    Take control of your 302ci Small Block Ford engine in your Fox Body Mustang with Holley EFI Terminator X system. Don't settle for the factory ECU with a cumbersome tuning interface or pre-programmed tuning chip when you can have complete control of your engine, self-learning fuel strategies, and the proven race-winning technology of Holley EFI at an entry price. Terminator X features real-time fuel learn, high impedance injector drivers, an integrated 1 Bar MAP sensor, and four programmable inputs and outputs. The inputs and outputs are ideal for electric fans, boost control solenoids, progressive nitrous control, and more options for your application. Terminator X comes fully loaded with base maps for common Ford V8 engine combinations to get you out of the garage and on the road/track fast. 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 a budget beater or a boosted race car, Terminator X has the features and technology you need to maximize your application.
