Automotive Computers Are Our Passion!

Nemesis Engine Management Systems was born out of a passion to offer a user tunable computer without the constraints of the existing powerplant or the factory computer's limitations.

We want your tuning experience your build to go smoothly so we offer not only plug and play solutions for the most popular tuner platforms but we also provide tuned base maps for the most popular modifications and even boosted applications.  Companies like Flyin Miata, KO Racing, and Element Tuning have your Mazda, Subaru, Toyota, and LS V8 based engines covered with excellent maps and technical support.

The Nemesis software is a standout in a world of cumbersome, poorly laid out, and hard to tune ecus. With a real-time tuning interface redesigned for ease, logic, simplicity, and adjustability, it's easy and fast to find what you need to adjust and then make that change in an instant.
