Can Dealership Detect AP Stage 1 Flash?

Killian Maynard · 01-10-2005, 01:46 AM

Assuming mechanically everything is stock, only running a stage 1 reflash, would the dealership be able to detect the flash?

Or would it be neccesary to run the stock map if a trip to the dealership was in order?

dealer can detect any flash, just not what kind. Dealer told me that a couple flashes are ok cause sometimes the dealer flashed the ECU when you go in for major service but if there is too many flashes recorded, then they get suspicious. Thats what I heard.

You need to run the stock flash...

Thats what I was thinking, my only concern is that if and when I had to take my car into the dealer for warranty work I would 1. reinstall stock DP 2. remove 2.2 ohm resistor and reinstall egt sensor (for gutted stocker) and 3. flash stock program. My concern is that a CEL (P0545 EGT temp too low) might appear at some point at the dealer which could lead them to discovering my uppipe cat had mysteriously dissapeared. If I were to do all that but flash the stage 1 instead, it would be less likely that a P0545 CEL appeared.

Once you flash your ECU, they can detect it. Going back to stock doesn't make the car exactly the same-

Since the 04/05 Accessport is the same, I assume your car will now read as an '04 with an automatic transmission- even after unmarrying.

Could they prove that you had something to do with it?

That was my thinking. If they detected some alteration, what's to stop you from just saying "hey, this is how the car came and I haven't touched it"? If you're just running a stage 1 with no other visible modifications, couldn't you just play dumb?

Well, the ECU tag that is written is for an '04 WRX with an automatic transmission. The case, however, says that you have an '04 WRX with a manual transmission- on top of that, there are several flavors of the MT ECU- ah791, ah792, ah793. The sticker on the case won't match what the ECU returns from it's ROM.
