All the ver 4 oft tunes are euro based earlier v1,2,3 tunes for usa cars were usa based.
Euro cars like mine dont have evap pressure sensor so no evap leak detect . We hace purge solenoid but no evap pressure sensor, so euro roms dont even look for evap pressure the pin on ecu on euro cars is vacant ie A35 pin 20 on ECU
Open you tune with hex editor search for ZA1J there will be three. the third one at about 13,000 hex is true calod of rom first two at 8000 and 10,000 hex are often altered in oft tunes
