FiTech Ultimate LS Standalone Drive-By-Wire EFI Engine Management System
Modern electronic throttle control and self-tuning engine management for GM Gen III/IV LS engines without integrated transmission control.
Product Overview
The FiTech 70050DBWSA Ultimate LS Standalone EFI System gives custom engine builders and motorsport enthusiasts total flexibility when upgrading GM Gen III and Gen IV LS engines to electronic Drive-By-Wire (DBW) throttle control. Designed specifically for builds that do not require integrated transmission control—such as manual transmission swaps or setups utilizing a standalone transmission controller—this system eliminates mechanical throttle cables, linkages, and tedious bracket adjustments.
Engineered with OEM-quality components and FiTech’s proven self-learning calibration strategies, the 70050DBWSA features selectable drive modes to tailor pedal feel and throttle response for daily driving, towing, or high-performance track use. Because it is supplied as a standalone engine controller package, you retain complete freedom to pair it with your preferred DBW throttle body, pedal assembly, and intake manifold configuration.
