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.
