How does Ford know that this was installed on a vehicle?

When you send in your ecm read file(part of the process) that specific file is used to create your calibration (so to speak). Your calibration is also saved on fords server to insure there are no issues with future over the air or other types of updates. The same goes for Whipple calibrations for Ford vehicles.
