Toyota Prado 150 89663-60F91 Engine ECU Firmware
Catalog details for Toyota Prado 150 89663-60F91 firmware, listed for the 2.7L 2TR engine and a 992 KB flash image.
89663-60F91 is an engine-control calibration identifier associated in this catalog with a 2010 Toyota Land Cruiser Prado 150 and its 2.7-liter 2TR petrol engine. The named flash image belongs to the engine ECU software family, which manages engine operation rather than a body or infotainment system.
The engine ECU uses sensor inputs to control functions such as fuel delivery and ignition timing. These controls affect starting, idle quality, throttle response, fuel consumption and emissions. The catalog identifier alone does not establish which of those settings, if any, changed in this particular calibration.
