- 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
- 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!
Injector Identification Chart
- OEM's used three different injector connector styles on the factory injectors. Left - Bosch (EV1) commonly found on late 80's early 90's Engines - Center - USCAR (EV6) and Right - Multec 2, which were used in early LS truck engines.

Terminator X Max 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 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.
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!
