I think i've made up my mind who i'm going to get a map from for my S3. Before I spend a significant chunk of cash on it I would like to check that it's not already mapped. I've read something about using vagcom (which I have) to check the number of times the ECU has been flashed. In my old golf you could measure the air intake values from which the peak value (when ran through the rev range) should give you an indication of whether it's mapped or not. Will I be able to do the same on the Audi? Is there anything else I can log to check?
