Toyota 89663-60E31 Firmware for LC150 4.0 1GR-FE
A catalog reference for Toyota 89663-60E31 engine-control firmware associated with the Land Cruiser 150 and 4.0-liter 1GR-FE engine.
Toyota 89663-60E31 is cataloged as engine-control firmware for a Land Cruiser 150 with the 4.0-liter 1GR-FE gasoline engine. The engine control module uses calibration software to manage engine operation, including fuel delivery and ignition timing.
What the catalog identifies
The filename LC150 4.0 1GRFE 89663-60E31.bin associates the complete calibration identifier with the Land Cruiser 150 and 1GR-FE engine. A second entry, 89663-60E31.bin, identifies the same code without a vehicle or variant label.
These names support an engine-control association, but they do not describe a specific change made by this revision or identify a modified feature. The listed vehicle and engine should therefore be treated as catalog context rather than proof of compatibility with every Land Cruiser 150 4.0 configuration.
