Product Description:
LS engine owners rejoice! The high price of standalone LS engine management has been Terminated!
Introducing the Terminator X and Terminator X Max—two powerful, affordable engine management systems from Holley designed to deliver true plug-and-play control for most LS engines. Instead of relying on a junkyard ECU with a clunky tuning interface, Terminator X gives you complete engine control, self-learning fuel strategies, and proven race-winning EFI technology—all at an unbeatable value.
The Terminator X system features real-time fuel learning, high-impedance injector drivers, an integrated 1-bar MAP sensor, and four fully programmable inputs and outputs. These I/O channels are perfect for controlling electric fans, boost solenoids, progressive nitrous systems, and more.
Stepping up to Terminator X Max adds even more capability, including support for drive-by-wire throttle bodies and full electronic transmission control—making it an ideal solution for more advanced builds.
Each system comes pre-loaded with base maps for common LS engine combinations, helping you get up and running quickly whether you’re on the street or track. The included 3.5-inch touchscreen handheld controller features an easy-to-use setup wizard, live tuning adjustments, and customizable gauge displays. For advanced users, Holley’s industry-leading EFI software provides full laptop tuning access.
All Terminator X systems utilize the Bosch LSU 4.9 wideband sensor for accurate air/fuel ratio monitoring and precise tuning control. Whether you’re building a budget street car or a boosted race setup, Terminator X delivers the performance, flexibility, and reliability you need—without breaking the bank.
Additionally, Terminator X kits are compatible with a wide range of Holley EFI accessories, including analog-style gauges, shift lights, various expansion modules, and plug-and-play digital dash systems
