19369381 - Chevrolet Performance LSA/556 Controller Kit - Contains Pre-Programmed ECU, Harness, Sensors

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.
