On that very issue I think tts was one of, if not the only, tuning module that allowed you to save the oem calibration for future use if one removed mods and wanted to put a bike back to oem specification. The only problem is you saved it to your pc and if a bike is sold after that, many people won’t have the oem calibration to return to. It is the oem calibration which ultimately unlocks it from tts
HD dealers cannot reflash your ECM if the bike has a TTS system installed. TTS locks out their dealer Digitech laptops/desktops.
