AccessPORT Available for the 2008 Models
 

I've been receiving a bunch of questions about compatibility lately.

The AccessPORT works on all North American models, from 2004 through 2008.
If your RX-8 has a North American PCM, the AccessPORT will work for you.

It does NOT work on the new '09s as yet.

There are, apparently, versions for the European and Asian markets.

At this time, I do NOT have access to those ROMS, so I cannot yet provide calibrations to customers in Europe or the Asian countries, unless they possess an American-spec car (which happens quite frequently).

Canada is compatible, BTW. I don't have confirmation for Mexico or South America, but it seems that most Caribbean countries DO use the North American spec PCM.
