Holley Terminator X Engine Management Systems for GM LS Now Available at Summit Racing

There are plenty of ways to set up an engine management system for an LS engine. Some are expensive or designed for all-out race applications. Some involve jury-rigging OEM components (and crossed fingers).

The Holley Terminator X Engine Management System combines tunability with easy installation and proven components—and for a very affordable price. It comes loaded with base maps for common LS engine combinations to get you up and running quickly. The system self-learns as you drive, and features real-time fuel map learning that takes the guesswork out of tuning your base fuel table. And when you’re ready to get serious about tuning, the Terminator X system’s free, easy-to-use software suite allows full laptop access.
