Holley expands its Holley EFI’s plug-and-play Terminator X and Terminator X Max electronic fuel-injections systems, which give you self-learning fuel strategies, complete control of your LS engine, and the proven technology of Holley EFI at a budget-friendly price. Now available are Terminator X systems for LS1 engines with EV6, LS2/LS3s systems for late-model trucks, and Terminator X Max systems for numerous drive-by-wire/multi-point-fuel-injection applications with electronic transmission control.

Compatible with a wide range of LS engines, Terminator X and Terminator X Max systems come packed with base maps for common engine combinations to get you on the road or the race track in no time. They feature real-time fuel learning, an integrated 1-bar MAP sensor, high-impedance injector drivers, and four fully programmable inputs and outputs. The inputs (12-volt, 5-volt, frequency, and ground) are perfect for additional pressure sensors and activation triggers for nitrous and trans-brakes, and the outputs are ideal for boost-control solenoids, progressive nitrous control, IAC kits, and electric fans.

Both systems feature a 3.5-inch handheld LCD touchscreen, an easy-to-use calibration wizard, complete tuning and gauge-display functionality, and Holley EFI’s industry-leading software suite that allows full laptop access for advanced users. Both work seamlessly with virtually all Holley EFI accessories, including shift lights, digital dashes, and even analog-style gauges, and both use Bosch LSU 4.9 wideband to relay air/fuel-ratio information to the ECU for accurate reading and precise tuning control.
