Toyota LC200 4.7 2UZ-FE 89663-60C00_ST1_E2 SV 4000 p..
A catalog overview of Toyota LC200 4.7 2UZ-FE calibration 89663-60C00_ST1_E2 SV 4000 p.. and its variant labels.
89663-60C00_ST1_E2 SV 4000 p.. is listed as an engine-control calibration for the Toyota Land Cruiser 200 with the 4.7-liter 2UZ-FE V8. The 89663-60C00 identifier belongs to Toyota’s engine control software part-number family.
The engine control module uses its calibration to manage functions such as fuel delivery and ignition timing. Those controls affect how the engine responds to the accelerator and operates under different loads. The catalog name alone does not establish the precise changes made to those controls in this file.
Understanding the variant label
ST1 commonly denotes a Stage 1 modified calibration, while E2 commonly indicates an emissions-related modification. SV 4000 p.. appears to describe an additional setting associated with 4,000 rpm, but the abbreviated label does not reliably identify the function being changed. The exact tuning behavior and emissions configuration cannot be confirmed from the filename alone.
The related catalog identifier 89663-60C00 identifies the base calibration family. It should not be assumed to have the same modifications as the file carrying the ST1_E2 SV 4000 p.. suffix.
