Syvecs S-GDI ECU | Integrated Direct Injection Control
The Syvecs S-GDI (also known as the SDI) is the industry-leading solution for enthusiasts and tuners seeking integrated Gasoline Direct Injection (GDI) management. Built upon the legendary S8 architecture, the S-GDI is a specialized powerhouse designed to directly drive high-pressure GDI injectors without the need for an external driver box. It offers the same elite-level processing and precision as the S8 but is streamlined with a focused I/O count for 4-cylinder GDI applications.
Housed in a sealed billet aluminium unit with an 88-pin waterproof connector, the S-GDI provides a compact yet uncompromising platform for modern DI engines from manufacturers like Ford (EcoBoost), GM (LT/Ecotec), and Bosch Motorsport.

Why the Syvecs S-GDI is the Premier Choice for DI Engines
-
Direct Injector Control: Unlike standard ECUs that require complex external modules, the S-GDI features integrated drivers capable of handling all major GDI injectors (Ford, GM, Bosch). This simplifies your wiring loom and improves system reliability.
-
FPGA Accuracy: Utilizing a dedicated FPGA for engine position tracking, the S-GDI ensures that high-pressure injection events are timed with microsecond precision, which is critical for maintaining engine safety and efficiency in direct injection platforms.
-
Flexible Staged Injection: The ECU supports both Direct Injection and Port Injection strategies (DI + PI), allowing for secondary port injectors to be added for high-horsepower builds where the factory DI system reaches its flow limit.
-
Advanced Safety & Logic: Includes dual knock inputs, high-speed data logging, and sophisticated Drive-By-Wire (DBW) control. It also features integrated high-pressure fuel pump (HDP) control for a complete DI solution.
-
Expandable Performance: While natively supporting 4-cylinder DI engines, this architecture can be scaled for higher cylinder counts using the Syvecs S12 and external GDI expansion boxes.
Perfect for Modern Performance Platforms
The S-GDI is the core of numerous high-performance Plug-and-Play (PnP) kits, providing total control for:
-
Ford: Focus ST/RS (EcoBoost) and Fiesta ST
-
VAG Group: VW/Audi TFSI and TSI platforms
-
Custom Builds: 4-cylinder DI swaps and motorsport GDI applications
