Like Chevrolet Performance's other controller kits, the LS9 Controller Kit is specially calibrated for installation in older vehicles. That means many of the features required for late-model production vehicles are “turned off,” because they're not required in older cars and trucks – eliminating the possibility of triggering a diagnostic trouble code that could possibly affect performance or require additional third-party tuning.

This inclusive kit delivers all the components required to plug into the engine and get it running – from the controller itself and the accompanying wire harness to the mass airflow sensor, oxygen sensors and even a throttle pedal assembly to match the electronic throttle. Contents include:

  • Two oxygen sensors
  • Two oxygen sensor mounting bosses (for installation in the exhaust system)
  • A mass airflow meter
  • A mass airflow meter mounting boss (for installation in the air intake system)
  • A throttle pedal assembly (for use with the electronically operated throttle)
  • A complete wiring harness with fuse box
  • The programmed controller
  • An instruction sheet

It is a true stand-alone system. All that's needed to get a vehicle running with it are power and ground sources, a high-pressure fuel pump and an electric cooling fan. It is also programmed for easy use with Chevrolet Performance's automatic transmissions and includes a SES (service engine soon) LED indicator embedded in the fuse box.

*Note - This controller will not function in a production vehicle unless all kit components are used and will not operate production gauges.
