Keeping up with car on CPU!

Hey guys, I just got an obdII interface, does anyone else have one and could reccomend some programs. Its cool b/c I could monitor the O2 sensors, all four of them, when they are all active. Oh, yea, could you guys post some air fuel mixtures and stuff like that, I mean i have a typical setup. Any info is appriciated, yea this program is very accurate, matches my gauges as far as infos concerned.
