Question Can an ECU map be stolen?

Okay, this is going to sound a bit tin foil hat.


I've edited this post for simple clarity but I'm happy to give specific details if it helps.

Simple question:
If someone had a remap dongle (pick one) or some remap software on a laptop, could they potentially plug it into the OBD-II port on my car and nick the map to put onto their car, replacing it with their map?

Assuming two stock maps.

The cars in question are:
My car (A4 B7 2.0T fsi special edition 220bhp)
The potential culprit - 2003 1.8T

Yes and no. There are protective features in most aftermarket tunes which prevent easy "ripping" of the modified tune file. That being said with advanced software/programming knowledge DMEs can be cloned and software exported.

Also worth noting a 2.0T FSI and 1.8T are going to have dramatically different tunes.
