I have 1500 miles on my 07 WRX, and am looking for a few power upgrades, without digging into the motor.. I'm wondering if this could be grounds for them to deny any claim, or is there a way to reverse the map so they don't know about it?

Well yes, and maybe no... With the Accessport you can flash back to the stock map anytime you want to. This will get your car to the same settings it ran on before you used the AP. However I've heard that the stock map that the AP flashes is not completely identical to the one from subaru.

I could be wrong about the stock maps not being the same, but if they are I'm not sure if subaru can tell or not.

Anyone?

Thanks for the reply. I'm hoping for a definitive answer.... I'm looking for some non-warranty issue power upgrades!

COBB over-writes your ECU map, and from that point forward it will never be the same as the original stock map. Depending on what you get serviced, however, subaru shouldn't really look at your ECU anyway. I believe Tactrix can save your stock ECU data, and the UTEC might not erase the orginal stuff either

The AP V2 copies your current map to the AP when you marry. When you unmarry, it copies the stock map back.

If there is an engine failure and the dealer was smart and found about the reflash the yes they have every legal right to deny coverage.

If you have a failure be a man and don't try to defraud Subaru.

^^ what he said... since you have to copy your stock map for later use it is then possible to flash it in the future exactly as it was stock.

But doesn't this change the skim code on the ecu?

SPT Power pack.

Does not add much (if any) power, but it makes it more fun to drive

The short answer is that anything you do to your car can be used to deny claims of anything affected by your changes.

If you put headlight film on your headlights and they crack, you cann't warantee your headlights. If you install engine management, you're pretty much going to be denied any claims on your drivetrain.

Other tidbits:
UTEC = piggyback system that does not reflash your ECU.
Accessport = saves your ECU flash and returns it when removed (but checksum is changed)

The power packs can provide substantial power increases. They are waranteed in Europe, but not in the US as far as I know.

If you're worried about maintaining the car's warantee, then I'd recommend driving it at stock power levels. It's still a fun car and plenty fast for daily driving.

SPT power pack IS fully warranted and only in the USofA

The Prodrive PP are not.

Not at all. You won't be the first, or probably even the 1000th or 10000th to use AP. If I had to guess, I'd say that AP is probably the most popular 1st mod for 04+ WRX and STI's. The reason being is that the stage 1 map on AP seems to be safe and it wakes up the car alot. When you get tired of that you can step up to Stg. 2 with some other parts and you'll see more power that is still reliable.

But, keep in mind that anytime you modify a car you open yourself up to rejection by the dealership. If you walk in to a dealer wanting to get a clutch fixed under warranty and they see that you are running stg. 2 with meth they are probably going to shoot you down. If you have clutch problems and they see that you take care of the car and you have only reflashed to stg 1 will they still reject you? Maybe, maybe not.

Better way to add HP and not hurt the car/warranty? I know, noob questions... lol

Not really. Many will say that instead of worrying about making more power you should focus on brakes and suspension because the added driveability will be more noticeable than a few extra horsepower. To a point, I agree with this. If you have struts/springs, endlinks, swaybars, BBK, etc... you probably won't have much trouble with a dealer rejecting a warranty claim on engine/drivetrain problems, but you could.

The problem with warranty claims is that nothing is cut and dry. Nowhere in the warranty information does it say that claims can be denied because of X part or Y part. This leaves warranty claims up to dealership interpretation.

The skinny is that if you are worried about having a great warranty you should just leave your car stock.

Good luck.

Even if you're stock you're gonna get hard time.

Thank you all for the insight.. I've done springs, looking at the rest of the suspension before I get the AP..

when ever the code on the ECU is changed, the check-sum value increases by 1 (one). A good tech will look at the check-sum value and see it is not 0 (zero) as it should be untouched.

Start with improving one thing that will never be a problem, you. It takes a while to learn the car. I say touch nothing for the first set of tires. That gives you time to learn about the car here, and well as improve yourself. New tires make a big change as well. And at that time you will have found (and fixed under warranty) any factory defects. Make sure you have a solid platform (the car without defects), a solid plan (read a lot here), and the finances to do it right.

If your worried about your warranty you should not mod at all. But really what is going to go wrong. Do the COBB AP and your power window stops working, your covered. Brake your transmission or screw up the engine due to a mod you have done, the only right and honest thing to do is to pay for your own mistake. You get to live once. So live a little. Get a AP. You will like it.
