Yes, Bethini does allow you to modify Havok FPS fMaxTime but SSE Display Tweaks has a better, dynamic implementation that auto calculates based on current framerate.
The game does not handle framerates above 60fps well, which causes the carriage ride to be funky. You need to use SSE Display Tweaks to fix that bug. Or lock your framerate. Locking your framerate can be done via the Lock Frame Rate tweak in Bethini Pie.
You're not generally supposed to install Bethini Pie inside of a mod manager. It is a tool. It should be installed as a tool. The error message picture is insufficient to diagnose the problem. Only the log would be useful to see the real cause.
