I've always been curious to know just what it is that Subaru changed when going from the A4TF800F to the A4TF810F revisions of the 2005 WRX MT ROM. At the time (over 5 years ago now) my complaint to the dealership that the car knocked under certain conditions lead to the reflash. Afterwards I was convinced that power was down a bit, and the knocking, while it seemed to be reduced, was still present.

Having finally gotten an OP2, I pulled the image and compared it against the stock 800F ROM that's floating around. I don't see any differences anywhere, at least not according to RR. Was this just a placebo fix? Anyone have any idea what changes (if any) were made?

There are ALOT of tables not defined by Romraider. Only person that can tell you the changes would be Subaru Engineers.
