I doubt that somebody near to you is able to hack, correct and reflash UJ WA12212970WWW chip.
The last official reflash (D5854EC7 pack) does not solve neither secondary air nor hesitation problem for 100kkm\3year used EJ204 engine.

Sasha, I think I am alone and no help around me. Since Forester is not wide spread in my country, there is no specialist for flashing. :(

As a temporary solution try to solder 2200 pF capacitor to 17 and 31 connector pins.
On a rare occasion of hesitation reset the ecu.
