Description
Advanced Fuel Injection System. The Holley EFI Terminator X Max Fuel Injection System with Drive-By-Wire Throttle Body Control for EV1 Fuel Injectors is engineered to provide precise fuel management for Chrysler Gen III HEMI engines. Designed for seamless integration with factory DBW throttle bodies, this system enables real-time fuel learning and sophisticated tuning options suited for performance applications. It delivers improved engine performance and reliability by accurately controlling fuel delivery and enabling extensive boost and nitrous management.
Construction and Appearance. The system features a compact ECU with robust construction to withstand automotive environments. The ECU enclosure measures 7.45 by 4.1 by 1.66 inches, designed for versatile mounting locations with diagnostic LEDs oriented upwards for easy visibility. The included touchscreen handheld controller offers a modern, durable display housed in a ruggedized casing for handheld use, while all sensors and connectors are high-quality OEM-spec components ensuring durability and fitment compatibility.
Installation. Installation of the Terminator X Max is designed to be plug-and-play for the specified HEMI engines, minimizing the need for modifications. Harnesses and adapters facilitating setup are included, providing a streamlined installation suitable for professional or experienced DIY enthusiasts.
Application. This EFI system fits Chrysler Gen III HEMI engines from 2003 to 2013+ with factory drive-by-wire throttle bodies and no variable valve timing (VVT). It supports 5.7L, 6.1L, and 6.4L V8 engines but is not recommended for use with 6.2L HEMI engines. The system is intended for use on non-emissions-controlled vehicles, making it suitable for off-road and racing applications but not compliant with emissions regulations for street use.
