Chevrolet Performance LS 5.3L Engine Controller Kit

Tailor-Made for Retro Installations

This calibrated controller kit from Chevrolet Performance enables the quicker and easier adaptation of GM's popular 5.3L V-8 for countless hot rod projects. It works with 2005- 2009 5.3L engines and is specially programmed for retrofit installations, with features that make getting the vehicle running easier than if a production 5.3L controller were used. The kit also includes hardware and components that don't typically come with used engines, such as the wiring harness, mass airflow meter and electronic throttle pedal - eliminating the need to source them separately.
Unlike the calibration for regular-production controllers, this specially calibrated 5.3L controller does not engage the cylinder-deactivating Active Fuel Management system that originally came with the engines. A number of other features associated with production-model systems are turned off with the controller, as well, eliminating the possibility of "trouble codes" being set. It is also programmed for easy use with automatic transmissions and includes a SES (service engine soon) LED indicator embedded in the fuse box.
This 5.3L controller system is a true stand-alone system for use in older vehicles, as all that's needed to get a vehicle running with it are power and ground sources, a 58-psi (400 kPa) fuel pump and an electric cooling fan.

The kit includes:

  • Two oxygen sensors
  • Two oxygen sensor mounting bosses (for installation in the exhaust system)
  • Mass airflow meter
  • Mass airflow meter mounting boss (for installation in the air intake system)
  • Throttle pedal assembly (for use with the electronically operated throttle)
  • Specific oil pressure sensor that is compatible with the harness
  • Complete wiring harness with fuse box and necessary cam sensor and MAP sensor jumpers
  • Programmed controller
  • Instruction sheet
  • 12-month/12,000-mile warranty

    This controller is engineered for the following engine codes, which feature 58X ignition systems:
    LC9 (2005-2009)
    LH8 (2008-2009)
    LY5 (2007-2009)
    LMF (2008-2009)
    LMG (2007-2009)
