If there are any, make note of them. Reset the ECU. Pull fuse 16 for 10 minutes. Drive around and see if that changes anything.
You may want to check codes again in a few days to see if anything is there. If you still are having problems. I'd suggest pulling the plugs and looking at them.
other possibility is there is an excessive amount of carbon built up in the combustion chambers which is causing pre-ignition and the pinging. in which case you should have the engine cleaned using one of those motor-vac things.

On the new subarus I'm not sure if you can pull just a specific fuse to get rid of power to the ECU.
