I doubt you need an ELM323, on AVRFreaks a couple of people did it without an ELM. Search "obd" on their forums, some people even give some C codes to do it. It seems the ELM is slow too.

I'm sure we can drop the ELM.

To init the OBDII you send 0x33 at 5 bauds then you switch to 10400 bauds and send some commands, plug the Atmel directly on the OBDII like this:
(ISO protocol only)

You could also switch to an AT90CAN128 to speak CAN to your car I guess?
