Nerd alert! Think I'm going to get laptop-based OBD2 tool -update: ordered & success!

I'm slipping further and further into nerdity:

I've been looking at laptop-based OBD2 tools because the SG1 isn't giving me all the info I want to see. Specifically, I want to know about fuel trim, since that's something that would be affected by HAI and EGR. But fuel trim is one parameter that the SG doesn't offer.

Also, I'll be able to log & graph relationships between sensor readings, whereas the current SG 1&2 only let you view "instant" data, which is actually pretty useless if the reading changes frequently by its nature (e.g. timing advance, throttle position, load etc.).

I realize the SG2 is supposed to have a USB or flash media logging feature coming out, but I don't know if it will include ALL parameters, or just the ones currently accessible (e.g. no fuel trim).

Anyway. There you go. Data geek!
