If you are thinking about installing a Terminator X in your LS engine swapped vehicle, this how-to is for you!
These units make such good sense because they offer Plug and Play Standalone Engine Management at a budget price, and are compatible with most modern domestic V8 Engines.
- Terminator X works on any LS-based engine including common 4.8, 5.3, or 6.0 truck engines (often referred to as LQ4, lQ9, LM7, L33, etc.)
Terminator X and Terminator X Max
Holley offers two powertrain management systems that feature plug and play control for most domestic V8 engines starting at just $999.
Why settle for a junkyard or factory ECU with a cumbersome aftermarket tuning interface when you can get complete control of your engine, self-learning fuel strategies, and the proven, race-winning technology of Holley EFI for under $1,000…
Terminator X and Terminator X Max Features and Benefits
- Plug and play Domestic V8 engine control
- Drive-by Wire Throttle Body Control (Terminator X Max Only)
- Transmission Control (Terminator X Max Only)
- Genuine Bosch LSU 4.9 Wideband Control (Will not work with LSU 4.2 Oxygen Sensors)
- On-Board Diagnostic LEDS for: ECU Power – Engine Run – Wideband Status – TPS Calibration – Crank Signal – Cam Signal. Allow you to identify any Critical engine issues at a glance
- Built in 1bar MAP Sensor, vacuum hose adapters included (1/8th – ¼ and 3/16ths) – or for Boosted applications, you can disable the internal MAP sensor, and utilize an external MAP Sensor, the harness comes with the connector terminated, making the installation a snap.
- 4 Inputs – 12v, Ground, 5v, and Frequency, for things such as additional pressure sensors, or activation triggers for nitrous activation, or a trans brake (Fuel and Oil Pressure Inputs are pre-terminated)
- 4 Outputs – Ground, PWM – , for accessories such as; fans, boost control, nitrous control, IAC Kit, and More
- Boost Control – Boost vs Time, Boost vs Gear, Boost vs RPM, Boost vs Speed, Boost Safeties
- Nitrous Control – Single Channel of Wet or Dry, Progressive or Non-Progressive, Rich/Lean Safeties, and target Closed Loop AFR
- Advanced Tables – 4x 1D Tables, 1x 1D per Gear Table, 4x 2D Tables, 1x 2D per Gear Table
- Integrated Datalogging to the 3.5” Handheld SD Card
- Free EFI Tuning Software for complete control of your Terminator X power plant
Diagnostic LEDs Offer Troubleshooting at a Glance
8 Built-in multi-color diagnostic LEDs 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!
- ECU Power – Green = ON
- Engine Running – Green = Running – Yellow = No RPM
- Wideband Status – Blue = Too Hot, Too Cold, Slow Warmup, or Uncalibrated, Green = OK!, Red = Sensor Failure, Yellow = Sensor Heating, Off = Sensor Disabled.
- TPS Calibration – Green – Calibrated, Red = Calibration Error, Cyan = DBW Pedal Calibration Error, Purple = DBW TB Calibration Error.
- Undefined – Future Use!
- 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.
- 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.
- Undefined – Future Use!
How To Identify GM LS 24 or 58 Tooth Crank Sensors
Proper sensor identification is critical when selecting any LS EFI system.
- 24x sensors operate at 12v. Black.
- 58x sensors operate at 5v. Gray.
How To Identify GM LS Injector Connectors
GM used three different injector connector styles on the LS engines.
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.

- 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 right 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.
- J3 – Connection point for the Drive-By-Wire harness.
- J4 – Connection point for the Transmission harness.
