Engine Control Computer

The Lexus 89666-30361 is a genuine OEM replacement engine control computer (ECU) designed specifically for the 2006 Lexus GS300. This unit is offered with a unique programming service that eliminates the need for costly dealer programming or locksmith intervention. By sending your original ECU, your VIN and key data will be transferred to the replacement unit, allowing for a plug-and-play installation. The entire process typically takes 5 to 7 business days, including shipping times. Module Mechanics tests these pre-owned units and includes a 2-year warranty, with an option to extend to 5 years. While the part number received may vary slightly, it will be fully compatible. The service can often recover data even from units with water or physical damage, provided they were able to start the vehicle at one point. Common symptoms of a failing ECU include rough idle, misfires, poor acceleration, failure to start, and transmission shifting problems.
