I have Alex Peper's OBD2 scanner with a really crappy laptop. I tried it once with my car but I couldn't get the virtual gauges to work, probably because I don't know the software well enough. Seemed like I could pull codes though, if there were any to pull. The latest software version might fix my problem but I can't update it because the laptop has only a floppy drive for I/O and the floppy drive on my desktop computer doesn't work, heh...
