No, as far as I know the undersheath doesn't give him any additional ability appart from linking the suit to him.

And even though Tony blew up his armors in Iron Man 3, don't forget that he didn't blow up his money, the suits' blueprints, or his ability to make more.

And that it's been revealed that the Iron Legion will be rebuilt for Avengers: Age of Ultron, as Tony will create the A.I. to help him control the suits.
