Tuning with ElmScan?

I have the ElmScan tool and software for reading codes and even datalogging on my 97 GT using the laptop, but I was wondering if there is any software available to do tuning. It would be great to add a few degrees of timing and take out a little fuel on the top end.

So is there any software available for programming/tuning using the ElmScan tool?

If there is nothing available to tune using that, what is the cheapest and easiest way to start tuning on my own? I mean real turning. Not answering yes or no questions in a pre-set box.

I knew tweeker was common for my 88 mustang, using that old EEC-IV, but I didn't think it worked on OBD-II like my 97 has.

Hmm, do I need to buy anything extra to program both my 97 and 88?
