TERMINATOR X MAX LT GDI LATE DBW

The Holley EFI Terminator X Max GM Gen V LT Late Direct Injection Kit (MPN: 550-1621) provides complete control for GM Gen V LT1, L83, or L86 engines. It features real-time fuel learn, an integrated 1bar MAP sensor, and four programmable inputs and outputs for accessories like electric fans or boost control. The kit includes an external Gasoline Direct Injection Controller, enabling control and tuning of factory injectors, GM Gen V LT Variable Valve Timing (VVT), and factory fuel pumps. It also comes with a 3.5" touch screen LCD handheld for calibration and tuning, and Holley EFI's software suite for advanced laptop access. This system is ideal for swapping late model GM Gen V LT engines into vintage vehicles.

This specific kit is designed for "late" applications, which can be identified by a 3-pin connector on the fuel pressure sensor located behind the intake manifold (early sensors have a 4-pin connector). The included engine harness plugs directly into the factory LT DI injector sub-harness, supporting OEM injectors. The unit also features Genuine Bosch LSU 4.9 Wideband Control and on-board diagnostic LEDs for quick issue identification.
