Yes, every time you reflash it for any tune a new CID # is created. If its a Subaru Recall update there is a certain Letter & number givin to the ECU which tells subaru it was a different subaru re-flash.

There is a product that many of you use that saves the original CID/CVN #s. Open source and other means of tuning wont save these numbers. As far as I know there is only one product out there that saves these numbers and has software to re-flash those Factory #s back to the ECU. If you open source tune or use other lap-top tuning software the CID & CVN #s are erased and show up as ########.
