I've heard of people that say their dealer could never tell they reflashed, and other say the dealer voided their warranty because of it. Supposedly the mechanics can tell how many times the stock ECU has been reflashed, but I don't know for certain. Unless your dealer is cool with you modding the car (which they usually aren't) then you should leave it alone. Or just screw the dealer and do your own maintenance.

yes they can tell if your ecu has been flashed. having a stage 2 flash doesn't automatically void the warranty.
since you have an 07, it is very highly recommended that you get some sort of tuning (cobb stage 1, openecu stage 1) on it before you start doing any mods. |

Good luck on that.... I spoke with the service director @ our sister store which is Riverside Subaru & they're saying it does indeed void warranty & they can tell very easily.

your service director is wrong. no mods automatically void your warranty. they can, however, be cause to deny you warranty work but the burden of proof is on the dealership. they must prove to you that the mods you have done accounted for the problem with the car.

the subaru dealership that i go to has speed parts like the cobb accessport and other stuff... the guy at the counter said that as long as they get the parts and they install them, they wont void the warranty. they will only go through a well known acredited supplier like cobb or perrin. and of course anything they sell on subaruparts.com or spt.com.

ANY modification you do may void warranty, Installed and bought at a Dealer or not. Its at the Descretion of the Dealer or SOA. Plain in simple if your worried about warranty dont mod the car. Like someone complains about there clutch slipping, but the previous night i was watching them drag race there car at the track for 3 hours, and they swear they dont beat on there car.

Many of the salesmen that work at Subaru dealerships have or had own a Subaru. I was talking to one Subaru salesman near where I live, and he was telling me about all the parts he installed as well as able to use the lift.

A Flash will void most of the warrenty. You might still have warrenty on things that aren't effected by the power output of the engine. For example: The brake lights.
And yes most will check on your ECU if you bring it back for a problem. |

Hm...interesting. I am curious to see how the dealer can tell if the ECU has been reflashed. In order to do that, they would have to pull the ROM off the ECU, do a checksum on it and compare it to the stock image. Either that or they have software to view your maps off the ROM but I am yet to see that at the dealership and they'd still have to pull it off the ECU to check. On top of that, each MY has multiple revisions of the ROM so there are multiple versions of the ROM for any given MY.....so if they check, they better know all of them and have them handy to compare to make that determination. They could just read the ROM header and see if the ECU ID matches but AFAIK all reflashes retain that.
I am pretty sure there's no reflash counter being incremented when you reflash. The only persistent memory on the ECU is the ROM and when you reflash, that is what you're blasting away with the new version so I can't see how they could tell unless there's another mechanism that I don't know about in the ECU that keeps track of that based on the sequence of SSM commands that lead to the reflash....doubtful. I really, really doubt they can tell. But go ahead and ask them....I wonder what they will tell you |

yeah there was a law passed a while back that makes it illegal to void a warrantee due to adding or modifying your car unless it has been proven through testing that indeed that exact modification or part WILL cause a certain problem.
anyone remember the law ?? |

My dealer asked me everytime I flashed it back to my OEM was this car ever tuned? They fish for it because they can't tell. A Checksum in a PC or ECU is the dealer running the diagnostic against the current loaded map at the block level looking for inconsistent algorithms and will return it a CRC or error. If your matching against the OEM map the dealer cannot tell. I have proven this more than once on my 07 STI that is why the AP will marry to your ECU and download the stock mapping for when you have to make it look all stock again.
