Terminator X Max MPFI System GM LS 24X/1X

The Terminator X Max MPFI System GM LS 24X/1X from Holley represents the gold standard in modern engine management for LS platform builds. Designed for serious enthusiasts and professional shops, this fuel injection and ignition control system delivers precise fuel and spark timing management that transforms naturally aspirated or forced-induction LS engines into reliable, responsive powerplants. Whether you're building a street cruiser, high-performance truck, or race engine, the Terminator X Max handles the complexity of modern combustion tuning so you can focus on maximizing horsepower and drivability.

At its core, the Terminator X Max integrates standalone fuel injection and ignition control in a single, user-friendly ECU platform engineered specifically for GM LS engines running 24X/1X crankshaft sensor configurations. This system reads your engine's CAN-bus data, manages sequential multiport fuel injection, and fires individual ignition coils with millisecond precision, eliminating the need for compromised stock PCM tuning. The 24X/1X sensor interpretation means you get bulletproof synchronization on LS1, LS2, LS3, LS7, and LSX variants; advanced knock detection and correction protect your build from detonation; and real-time datalogging via USB allows you to dial in fuel curves, timing maps, and fuel pressure strategies with surgical accuracy on the dyno or street.

Professional engine builders and weekend warriors rely on the Terminator X Max for engine swaps, carbureted-to-EFI conversions, and radical LS builds where factory PCM limitations don't cut it. The system is fully compatible with naturally aspirated, supercharged, turbocharged, and nitrous-assisted LS engines, and integrates seamlessly with modern auxiliary systems including transmission control, idle air control, and data acquisition modules. Installation requires basic wiring knowledge and familiarity with engine bay routing; Holley provides comprehensive documentation and customer support to ensure proper calibration and setup for your specific application.
