Anyone ever use this type of CPU upgrade?

I'm wondering how would you know where to re-map and tune in the air to fuel ratio without pre-made programs. Does it come with other peoples set-ups used before? It talks about MAPS but does not say if it comes with any software. Obviously you will need a laptop or computer also.
