You either installed the foc wrong (hard to do it wrong) or need to adjust the 2-speed. You kind of lost me there on the other question.

A clear post will get you much more info. You may have a tuning issue as well. A bad tune will cause a vehicle to not shift. Always test the radio system for proper function and range before starting the engine. Make sure the batteries are fresh or fully charged.
