The Terminator X Ford MPFI Kit by Holley delivers a complete engine control and fuel management system designed specifically for big-block and small-block Ford engines. This comprehensive kit includes an ECU (Engine Control Module), a 3.5-inch color touchscreen interface, and a complete wiring harness—everything required to convert carbureted Ford engines to modern multiport fuel injection or to upgrade existing MPFI systems with precise electronic control. The integrated touchscreen provides real-time engine diagnostics, tuning parameters, and data logging directly from the engine bay or shop bench.
Built-in fuel and ignition mapping allows fine-tuning of air-fuel ratios, spark advance, and idle characteristics across the entire RPM range—critical for extracting maximum power and efficiency from carbureted conversions or aggressive small-block and big-block Ford builds. The 3.5-inch display offers intuitive menu navigation for on-the-fly adjustments, live cylinder data, and engine protection features. The included wiring harness eliminates guesswork during installation and is designed to integrate with Ford engine bays without extensive fabrication, reducing installation time and complexity for both bolt-on conversions and ground-up restorations.
This kit is ideal for hot rod builders, restomodders, and performance enthusiasts upgrading classic or modern Ford engines to independent electronic fuel and ignition management. Whether converting a carbureted classic to MPFI for reliability, improving cold-start performance on an existing FI engine, or building a high-output street or strip motor, the Terminator X system provides the control platform needed for repeatable tuning and data acquisition without external standalone ECU complexity.
Holley's Terminator X line is recognized among Ford engine builders for straightforward installation and user-friendly tuning interfaces that reduce development time while maintaining the precision required for fuel injection optimization on both street and competition engines.
