Info

The FiTech 70004 Ultimate LS EFI kit is the ultimate LS ECU for DIY enthusiasts who want full control over their engine and transmission. Avoid having to buy additional software programs, learning how to think in computer code, or relying on a questionable 3rd party tuner. FiTech puts the engine and transmission EFI management back in your hands. The included color touch screen handheld controller allows for custom tuning adjustments to your LS engine as well as a self-learning program to get you on the road.

Leave the factory LS computer, wiring harness and intake in the junkyard where they belong. The FiTech Ultimate LS combo is a perfect match for 5.3 LS and 6.0 LS truck motors with tall and not so elegant factory intakes. The low profile fabricated sheet metal intake features short runners for a tricked out engine bay as compared to factory plastic engine covers. FiTech technology is custom cam friendly and is suitable for use with most 4.8 LS, 5.3 LS, LS1/LS6, and 6.0 LS engines with cathedral port cylinder heads producing up to 750 HP.

Kit includes:

  • Fabricated LS sheetmetal intake manifold
  • 102mm billet LS throttle body
  • Fuel rail with 55 lb/hr fuel injectors
  • Handheld controller with data logging capability and windshield mount
  • Fully programmable self-learning LS ECU
  • LS wiring harness 
  • Wideband O2 sensors

FiTech 70002 also includes a feature to control GM electronically controlled automatic transmissions. This allows you to configure shift points, shift firmness, when to downshift, among other features. Compatible GM transmissions include the 4L60E, 4L65E, 4L80E, and 4L85E. Other LS engine-only ECUs are avaialble in the FiTech Ultimate LS Series if you're using a different transmission.
