Terminator X Max Univ. MPFI Kit w/Trans Control

The Terminator X Max Universal MPFI Kit with Transmission Control represents a comprehensive fuel injection and engine management solution designed for street and performance vehicles requiring a modern, fully integrated EFI conversion. Whether you're retrofitting a carbureted classic, upgrading an older fuel-injected platform, or building a custom engine bay, this universal system eliminates the guesswork of traditional carburetor tuning while delivering reliable cold-start performance, improved fuel economy, and real-time engine diagnostics. Built by Holley, a name synonymous with fuel system innovation since 1903, this kit addresses the core challenge facing engine builders: adapting modern fuel delivery and ignition control to diverse engine platforms without sacrificing tunability or reliability.

The Terminator X Max employs multi-point fuel injection architecture, distributing fuel directly to individual intake ports for precise cylinder-to-cylinder metering and superior atomization compared to single-plane injection or carburetor systems. Integrated transmission control capability means the ECU actively manages shift timing and torque converter lockup, optimizing power delivery across the RPM band while protecting drivetrain components from excessive load shock. The system features self-tuning capability with closed-loop oxygen sensor feedback, automatically compensating for altitude, temperature, and fuel octane variation—critical functions that eliminate the manual jetting and needle-seat adjustments that plague carbureted platforms. Weighing 11.05 lbs and housed in a compact 12.5 x 9.3 x 14.2 inch footprint, the control module integrates ignition timing, fuel pressure regulation, and transmission logic into a single, space-efficient package with extensive wiring harness integration points for universal mounting flexibility.

This system is ideal for engine builders, hot rodders, and restoration shops converting 1960s–1980s muscle cars, street rods, and light-duty trucks to modern EFI standards, as well as custom engine swap applications requiring plug-and-play management without extensive harness fabrication. The universal design accommodates a wide range of engine displacements and intake configurations, from small-block V8s to big-block platforms and even inline-six or V6 applications. Professional installation is recommended to ensure proper sensor integration, fuel system pressure balancing (typically 45–58 PSI for port injection), and transmission solenoid calibration, particularly on vehicles with factory automatic transmissions requiring seamless shift logic. Compatibility extends across most naturally aspirated and moderately boosted applications, though forced-induction tuning may require advanced ECU programming beyond basic setup. This investment transforms outdated fuel delivery into a dependable, fully controllable modern system capable of supporting sustained performance driving, show-quality reliability, and diagnostic capability that traditional carburetors simply cannot provide.
