What is the difference between the ARC & AVY Engine

The ARC is the earlier ones, the AVY had changes made to it so it comformed to some new emission laws (euro 4), and you can also mess with the ECU with the port behind the ashtray on the AVY engines.

There may be other changes but non that I know of.

Yep, I understood what you meant, just hedgehogharvey referred to the port and I just wanted to mention that they all have it, what you can program or play with depends on the computer inside and the ECU brand as you said
