I don't know what would be involved in an upgrade -- obviously the wheel itself, but wiring?

Start with RealOEM or another site with parts diagrams and see what you can figure out about your car versus one with sport package or the paddle-wheel. You also will need to be able to recode the wheel or find someone who can, I'd bet.

As you can see, I have a few bits but really don't know the answer to your question.
