Toyota 89663-60X72 Firmware for LC150 1GR-FE
Explore Toyota 89663-60X72 engine calibration and the LC150 1GR-FE catalog variants, including SAP OFF and ST1 labels.
Toyota 89663-60X72 is an engine-control calibration associated in the catalog with the Land Cruiser 150 and the 1GR-FE gasoline engine. Its control module manages engine operation, including fuel delivery, ignition timing and emissions-related functions. Those controls affect how the engine starts, runs and responds to the driver.
The catalog contains two named variants rather than a clearly identified stock file. Their labels point to different modifications, so their named features should not be treated as interchangeable.
LC150 1GR-FE SAP OFF variant
The entry WinOLS Toyota LC150_1GRFE_89663-60X72_E2_SAP OFF FULL_CVN OK_CRC OK_GEN2 is labeled SAP OFF FULL. SAP refers to the secondary air injection system, which supplies additional air to the exhaust during certain cold-start conditions to help reduce emissions while the catalysts warm up. The label describes a file intended to disable that function.
The same filename includes E2, CVN OK, CRC OK and GEN2. The CVN and CRC labels describe claimed verification or checksum status in the catalog. They do not establish independent test results or emissions compliance.
ST1 catalog variant
The separate entry LC150 1GRFE_E5 89663-60X72_ST1_E2 SV2 6000 p. carries an ST1 label, commonly used for a stage-one performance tune. It also contains the labels E5, E2 SV2 and 6000 p., but the filename alone does not define their exact calibration changes. In particular, the SAP OFF label belongs to the other entry and is not stated for this ST1 file.
Both names associate the identifier with the LC150 and 1GR-FE, but a catalog match does not by itself establish compatibility with every vehicle in that range. The identifier and variant name are useful for distinguishing the files when reviewing an engine-control calibration.
