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

This tune I flashed was last modified in 2015, so it likely isnt a v4 tune. In that case, I'd still need to take care of the evap system throwing a code or get smog checked before the code is triggered. I'm guessing i messed something up by overfilling the fuel. I suppose Id have until the next smog check to figure it out, and my stage 1 tune is probably smog-able.
