Stock and modified catalog labels
The filename RAV4 2.0 3ZRFE 89663-42S60_ST1_E2 SV 10000 p. identifies a modified variant. ST1 commonly means Stage 1 tuning, while E2 commonly denotes an emissions-related calibration variant. The additional SV 10000 p. text is part of that filename, but its precise meaning is not established here. The labels alone do not show the actual calibration changes or their effect on power, emissions or drivability.
The separate entries 89663-42S60-A.bin and 89663-42S60-A carry the identifier with an A suffix. Their names do not establish whether they are stock or modified, or whether they have the same contents as the labeled Stage 1 variant.
For diagnostic purposes, the complete calibration identifier is more useful than a similar-looking prefix. It helps distinguish this RAV4 3ZR-FE catalog entry from other Toyota engine-control records, while the vehicle’s own identification and controller details remain important when checking an application.
