data logging software

so the ecu for my civic(obdI) has a data logging port on it. I dont really know what this can be useful for, but ide like to find out.

so i have a few questions.

What can it be used for?

What software do i need on my pc?

will the hondata software work without a hondata unit installed?

so many ppl on here who tune cars and nobody can give me some advice

so much for a tech. forum
