Terminator X Max MPFI w/Trans & DBW Control

The Terminator X Max MPFI w/Trans & DBW Control by HOLLEY represents the gold standard in modern engine management for street, strip, and competition vehicles. This advanced fuel injection and transmission control system is engineered for builders and tuners who demand precision, reliability, and real-time adaptability in high-performance applications. Whether you're tuning a naturally aspirated engine, forced induction platform, or hybrid combination, the Terminator X Max delivers the computational power and sensor integration necessary to maximize power while maintaining drivability and fuel efficiency.

This system integrates multi-point fuel injection (MPFI) control with fully integrated transmission management and drive-by-wire (DBW) throttle authority, eliminating the need for separate ECUs and reducing wiring complexity significantly. The Terminator X Max features onboard closed-loop oxygen sensor feedback, real-time knock detection, and adaptive fuel and ignition mapping that responds to changing load conditions, ambient temperature, and fuel quality. The integrated DBW control enables smooth throttle modulation, cruise control integration, and launch control for consistent off-the-line performance—critical advantages when tuning modern drivetrains with electronic transmissions or automatics requiring precise torque management.

Professional engine builders, diesel and gasoline tuners, and street rodders benefit most from the Terminator X Max system's flexibility and scalability across engine sizes and fuel types. Installation requires basic mechanical knowledge and familiarity with wiring harness routing; Holley provides detailed calibration software and extensive tuning support through their ecosystem. This control module is compatible with a wide range of LS, small-block Chevy, big-block, and aftermarket engine platforms, making it an investment that scales with your build progression and evolves through software updates as your performance goals change.
