Terminator X MPFI Kit GM LS Early Truck

The Holley Terminator X MPFI Kit for GM LS Early Truck engines is a complete engine control module and wiring harness solution designed to bring modern fuel injection management to early LS-based truck platforms. This kit is ideal for engine builders, restoration shops, and experienced enthusiasts undertaking GM LS engine swaps into early trucks where original fuel systems and management are being replaced.

This kit includes the Terminator X ECU, a 24x reluctor wheel trigger system, and all necessary harness components for seamless integration into applications where factory EFI controllers are inadequate or unavailable. The 24x reluctor wheel configuration provides precise crankshaft position feedback, critical for accurate fuel injection and ignition timing across the full operating range. This level of control enables tuners to dial in optimal air-fuel ratios and spark advance curves without the constraints of OEM programming.

Holley's Terminator X platform has become the standard in the LS swap and engine control retrofit segment, trusted by builders across drag racing, street rod, and truck modification communities. It's particularly suited for applications using standalone fuel injection on carbureted or TPI-equipped platforms being modernized for reliability and tunability. The modular design allows for easy installation and customization, making it a versatile choice for various performance applications.
