Take Control of Gen V LT Swaps with Holley Terminator X!

Designed for those swapping GM's latest small-block V8 engine, the Generation V LT-series packs a lot of cutting-edge technology features into a high-performance package. Loaded with base mapping for popular LT engine combos, Terminator X is compatible with the LT1, L83 5.3L, and L86 6.2L truck engines. Pre-loaded with base mapping for popular engine setups, Terminator X will have your project running in no time!

This controller is engineered for late DI GM LT engines with controls for either a 4L60E or 4L80E automatic transmission. There are NO functions for drive-by-wire style throttle bodies.

Features

• Simple Plug-and-Play engine controller for GM Gen V LT series engines with support for Direct Injection (DI) and Variable Valve Timing (VVT)
  • Included engine harness will plug directly into the GM LT DI injector sub-harness
• Transmission Control for GM 4L60E and 4L80E automatics 
• LCD 3 1/2 inch touchscreen provides easy base tuning with the calibration wizard that is able to show gauge displays and data logging.
• Real-Time Self-Learning fuel maps require no complicated tuning knowledge (Holley EFI software suite is included for advanced users with laptops)
• On-board Multi-Color LED Diagnostic allows quick troubleshooting on critical issues for ECU Power, Engine Running, Wideband Status, TPS Calibration, Crank Signal, Cam Signal, VVT Status, Pump Control, and DI injectors
• Built-in 1bar MAP Sensor with 1/8, 1/4, & 3/16 in. vacuum hose adapters included. For boosted applications, the internal sensor can be disabled to run an external LT style MAP sensor (not included) with the included terminated harness and connector.
• 4 Inputs - 12-volt, Ground, 5-volt, and Frequency can be used for activation triggers, trans brake, and to add extra pressure sensors.
• 4 Outputs - Ground and PWM can be used for electric fans, boost control, nitrous control,  idle air control kit, and many more accessories. 
• Boost Controls - Ability to control boost vs time, boost vs. gear, boost vs. RPM, boost vs. speed, boost vs. safeties
• Nitrous Controls - Single Channel of Wet or Dry, Progressive or Non-Progressive, rich/lean safeties, and target closed-loop AFR
• Advance Tables - 4x 1D Table, 1x 1D Gear Table, 4x 2D Table, 1x 2D per Gear Table.  Can be used for custom tables for flex fuel sensor, fuel pressure safety, or oil pressure safety.
• Bosch LSU 4.9 Wideband for precision reading and tuning control (will not function with LSU 4.2 oxygen sensors)
• Holley EFI Accessories are mostly compatible (analog-style gauges, shift lights, and others.)

Notes:

• To determine if your engine is an early or late model application, examine the fuel pressure sensor behind the intake manifold. If the sensor has a 4-pin connecter it is the early model, if it has a 3-pin connecter it is a late style. An image is shown to help identify which kit you will need.
• Camshafts with oversized fuel pump lobes are NOT supported
• Can only control 4L60E and 4L80E automatic transmission, 6-speed, 8-speed, and 10-speed automatic transmissions are NOT supported.
