The identifiers in this entry belong broadly to the Toyota and Lexus engine control calibration numbering family. Engine control software manages functions such as fuel delivery, ignition timing and emissions control, although the exact application and behavior of these particular identifiers cannot be established from the catalog names alone.

Catalog identifiers

The related entries are 89663-02E21, 89663-08040 and 89663-60W82. The supplied identifier also contains 89663-0F17866 and 89663 -50L30. These strings should be checked against the original calibration or catalog record rather than treated as interchangeable part numbers.

No vehicle model, controller designation or stock or modified variant is named in the catalog entries. A matching number alone does not establish vehicle compatibility or identify a change made by a particular software revision.
