If you’re considering utilizing a factory intake, injectors, and cable operated throttle body, FiTech’s Ultimate LS standalone self-learning ECUs will get your engine ready for optimal performance. This self-learning Ultimate LS ECU is the best solution for a standalone LS swap and replaces the OEM computer and harness. This kit is dedicated to LS or similar engines with crank and cam sensors. The Ultimate LS standalone kit will self-learn to most cam swaps. Usually only very large cam grinds will require additional tuning in the system. Easily tuned for even the most novice tuner, this kit includes a touch-screen controller for easy setup and configuration.
Application: LS or similar engines with crank and cam sensors.
Small Block V8 GEN. III/IV LS-based Chevrolet street and performance engines. Contains a 3 BAR MAP sensor for power adder applications that supports up to 30 PSI of boost.
Note: This kit does not work with drive by wire throttle bodies and variable valve timing. These engines can be modified to remove these components.
Not legal for use on pollution controlled vehicles: FiTech’s Ultimate LS System is not approved for use on emission controlled vehicles. This system is designed to control the EFI and ignition on LS based engines being retrofit into older vehicles that do not require emission controls.
