Note also that you must be CAN compliant to plug something on your CAN bus, unfortunatly the AtMega is not qualified for C&S CAN Conformance like the AT90CAN.

Also the ELM327/Arduino can be used as a "scantool" interface and be used with dozens of software running on laptop/palm/etc. using a simple 3-wires null modem cable.

The ELM327 v1.3 can easily retrieve 30-80 PIDs per second, which is more than enough. And it implements the basic ISO/VPW/PWM protocol but also the CAN protocol 11 bit and 29 bit, 250k, 500k, header filtering, etc

I agree the solution can move to the AT90CAN** for a 2.0 version, but it needs a PCB and all.

BTW we also use the MC 2551 with the ELM327.
For the code we actually use less than 10k for ISO, my ELM proto is about 12k, we still have space to play with.
