Not sure how similar the ECU is inside but they have developed a prototype AccessPORT for Ryan's Subiesport 05 RS. With the flexibility of the new AccessPORT I think you can expect to see something in the not too distant future.
Some of you may have noticed on COBB's forums they already have AccessPORT forums up for other non-turbo vehicles that they will be providing AccessPORT's for.
Since they plan to release the Nissan, Mazda and Mitsubishi in January of 2007 I'm hoping they'll include the normally aspirated Subarus at the same time.
