Hello, just like every video game out there it seems a trick is needed to use a special feature. The feature does work at whatever you change the energy sub in/out to, personally I use 70 out and 84 in. The trick is to not use hurry up offense and not to skip the after the play segment. In otherwords after you run for 12 yards up the middle, let your player celebrate on his own and let the game naturally take you back to the playcalling screen, don't skip the after the play stuff by pressing x (PS2). This way works for me.
