Ecumaster GDI Controller

The GDI Driver is a high-performance aftermarket controller designed to manage modern gasoline direct injection systems. Capable of controlling up to 8 peak-and-hold injectors and 2 high-pressure fuel pumps, this module delivers precision and reliability for advanced engine setups.

Key Features:

Injector Control: Converts 12 V to up to 70 V for rapid injector response and precise control.

Pump Valve Management: Supports dual 12 V high-pressure pump valves.

SENT Sensor Compatibility: Supports up to 4 SENT sensors.

CAN Bus Connectivity: Provides diagnostic data for real-time monitoring and data logging.

While designed for compatibility with GDI strategy ECUs, the GDI Driver is specifically optimized for use with EMU PRO. When combined, this pairing leverages advanced algorithms and hardware to deliver unparalleled precision in fuel delivery. To simplify setup, we provide base maps for commonly used engines, including the VAG EA888 Gen 3 and the Ford 1.5L Dragon GTDI engine. The maps are designed for both the EMU PRO and GDI Driver, ensuring seamless integration and efficient tuning. Additional base maps will be added in future updates.
