Just wanted to share what I've found while sitting in my car right now: Enter an OBD-II command: atz atz: > ELM327 v1.3a Enter an OBD-II command: atdp atdp: > AUTO Enter an OBD-II command: 01 00 01 00: > 41 00 BE 3F B8 13 41 00 88 18 00 13 Enter an OBD-II command: 01 00 01 00: > 41 00 BE 3F B8 13 41...

Yeah, that's what I was thinking about. The other thing I considered was to just do a sweep of all standard mode $01 PIDs a couple of times then base the support on whether or not they respond with anything. Both seem kinda hack-ish, but I guess that's what it takes here. :-/

Thanks for the feedback!

Greetings! I know this is primarily a GM community, but it seems like y'all have a better grasp of things OBD-II than most everywhere else I've been around the web. The case I'm working on right now is with my 2009 Lancer GTS and an ELM327 USB dongle that I have. I've written some simple python code...
