The new Ultra Port LS system from FiTech takes a fresh approach to LS engine management. Instead of cobbling together different components, they’ve created an integrated package that simplifies the entire EFI conversion process while delivering precise control over your engine’s performance.

FiTech includes everything needed to get this installed on your LS.

What sets the Ultra Port LS apart is its thoughtful engineering and completeness. Rather than piecing together components from different manufacturers, FiTech delivers an all-in-one package that takes the guesswork out of fuel injection. Each system includes a precisely matched intake manifold, fuel rails, injectors, ECU, sensors, and a complete wiring harness.

The heart of the system is FiTech’s advanced Retro Port LS ECU, which handles both engine and transmission control. This standalone unit brings modern engine management capabilities while remaining remarkably user-friendly. An included handheld touchscreen controller with a magnetic mount puts tuning capabilities right at your fingertips.

Aesthetics weren’t an afterthought either. The Ultra Port LS comes in two striking finishes: a sleek black for a murdered-out look or a brilliant polished finish that makes a statement in any engine bay. The universal 4150-style throttle body flange ensures broad compatibility with most intake manifolds.

FiTech offers the system in configurations for both LS1 and LS3 style intake manifolds, accommodating the most popular LS engine variants. The port injection design optimizes fuel delivery and throttle response, while self-learning software takes the complexity out of initial setup and tuning.

The Ultra Port LS system’s plug-and-play nature belies its sophisticated capabilities. While installation is straightforward, the system offers deep-tuning potential for those who want to fine-tune every aspect of their engine’s performance. The included handheld controller provides real-time monitoring and adjustment of critical parameters.

Adaptability Is Key

One particularly clever feature is the system’s adaptability to various timing control setups. Whether running a traditional distributor or a modern coil-near-plug ignition, the Ultra Port LS seamlessly integrates with your chosen configuration.

For LS engine builders seeking a complete, well-engineered fuel injection solution, FiTech’s Ultra Port LS system delivers sophisticated engine management in a refined package. The combination of broad compatibility, thoughtful design, and serious power-handling capability makes it a compelling choice for anyone looking to modernize their LS powerplant.

Just remember: while the Ultra Port LS provides everything needed for engine management, you’ll need to ensure your fuel system (pump, lines, and fittings) can support your power goals. After all, even the most sophisticated injection system needs a proper fuel supply to perform its best.
