GDI Driver

The GDI Driver is a high-performance aftermarket controller designed to manage modern gasoline direct-injection systems. Capable of driving 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 fast injector response and precise control.
  • Pump Valve Management: Supports dual high-pressure pump valves at 12 V.
  • SENT Sensor Support: Handles up to 4 SENT sensors.
  • CAN Bus Connectivity: Provides diagnostic data for real-time monitoring and data logging.

Although designed to be compatible with ECUs featuring a GDI strategy, the GDI Driver is specifically optimized for use with EMU PRO. When paired, this combination leverages advanced algorithms and hardware to deliver unmatched precision in fuel delivery.

To simplify setup, we provide base maps for commonly used engines, including the VAG EA888 Gen 3 and Ford 1.5L Dragon GTDI Engine. The maps are designed for both the EMU PRO and the GDI Driver, ensuring seamless integration and efficient tuning. Additional base maps will be added in future updates.
