Ford Godzilla 7.3L engine owners, your wait is over. Holley has announced their new engine-specific multi-point fuel injection kit for your amazing engine. Let's start by going over exactly what a "Terminator X" is and then we can get into the specifics of why this is hands-down the best choice for your 7.3L Godzilla Engine.

What's Terminator X?

Holley's Terminator X family of EFI Systems are standalone engine management systems that closely replicate some of Holley's most advanced engine management systems but at a much more budget-friendly price. This PDF gives a highly detailed comparison of the Terminator X and X Max to engines built using the Holley HP and Dominator ECUs. To summarize, Holley was able to leave out some features found to be less-necessary by the majority of users and, in doing do, slash the price of a full-featured EFI System by half.  If you're switching your carbureted engine to multi-point EFI or are swapping a fuel-injected engine into your ride and need to stay on a budget, this is the EFI system for you.

Here are some of the features that are included in each Terminator X kit:

• Eight High-Impedance Injector Drivers
• Configuration, monitoring and data logging via included 3.5-inch touchscreen LCD display
• Configuration and monitoring via Terminator PC software (free download) and optional CAN-to-USB adapter cable
• Four configurable inputs and outputs
• Boost Control*
• Single-Stage Progressive Nitrous Control*
• Staging Assist*
• Transmission Controls**
• Drive-By-Wire Control**

• *Requires hardware not included with Terminator X system to implement
• **X Max Version Only

Different Terminator X EFI Systems For Different Applications

Yes, there are quite a few different Terminator X EFI System--nearly 100 with more on the way.  All Terminator X systems include either a Terminator X or Terminator X Max ECU. The Terminator X Max ECU provides connectivity for transmission control and drive-by-wire harnesses and is included only in those kits that require one or both of these features. Both ECUs include an on-board 1-BAR MAP sensor or you can add an external MAP sensor for boosted applications. On-Board Diagnostic LEDs display the status of ECU Power, Engine Run, Wideband Status, TPS Calibration, Crank Signal, and Cam Signal

In addition to the ECU the kit all Terminator X / X-Max systems include the following:

• ECU Power Harness
• Application-Specific Main Harness
• 3.5-inch Touchscreen LCD Display with Setup Wizard app
• Custom 4-input / 4-output harness pre-configured for two Electric Fans, A/C Kick, and A/C Shutdown
• Bosch LSU 4.9 Wideband O2 Sensor

Unique To The Terminator X MPFI Kit for Ford Godzilla 7.3L Engine

Your Choice of Coil Connectors!

Holley only offers their Terminator X MPFI Kit for Ford Godzilla 7.3L Engine with built-in connectors for the OE Ford Smart Coils. But a lot of folks are running this engine with FuelTech's IGN1A Smart Coils. To do that you've got three choices: Swap out the connectors yourself (painful!), buy the optional Holley EFI Godzilla Main Haress with FuelTech connectors (added expense!) or, make the smart choice: Just buy the your Terminator X Max kit for your 7.3L Ford from us and let us know you want to run FuelTech coils. We'll swap out the OE-style main harness and coil drivers for the main harness with the FuelTech connectors--at no additional cost!
