The GDI Driver is an aftermarket controller for modern gasoline direct-injection systems. It supports up to 8 peak-and-hold injectors and up to 2 high-pressure fuel pump valves, making it suitable for advanced multi-channel fuel system control.

Designed to work with ECUs using a GDI strategy, it is specifically optimized for use with EMU PRO. When paired with EMU PRO, it adds direct injector and high-pressure pump control along with diagnostic communication over CAN bus.

Key Features

• Converts 12 V to up to 70 V for fast peak-and-hold injector operation
• Supports 2 high-pressure pump valves at 12 V
• Handles up to 4 SENT sensors
• Provides CAN bus communication for configuration, diagnostics, and data logging
