Holley Terminator X MAX engine management systems let you take control of your domestic V8 engine. They give you complete charge of your engine and self-learning fuel strategies, along with the proven, race-winning technology of Holley EFI—all at a budget-friendly price! Every MPFI Terminator X MAX features real-time fuel learn, high-impedance injector drivers, an integrated one-bar MAP sensor—and four programmable inputs and outputs, ideal for electric fans, boost control solenoids, progressive nitrous control, and much more. Also, Holley offers the X MAX systems with either or both drive-by-wire (DBW) throttle body control or transmission control. All kits come fully loaded with base maps for common domestic V8 engine combinations to get you out of the garage and onto the road or track fast. Order the model recommended for your vehicle application.

• Holley EFI industry-leading, easy-to-use software suite allows full laptop access for advanced users
• Real-time fuel map learn—takes the guesswork out of tuning your base fuel table

• Advanced tables can be used for any custom tables
• On-board diagnostic LEDs allow you to identify any critical engine issues at a glance
• The compact ECU size allows you to mount it virtually anywhere. Remember, diagnostic LEDs must face up!
