sct " failed to unlock ecu"

Compare what you have listed in Device Info against what SCT has available. An update might help.

Monitor Firmware 1.1.111
Vehicle Interface Module Firmware 1.3.106.2
Tune Revision version 1.11

The TSX is a little picky and have to follow on screen instruction to the t. I have used many and once they are set up, they seem to work well.
