Don't quote me on this...but...no i dont believe it comes with any software. You can buy the Pro Racer Package and that is software that gives you the full ability to tune your car. If your car is running real rich because of a tune on the xcal, try hooking the xcal up and setting the tune back to stock. That should fix it if thats the problem. Its very easy to do...aka, self explanitory on the xcal screen.
