What the Euro 2 label means
The TUN_EVRO2 suffix identifies a tuned file associated with a Euro 2 emissions setup. In practice, that label commonly indicates changes to emissions-related monitoring, but it does not establish which diagnostic checks were altered in this particular file or whether a vehicle meets any emissions standard.
The related 89663-20212 entry is the base calibration identifier. The suffix distinguishes the tuned catalog variant from that base identifier. The available names do not establish an exact vehicle application or the detailed changes made to the calibration.
