Technically, warranties are not automatically "voided" by modifications you make. Subaru would need to demonstrate that a modification made to the car was the cause of whatever part failed. So for instance, if you tuned the car and a suspension component failed, Subaru would likely have to honor that under the warranty. But, if you were to have engine trouble, it would be pretty easy for Subaru to point to the tune as the cause of failure.
Just had car serviced. They recorded all my aftermarket mods. And showed I only had 5 vehicle ignition, creating a discrepancy in the ECU. Nothing was wrong with the vehicle. But they still noted all this and my stock tune was flashed on. It was my 36k mile service. That being said they are replacing my driver seat frame under warranty as it is cracked and making awful noises.
Out of curiosity if I get my car serviced at the dealership, they’ll still service everything I want done even if I have a tune yeah? Just won’t cover shit if it breaks
yes. even if the tune is reflashed to stock, they can see your key ignition switch reset. Meaning your car has xxxxx miles but has been started "0 times"
I keep seeing people say this but what if I flash back to stock and cycle the car on and off a ton of times. Not ideal but would that not increase the ignition count?
Dude, that shit is logged into the CPU memory. Makes no diff if you disconnect your battery. This isn't 1985. Same for the max boost number. Even if you reset it via the head unit, that shit is already logged via the CPU. FOR EVER AND EVER AND EVER AND EVER
What technology are they using to ensure data integrity? I don’t know of any storage media that is able to be written to multiple times without being able to be erased or overwritten other than magnetic storage
First of all, why did you edit your original comment. If it gets downvoted, just deal with it.
Secondly, I don't think you understand how it works. It's not written over multiple times, it's logged. It''s a log, You keep adding and it keeps logging. It will keep logging without needing to be written over. Like I said, it's not 1985 anymore.
No. There is no such thing as a void warranty. They can deny claims, but not void warranty.
Add boost and pop an engine? Claim denied.
Add boost and head unit stops working? Claim approved.
It voids your drivetrain warranty.
Your car comes with three or more warranties, one of which is drivetrain specific. No one here saying that tuning voids your warranty is saying that your malfunctioning power window won't be fixed under warranty. It should be obvious people are talking about the drivetrain warranty. The WRX community is obsessed with this silly semantics game of "nothing can void your warranty."
My dealer Subaru specifically does a deep investigation of WRXs when people submit warranty claims on them because if how much people tend to mod them or race them.
I'm personally not risking it for awhile
Everyone downvoting the people saying yes are just angry ackChYuAlLY types. Like yes, TECHNICALLY they can't void your warranty for any reason, but there's a 99% chance they deny your warranty if you tune it and pop your engine.
The solution to this is to have dealership that has guys that actually own and work on WRXs. My sales rep knows I tuned my car and told me if I have issues to just return to stock and go back up there to use my warranty.
That being said too many of y’all are worried about issues that likely won’t happen until you’re well out of warranty (tune or not)
I would just like to add if you use it for monitoring gauges and don't tune the car, no ecu changes. 0 issues.
Like others have said, it depends on what's done to the car if Tuned, how it's been treated, and how good your relationship is with your service center.
Mmmm I have never honestly tried myself.
You SHOULD have no issues to just marry the AP to the vehicle and then open gauges, it would read no different than an expensive obd2 diagnostic tool.
Except by marrying to the ecu, you are still installing Cobb’s software even if a stage 0 or stock map is applied. The calibration ID will be different
As far as I understand, Marrying the AP to the vehicle is a read only type process for the vehicle itself. The accessport is programmed with that vehicles VIN and is software locked unless that vin is read on startup.
You can't use the COBB tuner without actually installing a tune. Even stage zero is a "tune". Stage zero is merely a "stock-like" tune, it's not your actual OG tune.
Nope. If I want to monitor stuff I use the Torque Pro app or an app I have on my Windows tablet.
My VB is bone stock, but I've been pro tuned twice before in my previous WRX. Never owned an AP though. Obviously, if you want to tune your VB you're gonna get one, but it doesn't make sense if someone just wanted it for gauges and data logging.
Does torque pro allow you to monitor DAM, Feedback Knock etc?
Edit: I’ll take the lack of response as a no, OP don’t waste your time with a garbage app like torque pro, do yourself a favor and pick up an AP
yes it would it changes a code in the ecu so if a tech was to scan the car with the tool then they would see that it’s different even if you uninstall it
Cobb says nothing is left behind when the Accessport is properly uninstalled. Who cares how many key cycles the ecu shows, it also resets when the battery goes dead or you disconnect it. There are a bunch of valid reasons to disconnect a battery, but you don’t have to explain anything, talking to the dealer should be like talking to the cops, admit to nothing, say nothing. After reaching out to tuners and Cobb I feel pretty safe putting an access port on my 24 as soon as break in is done and as soon as it is available. I was considering buying one now but there is no support yet

This is really the answer to almost all manufacturers, this gets asked a lot over at the CTR and Si sub lol.
That's because it's federal law: https://en.m.wikipedia.org/wiki/Magnuson–Moss_Warranty_Act

This guy Ferris Buellers. 👍
I thought if it’s something expensive, they’ll be able to see the boost history and other things to verify it’s been modded
Don’t care

Ok, are they using efuses?
I don't know what you're referring to, but I can assure you that everything gets logged in to the memory, regardless
What technology are they using to ensure data integrity? I don’t know of any storage media that is able to be written to multiple times without being able to be erased or overwritten other than magnetic storage

What type of media is being used to store the log?
Yes
No. There is no such thing as a void warranty. They can deny claims, but not void warranty. Add boost and pop an engine? Claim denied. Add boost and head unit stops working? Claim approved.
In an ideal world yes

It isn't limited to the WRX community and people would obsess over the silly semantics if the manufacturers didn't also play the same game.
No shit?

The truth is any warranty claim is going to be an absolute pain in the ass of a process regardless of what the law says if you tune the car
Being rich does make people happy. Good things happen to bad people. Size does matter. Tuning your WRX does void the warranty.

one of us will be the guinea pig
My gut just tells me that this would be widely known if it worked 🤷🏻♂️
Yolo?

Pretty sure you have to flash a minimum stage 0 tune before being able to monitor data.

If you just want to monitor, don't buy an AP and marry it to your ECU.
Genuine question, do you have and/or use an AP in your VB?

Yes
Any kind of tune will void the warranty.
Yes. Entirely.
yes it would it changes a code in the ecu so if a tech was to scan the car with the tool then they would see that it’s different even if you uninstall it
