  • 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!
     

How To Identify GM LS 24 or 58 Tooth Crank Sensors

  • Black crank sensors will be found on 24x (tooth) LS engines.
  • Gray crank sensors will be found on 58x (tooth) LS engines.

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

Injector Identification Chart

GM used three different injector connector styles on the LS engines:

  • 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 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. Is 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.
      

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 “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 – Connections 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.
     

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.
