The Holley Dominator EFI Kit for LS2 with transmission controller and drive-by-wire is a complete engine management solution purpose-built for GM LS-series engine swaps and retrofits. Designed for enthusiasts and professional builders working with LS2 powerplants, this kit eliminates the complexity of standalone engine control by providing factory-level integration with modern drivability, fuel efficiency, and emissions control.
This comprehensive kit includes the Dominator ECU (Engine Control Module), integrated wiring harness, and transmission control harness that work in concert to manage fuel injection timing, ignition sequencing, and automatic transmission operation. The drive-by-wire capability replaces mechanical throttle cables with electronic control, offering faster throttle response and integration with modern auxiliary systems.
Professional mechanics, experienced hot rodders, and serious engine swap enthusiasts will benefit from the precision tuning and reliability expected in modern performance builds. The modular design accommodates various LS2 configurations and mounting scenarios, making it an ideal choice for converting classic muscle cars or upgrading existing LS2 installations.
