I've been looking around for ODB-II PC software, and there are a bunch out there...The ones offered by Autotap and Harrison seem to be the best (clean interface) IMO. On the Harrison site they have CANScan, for newer cars (350Z and G35, and other Nissans) using latest protocol, and ODB-2 S/W. The Autotap only offers "older" ODB-2 S/W.

Anybody around here have an experience with either of these vendors, or any other S/W?
