Terminator X And X Max GEN III HEMI Kits

Terminator X powertrain management systems from Holley that offer plug and play control for most Gen III HEMI engines. Why settle for a junkyard ECU with a cumbersome aftermarket tuning interface when you can take complete control of your engine with easy to use self-learning fueling strategies and the proven, race winning technology of Holley EFI.

Terminator X and X Max Features and Benefits

  • Plug and play GEN III HEMI engine control for 2003-2013+ such as the 5.7L, 6.1L and 6.4L engines
  • Plug and Play compatible with Holley EFI accessories – Analog gauges, shift lights, modules, and both 6.86” and 12.3” Pro Dash
  • EV1 or EV6 injector harness included (depending on your injector configuration)
  • High Impedance Injector drivers power Holley EFI and most stock injectors -Injector support chart found in instructions (will not support low impedance injectors)
  • Included Bosch LSU 4.9 wideband O2 sensors for accurate readings and precise tuning control
  • Built in 1bar MAP (manifold absolute pressure) sensor included - For Boosted applications – internal MAP sensor can be disabled and utilize external MAP sensor harness (kit includes a terminated connector for seamless installation)
  • Vacuum hose adapters included - (1/8”, ¼”, and 3/16” sizes)
  • 4 inputs – 12v, Ground, 5v, and frequency for items like pressure sensors, activation triggers, nitrous activation, or trans brake
  • Boost Control – boost vs. time, boost vs. gear, boost vs. RPM, boost vs. speed, and boost safeties
  • Nitrous Control – channels for wet or dry, progressive or non-progressive, rich/lean safeties, and target closed loop AFR (Air/Fuel Ratio)
  • Advanced Tables – ( 4x 1D tables, 1x 1D gear table, 4x 2D table, and 1x 2D gear tables) for nearly unlimited table configuration options
  • On-board diagnostic LEDS - ECU power, engine run, TPS calibration, cam signal, and more! Identify critical engine parameters at a glance
  • 3.5” touchscreen handheld included - Internal data-logging, custom gauge display, and calibration wizard allow quick building bases tunes for any Domestic V8 engine
  • Compact ECU (Engine Control Unit) – At only 7.45” x 4.1” x 1.66” the compact packaging allows mounting virtually anywhere (XMAX ECU = 9.6” x 4.1” x 1.66”). REMINDER: diagnostic LED’s must face up!
  • FREE EFI Tuning software – For compete control of your Terminator X power plant

Diagnostic LED's

  • 8 Built-in multi-color diagnostic LED's allow you to quickly identify a variety of potential system issues, such as a failed TPS Autoset - faulty crank or cam sensors, or potential oxygen sensor issues!
  • 1. ECU Power - Green = ON
  • 2. Engine Running - Green = Running - Yellow = No RPM
  • 3. Wideband Status - Blue = Too Hot, Too Cold, Slow Warmup, or Uncalibrated, Green = OK!, Red = Sensor Failure, Yellow = Sensor Heating, Off = Sensor Disabled.
  • 4. TPS Calibration - Green - Calibrated, Red = Calibration Error, Cyan = DBW Pedal Calibration Error, Purple = DBW TB Calibration Error.
  • 5. Undefined - Future Use!
  • 6. Crank Signal - Green = Tooth Detected, below crank to run RPM (400RPM), Blue = Gap Detected, below crank to run RPM (400RPM), Red = Crank Error Detected, Off - Synced Properly.
  • 7. Cam Signal - Green = Tooth Detected, below crank to run RPM (400RPM), Blue = Gap Detected, below crank to run RPM (400RPM), Red = Cam Error Detected, Off - Synced Properly.
  • 8. Undefined - Future Use!

Troubleshooting at a Glance!

Terminator X ECU Connections

  • J1A - Main Harness Connector - This connector is primarily an “Input” connector. It contains all the sensor inputs and wide band oxygen sensor control.
  • J1B - Main Harness Connector - The second connector is the “J1B” connector (26 pin). This connector is the “output” connector. It has 8 injector outputs and outputs for other devices.
  • MAP Sensor - used on N/A applications, connect directly to left manifold vacuum port on the intake manifold.
  • Main Power - Connects to the Main Power Harness, these two wires MUST be wired directly to the Battery Terminals.

Handheld Boost Control!

  • The Terminator X system integrates boost control functionality into the handheld, allowing you to easily change timing and AFR offset without needing a Laptop!
  • For the advanced user, the Terminator X Software contains a robust boost control system, with Dome Control, Boost By Time/Gear/RPM/Speed, and built in Boost Safeties.

Boost Control at your Fingers Tips

Bottle Fed Power Management!

  • If nitrous oxide is your power adder of choice, the Terminator X system put nitrous control in your hands!
  • Through the handheld you have the power to set Min/Max RPM for Nitrous Activation, retard or advance timing, set Target AFR, and even build custom progressive curves for both Nitrous Percentage, and Ignition Timing.

Nitrous Control made easy!
