The FiTech Ultimate LS EFI kits are the ultimate LS ECU for DIY enthusiasts who want full control over their engine. 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. FiTech Ultimate LS combos are a perfect match for LS and Vortec truck motors with not so elegant factory intakes. The available low profile fabricated sheet metal intakes features short runners for a tricked out engine bay as compared to factory plastic engine covers. Plus, FiTech technology is custom cam friendly.

 

Some FiTech Ultimate LS kits 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.
