Hey Sean. Basically, Subaru released the SSM (Subaru Select Monitoring) communications protocol over OBDII interface. People have figured out how use this to read and write tables in the ECU ROMs. Cobb Tuning built the AccessPort around this technique and made it into a very successful product. I think the AccessPort is a nice turnkey solution for most people.
Me, I like to fiddle with stuff...
