If it's a WRX/STI ej20g ecu it'll work. The one in your link is for a legacy twin turbo. Also note that a Forester "ej20g" is actually an ej20k in all ways except the name, so their ecu will not work. Kind of confusing.
Additionally, prefacelift Legacy/liberty ej20g ecu's are only 8 bit and are not compatible with rob's tune, even though they have a space for his chip and everything.

There's a list of the correct ecus to purchase in the robtune thread.

That is a Hitachi ECU. It will not work for a Robtune. A Robtune needs a JECS ECU.

It's more than just a hitachi vs jecs thing - the twin turbos and other turbo engined subarus came with hitachi and jecs ecus, (example here:

Robs tune ONLY works with WRX or STI ej20g ecus. And those are made by jecs as you said.
