  • 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!

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.
