This weekend at the Greenberg Show in Edison, NJ the Command Control Demo Group will have a lap top with the Legacy System Utility running so you can learn to make your own upgrade modules and edit your engine info. I'll have some black modules with me for sale so you can make upgrade modules to bring home or bring your remote and base and do it right there with my modules.
The laptop also has the DCS software for anyone still needing that upgrade (bring your TIU and Remote). Version 4.20 is still the latest.
