FiTech Ultimate LS Drive-By-Wire Engine Management Systems

The FiTech Ultimate LS Drive-By-Wire (DBW) Engine Management Systems provide seamless LS engine swaps, offering modern electronic throttle control, improved drivability, and superior throttle precision over cable systems. These FiTech systems are idea for LS engine swappers looking to bypass the complexity of mechanical linage and cable management, as well as for builders looking for modern OE-style throttle performance with customizable drive models or for high-performance or custom applications demanding precise, electronic throttle tuning.

Key benefits and features:

* Superior Throttle Control—eliminates throttle cables and reduces the "twitchy" low-speed behavior, providing a smoother, more responsive, and customizable pedal feel
* Simplified installation—eliminates the need to fabricate throttle cables or brackets
* High-Flow Performance—available with 92mm or 102mm throttle bodies designed to support high-performance, boosted, or high-horsepower LS builds
* The ECU automatically learns the engine's requirements after inputs like engine size and cam type are entered into the touchscreen, optimizing fuel and spark control
* Built-in Drive Modes—includes pre-programmed drive modes that adjust throttle feel for daily driving, towing, or performance
* Optional Transmission Control—some kits feature built-in controls for GM transmissions like the 4L60, 4L65, 4L80, or 4L85
* Engine protection and reliability—features comprehensive engine protection features (such as 3-Bar MAP sensors) that, in the event of a sensor failure, can default to safe operation rather than shutting down
