It's not a tune so I don't think you need an unlocked DME.

Haven't looked into it, but I was under the impression it's a piggyback like JB4

Find a friend or JB4'd car at a local car meet. They're great for the price, but too much input lag for my taste. JB4 far more customizable than racechip too fyi
