If you have an RTP then you can tune it and save the tune on it currently. If you update to a Demon simply upload the saved tune to it. If you have the chip version you can't tune it and if you get a Demon you'll need a dealer to transfer the tune for you.
@CiViCEj8GsR Please make sure you've followed the first part, that the drivers are installed, and that it shows up in device manager. If you still have no luck, please inquire via email for support.
