      Description


      Take control of your GM Gen V LT4, LT1, L83, or L86 engine with Terminator X! Do not settle for a factory ECU with a cumbersome tuning interface when you can have complete control of your engine, self-learning fuel strategies and the proven, race-winning technology of Holley EFI at a budget-friendly price! Terminator X features real-time fuel learn, an integrated 1bar MAP sensor, and four programmable inputs and outputs. The inputs and outputs are ideal for electric fans, boost control solenoids, progressive nitrous control, and much more. Terminator X comes fully loaded with base maps for common LT engine combinations to get you out of the garage and on the road/track fast. The 3.5" touch screen LCD handheld contains an easy to use calibration wizard as well as tuning and gauge display functions. All Gen V LT Terminator X kits will come with an external Gasoline Direct Injection Controller, which enables the end user to control and tune, factory injectors, GM Gen V LT Variable Valve Timing (VVT), and factory fuel pumps. Also included is Holley EFI's industry-leading, easy to use software suite that allows full laptop access for advanced users. Whether you are building, an LT swapped budget beater or a boosted racecar, Terminator X has the features and technology you need at a price that will not break the bank!

      To identify if your engine is an early or late application, refer to your fuel pressure sensor, located behind the intake manifold. Early sensors have a 4-pin connector, whereas late sensors have a 3-pin connector. This will help you pick which kit you require for your engine.
