Terminator X Engine Management System

The Holley 550-909 Terminator X Engine Management System provides advanced control for GM LS1/LS6 engines featuring a 24x crank reluctor and EV6 (USCAR) injectors. This system empowers users with self-learning fuel strategies and the race-winning technology of Holley EFI at an accessible price point. Key features include real-time fuel map learning, which removes the guesswork from tuning your base fuel table, and high impedance injector drivers capable of safely powering most stock LS injectors, as well as those from Injector Dynamics, Deatschwerks, FIC, and Holley. The system is equipped with an integrated 1-bar Bosch MAP sensor, perfect for naturally aspirated or nitrous applications. For boosted setups, a harness connector allows for the use of external 2, 3, 4, or 5-bar MAP sensors. The Terminator X system offers significant expandability with 4 programmable inputs and 4 programmable outputs, ideal for controlling electric fans, boost control solenoids, progressive nitrous activation, and more. It supports sophisticated boost control strategies (Boost vs. Time, Gear, RPM, Speed) and single-channel nitrous control (Wet or Dry, Progressive or Non-Progressive) with various safety features. The system also includes advanced table capabilities for custom tuning, such as flex fuel sensor offset tables or custom fuel/oil pressure safeties. Included with the system is a 3.5" color touchscreen LCD handheld that simplifies tuning with a calibration wizard and provides fully customizable gauge displays and internal data logging. The ECU itself is compact for versatile mounting options. Base maps for common LS engine combinations are pre-loaded to get your vehicle running quickly. The system is compatible with Holley EFI accessories like gauges, shift lights, and digital dashes. A free laptop EFI tuning software suite is also provided for advanced users seeking complete control.
