You can also use it as a tach!

Cobb hasn't exactly been speedy at adapting the AccessPORT to non-Subarus. They've been saying they were going to bring out the AccessPORT for a few Mazdas (RX-8, Mazdaspeed-6, Mazdaspeed-3) for a couple years now and nothing's really come of it.

If you just want to reach the tach signal off the OBD port there are plenty of units out there that can do it for you already, though:
