Toyota LC150 1GR-FE Firmware 89663-60Q61
A catalog overview of Toyota LC150 4.0L 1GR-FE calibration 89663-60Q61 and its engine-control application.
89663-60Q61.bin is cataloged for the Toyota Land Cruiser Prado LC150, also identified as GRJ150, with the 4.0-liter 1GR-FE gasoline engine. The Toyota 89663 part-number family is associated with engine-control software, so this file is best described as an engine ECU calibration.
What the engine ECU controls
The engine ECU manages functions such as fuel injection and ignition timing using sensor information and operating conditions. Its calibration helps determine how the 1GR-FE responds to driver demand and runs across different loads and temperatures. The exact behavior changed by 89663-60Q61, however, is not established by the catalog identifier alone.
Catalog identification
The complete calibration identifier is 89663-60Q61. The related catalog entry repeats that identifier without a stock, modified or feature-specific variant label. It therefore does not establish a particular modification or a software change relative to another revision.
The LC150, GRJ150 and 1GR-FE details identify the listed application, but they do not by themselves confirm compatibility with every vehicle in that model family.
