Why don't you just download the latest parameters and everything...that's all the new revision is. It's a quick download and you're almost guaranteed to need it.

Rev. 5 will only work properly with '02-'03 WRXs. Rev. 6 adds a wire that was added to the '04 ECU. Can't recall what that wire is at the moment, but it makes a difference.
