Custom OBD PIDs

[phaux]

Has anyone ventured into the unknown that is Custom PIDs? I know it's a real popular thing with the Evo crowd with Mode 23. It looks like the Mirages have Mode 21 (similar to 22 and 23) enabled. I used Torque Pro with the Mitsubishi LT Plugin to scan for any responses, and I found 24 PIDs that return data. Now, what that data is, I couldn't tell you. They could be literally anything the ECM can see -- A/C compressor status, CVT ratio, buttons being pressed on the steering wheel or dash, door status (open/closed/locked/unlocked), etc.

I haven't found ANYTHING online related to the Mirage, but my attempts to match up known PIDs for models like the Lancer or Outlander to the data that comes out of my car turned up nothing.

I did some testing this afternoon and mapped two PIDs:
(Table moved to bottom of post)

Like I said, there's 24 total that I found, that's only 2 of them. Different MYs may return different data or even different PIDs. Many of them may require a formula to read (see the official Mode 01 PIDs) correctly. There's going to be redundant data, but one unique one is that A/C status. I'll update this more when I figure more out. Maybe someone else has done this before?
