Overview

The Holley 550-1431 Terminator X MPFI Controller Kit is designed for seamless integration with the 7.3L Ford Godzilla engine, offering easy installation and hassle-free setup without extensive modifications. It includes pre-configured base calibrations for OEM VVT and oil pump control, accessible via the free Terminator X Software and Handheld Wizard. A Godzilla Crank Sensor Module is included for in-line connection with the factory crank sensor. The kit provides customizable tuning parameters, supports drive-by-wire (DBW) systems with specific OEM throttle bodies (JL3E-9F991-AA) and pedals (BR3Z-9F836-D), and features real-time fuel map learning. The system utilizes a Bosch LSU 4.9 wideband sensor for accurate AFR readings, high-impedance injector drivers, and an on-board 1BAR MAP sensor suitable for N/A or Nitrous applications (2+BAR systems recommended for boosted applications). It also includes various inputs and outputs for accessories, boost control, and nitrous control, along with advanced tables for custom configurations. On-board diagnostic LEDs allow for quick identification of engine issues, and a 3.5-inch touchscreen handheld provides a calibration wizard, data-logging, and customizable gauge displays. The compact ECU size allows for flexible mounting, and it is compatible with other Holley EFI accessories like analog style gauges, EGT module, and digital dashes. The free EFI Tuning Software offers complete control.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
