Holley EFI Kit Terminator X 4.6L/5.4L 2V/4V Ford Modular Motor

Take control of your 4.6L or 5.4L 2V/4V Modular Ford Motor’s performance with a Holley Terminator X EFI Kit! This kit features a plug-and-play engine control unit (ECU) pre-loaded with a variety of base calibrations. Matched with the kit’s real-time fuel learning, integrated 1bar MAP sensor, and Bosch LSU 4.9 wideband O2 sensors, these calibrations offer a consistently perfect air/fuel ratio for top-notch performance in any setting. If your engine requires a more personal touch, you can also create your own tunes on a laptop (not included) using the included EFI tuning software and the USB dongle.

In addition to the seemingly limitless tuning capabilities, this ECU also has 4 programmable inputs: a 12v, ground, 5v, and frequency. These are perfect for electric fans, boost control solenoids, progressive nitrous control, and other accessories necessary to support high-performance engine modifications. The on-board diagnostic LEDs help identify critical engine parameters at a glance, letting you keep an eye on ECU power, engine run, TPS calibration, and more. This compact ECU kit is made in the USA and comes with either an EV1 or EV6-style injector harness to match the rest of your EFI system.
