Default Cobb AP clarification

I know the generally accepted idea about the Cobb AP is that it 'can' void your warranty depending on the dealerships service department. Some people have mod friendly, some do not. I ran across this thread the other day http://forums.nasioc.com/forums/show....php?t=2349839 and some of the information on it goes against the 'norm'.

(If you don't want to follow a link and read the other thread.) They are talking about ringland failures and Cobb AP with warranty claims. An email from Cobb explains how it all works with the unmarry and a person claiming to be a Subaru Tech confirms. (Same VIN, CVN, CID, etc).The tech confirms that the software they use does not detect number of times flash has taken place but it detects different CVN/CID numbers, which the unmarry will revert back to exact stock numbers for you. The tech also claims there is only one product that will work and hold the numbers for you, which is the AP unmarry tool. (Actually, he says he will NOT disclose the information, but if you read the thread you will get it)

The thread is a bit old, and I'm a little confused that if this information is correct and confirmed with such valid sources, why is it considered normal that "Cobb AP voids PT warranty"? The thread seems to be a small little gold mine of information. Has this information been proven opposite?


TLDR: Good thread explains how Cobb AP and the Subaru Select Monitor work. Cobb and Subaru Tech are confident that the SSMIII cannot detect a difference in ECU when using AP unmarry.

It's a risk. I've heard from a couple Cobb employees that it's undetectable if it's uninstalled before going to the dealer. I've also heard from one Cobb employee that if Subaru looks into it deep enough they can see a flash count.

I guess there must be another method of seeing into the ECU. They claim that;

Cobb Email: " Finally, there is no evidence that Subaru ECUs or tools have the ability
to determine how many reflashes of the ECU have occurred. There is no
known counter mechanism employed, nor any evidence that such a system
sits in-line with the ECU to capture this data. The reflash process is
very sensitive already, it would seem a recipe for disaster to try and
employ additional complexity."



Also;

It's my understanding that they can't tell the ECU has been modified, but what they can see is that the flash counts (number of times of the ECU has been reflashed) on the ECU don't match the number they have in their system. Now if Cobb has come up with a way modify the flash counts, that would be news to me.

Subaru Tech: false, doent exist that im aware of. My software doesnt even tell me any of that using the Subaru Select Monitor III. Just tells you the current CID and CVN #.

I know this doesn't really answer the question but...I was told by the owner of a Subaru Dealership (he also owns a Subaru specific tuning shop) that dealers do not have much control over any big warranty work...so there isn't really a mod friendly dealer anymore.

Quote:
Subaru has changed there processes on wrx and sti models...they will come to the dealer to investigate the failure...
Maybe the Subaru rep can do more to investigate the problem more than the tech that works at the dealership can. I honestly have no idea. I don't think there is an answer to this question. Hope that helps.

Oh look, another thread about modding, tuning, and warranty. It's been discussed a million times.

Can an AP VOID your warranty? No. An AP, downpipe, fart can, etc cannot VOID the warranty, but can be cause for DENIAL of warranty work. VOID is incredibly strong, and rarely happens. Denial is a better word.

The AP copies a similar version of the stock tune. Does that mean it will replace it 100%? No. Anytime you touch the ECU you risk the denial of warranty work. Which, depends of the tech and dealer.
