Engine Management System Terminator X

The Engine Management System Terminator X is a professional-grade engine control unit designed for serious enthusiasts and performance builders who demand precision fuel and ignition management. Built by Holley, a trusted name in engine management for over seven decades, this system replaces outdated factory electronics with a fully programmable platform that gives you complete authority over your engine's operation.

Whether you're tuning a carbureted classic, managing a fuel-injected stroker, or dialing in a turbocharged application, the Terminator X delivers the flexibility and real-time control that separates magazine-quality builds from backyard guesses. This system features a robust processor core capable of monitoring and adjusting fuel delivery, ignition timing, and auxiliary functions across a wide operating range without hesitation or latency.

The compact unit measures 11.3 x 7.6 x 12.3 inches and weighs approximately 9 lbs, making it ideal for tight engine bays where space is at a premium—critical for retrofit applications in vintage vehicles or custom frame-up restorations. User-friendly software allows you to log data, adjust parameters on the fly, and diagnose issues without dealer dependency.
