on the stock components, goes bouncing off ledges, scraping rocks and flying over bumps at 60 mph(like they've seen folks do on TV in the Baja) and then complains when OEM parts are breaking.

Think about it this way, they have to attribute the failure on the modified ECU map.

Example: if you get a protune, install an OTS Cobb AP map, etc. and your engine blows, then it's on your dime BUT they (dealership/SoA) has to prove that the power destroyed it. It's not hard in that case but reading about some of these engine issues I don't know if there is an easy way out.

One last note, someone on here might have mentioned that the dealers can get timestamps or extract past ECU info. Don't know much about it but a search should pull it up. Personally, I doubt they can do it but these new cars have so much electronics, who knows.
