I've been playing with writing some software to go with my ELM-327 USB device, and I've been wondering if anyone knows much about enhanced OBD-II modes for the Lancer, specifically 2009 GTS.

Last night I ran a sweep of modes $10 through $30 and found that most simply echo back with what I hit. For example:

There are some modes in the range that simply don't respond at all, which leads me to believe that the ones that do respond are valid modes but I'm just not passing them what they expect.

I've not had the time to read the SAE docs very intently to see what the proper means of hitting these are, but I wanted to know if anyone here happens to know what these extended modes are what data is available by them.
