FiTech Ultimate LS EFI Kit, with MSD Coils/ACCEL Spark Plug Wires

FiTech Ultimate LS EFI System

The FiTech 70001 Ultimate LS EFI kit is 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. 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 500 HP.

FiTech Ultimate EFI System includes:

• Fabricated LS sheetmetal intake manifold
• 92mm billet LS throttle body
• Fuel rail with 36 lb/hr fuel injectors
• Handheld controller with data logging capability and windshield mount
• Fully programmable self-learning LS ECU
