Sorry but the Accessport has been sold.
Really you probably don't want to use a Accessport, unless you want someone else to do your tuning, like Mazdamaniac. The Accessport is really only any good if you had a USDM model RX8, not a JDM RX8.
The better way to go would be to use the Mazdaedit program that Brettus is using, or get him to do your tuning for you. He does a good job.
Hope this is helpful
