My car is OBD II but was built just before it was complianced, so it uses Mitsubishi's version of it (TS Magna 6G72). There's only one product available outside a Mitsubishi MUT-2 that can work with my car, but it's $200AUD. So many sad faces.

Edit: but this is awesome, another brilliant, REAL WORLD USEFUL app. Out of interest, how will the ability to read additional cars be added to the app?
