The Chevrolet Performance 19540147 LS2/LS3 Engine Controller Kit is a plug-and-play, stand-alone engine management system for installing a Chevrolet Performance LS3 crate engine into older vehicles. The kit ships with a pre-programmed engine control module calibrated specifically for retrofit applications, eliminating many of the diagnostic features required in late-model production vehicles that would otherwise trigger trouble codes during a swap. All hardware needed to plug into the engine and start it is included, requiring only power and ground sources, a high-pressure fuel pump, and an electric cooling fan to complete the installation. Maximum engine speed is 6,600 rpm. Supersedes Part Number 19354328.
