    Terminator X and 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 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!

    How To Identify GM LS 24 or 58 Tooth Crank Sensors

    1. Proper sensor identification is critical when selecting any LS EFI system - 24x sensors operate at 12v, where as 58x sensors operate at 5v.

    Injector Identification Chart

    • GM used three different injector connector styles on the LS engines. Left - Bosch (EV1) - Center - USCAR (EV6) and Right - Multec 2, which were used in early LS truck 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 full 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.

    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!
