Welcome to the LS Controller Kit page. Here, you’ll find the controller kit you need to get power into your project car. From the accelerator pedal to the fuse panel, each kit comes with all the sensors, cables, and connectors you need.

All pre-wired and pre–labeled. And it’s all easy to install. So go ahead. Harness the power.

5.3L Controller System

5.3L Controller System

Our 5.3 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) 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 specific oil pressure sensor that is compatible with the harness A complete wiring harness with fuse box and necessary cam sensor and MAP sensor jumpers The programmed controller An instruction sheet     The controller is engineered for the following 5.3L engine codes, which feature 58X ignition systems: LC9 (2005-2009) LH8 (2008-2009) LY5 (2007-2009) LMF (2008-2009) LMG (2007-2009)

LSA Controller System

LSA Controller System

Like Chevrolet Performance's other controller kits, the LSA 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.
