I don't think it cares about the TC at all. It cuts until the RPMs drop to a certain RPM and I think that's as complex as the programming gets. All the TC does is make it feel jerkier when DFCO kicks in then kicks out once down to where the FI resumes to keep slushboxes from stalling.

I wish it was selectable... shifters always seem to be lacking for buttons.
