Ultimate LS Standalone ECU w/o Trans Control

The Ultimate LS Standalone ECU without transmission control from FiTECH FUEL INJECTION is designed specifically for LS engine swaps and performance builds. This unit is ideal for builders who want independent fuel and ignition management without factory transmission interference, making it suitable for dedicated drag cars, classic muscle car restorations, or standalone LS platforms with manual or non-OEM transmission control.

This ECU simplifies the integration of an aftermarket fuel injection and ignition system by eliminating the complexity of factory harnesses. Its standalone architecture allows for control over fuel delivery, ignition timing, and engine parameters through a user-friendly tuning interface. The compact design, measuring 12.25 x 8.75 x 12.25 inches and weighing 8.58 lbs, fits easily in tight spaces while the rugged housing ensures reliability under extreme conditions.

Builders looking for a reliable and flexible engine management solution will benefit from the Ultimate LS Standalone ECU. It integrates seamlessly with LS platform sensors and ignition systems, providing real-time control over critical engine parameters. While it supports closed-loop lambda feedback and cold-start enrichment, users should note that additional components may be required for boost control in forced induction applications.
