Ready for standalone engine management at a budget price? Take control of your GM Gen V LT1, L83, or L86 engine with a Holley Terminator X Max GM Gen V LT direct injection kit! They're available to fit early non-WT drive-by-wire engines, as well as late WT drive-by-wire engines.

Terminator X and X Max features and benefits:

* Plug-and-play GM Gen V LT engine control, including GDI and VVT support
* Ideal for swapping late model GM Gen V LT engines into vintage vehicles
* 3.5 in. hand-held gets your engine running in no time with a step-by-step calibration wizard
* GM LS and LT drive-by wire throttle body control (Terminator X Max only)
* GM 4L60 and 4L80 transmission control (Terminator X Max only)
* Included engine harness plugs directly into the factory LT DI injector sub harness
* OEM Injectors supported, with part numbers provided in the handheld wizard or software
* 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 – VVT Status – Pump Control – and DI Injectors. This allows you to identify any critical engine issues at a glance
* Built-in 1 bar MAP sensor, vacuum hose adapters included (1/8th, 1/4 and 3/16ths); or for Boosted applications, you can disable the internal MAP sensor, and utilize an external LT MAP sensor. The harness comes with the connector terminated, making the installation a snap
* 4 inputs: 12 V, Ground, 5 V, 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
* Integrated data logging to the 3.5 in. hand-held SD card
* Free EFI tuning software for complete control of your Terminator X powerplant

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 eight 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.
