HP ECU & Harness LS1/LS6 NTK

The Holley HP ECU & Harness LS1/LS6 NTK is a complete engine control module and wiring harness kit designed specifically for LS1 and LS6 engines in GM LS-series applications. This kit is ideal for builders looking to install LS powerplants into street cars, race vehicles, or restomod projects, simplifying the process by providing all necessary components in one package.

This integrated fuel injection management system includes the Holley HP EFI engine control module, a factory-style wiring harness, an NTK oxygen sensor, and a 24-tooth reluctor wheel for precise engine control. The 24-tooth configuration is the factory standard for LS engines, ensuring reliable signal recognition and timing accuracy. The oxygen sensor allows for closed-loop fuel correction, optimizing performance and meeting emissions standards.

This kit is purpose-built for LS engine swaps into various platforms, including truck beds, classic muscle cars, kit cars, and race chassis, where modern fuel injection and ignition systems are desired. By eliminating the need to source individual components, this system reduces installation complexity while maintaining the reliability of OEM-sourced sensor technology.
