What's the 2006 Lexus gs300 ecu location?

The 2006 Lexus GS300 ECU location is located in the engine compartment near the firewall. An engine control unit (ECU), also commonly called an engine control module (ECM) is a type of electronic control unit that controls a series of actuators on an internal combustion engine to ensure optimal engine performance. It does this by reading values from a multitude of sensors within the engine bay. It then interprets the data using multidimensional performance maps (called lookup tables) and adjusting the engine actuators. If the ECU has any issues, it may throw off the timing and fuel settings of the engine, which can negatively affect performance. A faulty ECU may cause the vehicle to experience a reduction in fuel efficiency, power, acceleration.
