I did some reading 9n this a few years back. To my knowledge there is no .xdf available for the TCM's to be able to program one. You're also up against trying to find a reader and burner as most all the companies that sold them have run out pf stock after the chip shortage, and decided it's not worth the trouble to redesign a new one with the new chips available.
