    This Engine Controller Kit is exactly what you need to power your brand new LS3 crate engine from GM. Designed for a simple plug & play installation, the engine control module is the brain of your Gen III/IV LS-series engine. GM Performance controllers are uniquely calibrated for installation in older vehicles and means that many features for late-model vehicles are turned off because they simply are not needed on your classic. This is a true standalone system that only requires the use of power and ground sources as well as a high pressure fuel pump and an electric cooling fan. This kit include all of the components required as well as detailed instructions to get your LS engine running.

    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 (when needed) Complete wiring harness with fuse box and necessary cam sensor and MAP sensor jumpers Fuel pump power module Fuel pressure sensor Programmed controller Instruction sheet.
