Re: 3 years of supported apps?
OBDI generates trouble codes too, though, without the data logging capability required by law. That's the part I don't like. Far from being hostage to a carmaker's special equipment as the other poster wrote, I can pull those codes with a three inch length of wire or an unwound paper clip, by jumpering two pins together on the test plug and watching the codes flashed by pulses of the check engine light. It is true that the level of sophistication of the OBDI system is not as great as that as OBDII, but then neither is the complexity of the entire system as a whole.
