I've read that there's a counter on the ECU that counts the number of times the ECU has been flashed. Assuming you start with 1 as the stock map, flash to a aftermarket map, then back to stock the counter would show 3 instead of 1. However they only way they could tell you did this is if your car was hooked up to their ECU programmer. Depending on what you take your can in for may lead them to try and trouble shoot the ECU.
