Flashing back to stock ECU code

akira42 · 04-10-2009, 12:05 PM

How does BMW tell that you've flashed back to stock code. I'm assuming they use some kind of checksum. Anybody know?

Flashed back to normal from what? Dinan?

Yea, or any flash tune. I'm just curious.

Well if its going back to stock from a Dinan, BMW already has on file that you have had the Dinan flash on your car and your car cannot be CPO'd, I am not too sure about any other ECU flashes though..
Maybe someone who has a flash can jump in.......

I thought that even though you flash it back, their still able to tell. I was hoping to get a little info on this.
