Impreza (non Turbo) probably has a JECS ECU, not Denso. Check that (should be written on the top). If it is not Denso, then sorry, it is not supported by ECUFlash.
If you can read the ROM but there are no definitions for it, post the ROM so the openecu community can work on generating a definition for it.
