have you tried looking at your target consul? errors that don't show up in compilation because they are not syntax errors will appear there (ex. code with the gyro not on analog 1 will compile because the syntax is correct, but will not operate because it is not on analog 1).
if you are 100% sure that you connected all of your pwm's correctly on both ends and have declared all of your motor controllers correctly, then they are not receiving a signal from the side-car which could electrically be (based on previous info):
1. Bad C-Rio Card
2. Bad Side-Car Cable
3. Bad Side-Car
4. Bad Motor Controllers
the best way to try to determine which it is, is to replace each individually to see which is the problem... a very expensive problem if you don't have backups...
