Standalone Engine Management Systems
Holley EFI has delivered the Terminator X and Terminator X Max standalone engine management systems (EMS) for swappers to take full control of their fuel-injected or multi-point fuel injected (MPFI) engines. Terminator X systems design is a simple plug-and-play unit incorporating self-learning technologies without needing any tuning interfaces, which is often required when using a factory power-train control module (PCM). Terminator X kits offer engine control, while Terminator X Max kits offer both engine and transmission control. Power adders such as nitrous and boost can easily be handled with custom settings and features, making these Terminator X kits ideal street and strip ECMs.
