Info

No dyno, no tuner, no factory re-flashed ECU! The FiTech 70050 Ultimate LS Standalone EFI ECU kit is the ultimate LS swap computer for DIY enthusiasts who want full control over their engine management. Avoid having to buy additional software programs, learning how to think in computer code, or relying on a questionable 3rd party tuner. The included color touch screen interface allows for custom tuning adjustments to your LS engine as well as a self-learning program to get you on the road. FiTech Ultimate LS EFI is the perfect product for using the factory GM intake, throttle body, and injectors, while leaving the factory GM computer and harness in the junkyard where they belong. FiTech technology is custom cam friendly and is suitable for use with most 4.8 LS, 5.3 LS, LS1/LS6, 6.0 LS, 6.2 LS, and LS7 GM engines.

Kit includes LS engine wiring harness, standalone LS ECU, one wideband O2 sensor and a handheld tuner. The FiTech 70050 is an engine-only ECU, however other FiTech Ultimate LS EFI ECU kits are available to control both engines and electronic transmissions.

Installation Instructions (PDF)

Application

  • Small Block V8 Gen III/IV LS-based Chevrolet street and performance engines.  Contains a 3 BAR MAP sensor for power ader applications that suppors up to 30 PSI of boost.

Notes

  • Kit comes with one 02 sensor.  If you'd like to run a second, you may want to source a Bosch 17014 from your local auto parts store.
  • This kit does not work with drive by wire throttle bodies and variable valve timing.  These engines can be modified to remove these components.
