No, there's no way of a dealer knowing. I would go as far as saying most dealerships will ignore ecu re-maps, unless there was a real bad underlining issue with the vehicle and they had to do some proper testing on it (in order to get out of a expensive warranty claim.) I'd imagine only then they would check the ECU settings. The guy i normally use for my ECU remaps said he does allot of work for BMW and VW dealerships. He said they get their demo cars re-mapped to fool customers into buying them!
I've done about 50 miles with my tuning box on and it's absolutely brilliant. Sober as 15 year old dog one minute - a raging bull the next. My biggest fears of fuel economy dropping and the car starting to smoke were premature. The economy has actually improved by 5-6mpg and there isn't a hint of smoke.
