Description

FiTech 70050DBWSA Ultimate LS Standalone Drive-By-Wire EFI System (No Transmission Control)

Take absolute control of your engine swap with the FiTech 70050DBWSA Ultimate LS Standalone Drive-By-Wire (DBW) EFI System. Engineered specifically for GM Gen III and IV LS-powered applications, this standalone system is designed for builders who want modern electronic throttle control without being restricted by bundled components like intake manifolds, pre-selected throttle bodies, or transmission controllers.

By eliminating mechanical linkages, throttle cables, and cumbersome brackets, this DBW setup delivers smoother acceleration, sharper throttle response, enhanced reliability, and a significantly cleaner engine bay.

The system features FiTech’s proven calibration strategies and built-in preset drive modes, allowing you to fine-tune pedal feel and responsiveness for everything from daily driving and towing to heavy performance use or custom tuning. It gives you the complete flexibility to pair your ECU with your preferred compatible drive-by-wire throttle body and pedal assembly.

Key Features:

• Standalone Drive-By-Wire Control: Fully integrated electronic DBW controller eliminates mechanical throttle cables and linkage.

• Component Flexibility: Supplied without a throttle body, pedal, intake, or transmission control so you can tailor your hardware to your exact build goals.

• Customisable Drive Modes: Includes preset calibration modes to easily adjust throttle progression for daily driving, towing, or performance tuning.

• Self-Learning Technology: Streamlines custom LS engine swaps with self-learning ECU capability and precision fuel/spark management.
