92205 Ultimate Sync Dual Quad EFI-systemen – Standalone

Standalone | Small Block Chevy | No Intake Included

The Ultimate Sync Dual Quad Standalone EFI System is designed for builders who already have a dual quad intake or are running a custom manifold setup and want the control, drivability, and performance of FiTech’s Ultimate Sync EFI without purchasing an intake they do not need. Developed by FiTech Fuel Injection, this system delivers classic dual quad appearance with modern fully sequential electronic fuel injection.

Each system includes dual Classic style throttle bodies, an external ECU with full timing control, main wiring harness, and dual wideband oxygen sensors. FiTech’s self learning technology continuously adjusts fueling in real time to deliver smooth idle, crisp throttle response, and consistent performance across a wide range of driving conditions.

This standalone configuration is ideal for performance street, strip, and custom builds. It is boost and nitrous compatible, supports E85 fuel, and is available with or without electronic transmission control for late model GM automatic transmissions. A Dual Sync Hall Effect distributor is required for proper operation.

Intake manifold not included.

Every Ultimate Sync EFI system is backed by FiTech’s industry leading 3 Year Limited Warranty.
