Link ECU DI Driver-4 – Direct Injection & High Pressure Fuel Pump Driver

Link DI Driver-4 – Direct Injection & High Pressure Fuel Pump Driver

The Link DI Driver-4 is a configurable direct injection driver designed to control modern high-voltage peak and hold direct injectors and high-pressure fuel pumps.

When used with Link's G5 Voodoo range of ECUs, the DI Driver-4 provides the additional high-voltage control required for Direct Injection applications, while allowing both Direct Injection and staged Port Injection to be managed within the same ECU calibration.

Each DI Driver-4 can control up to 4 direct injectors and 1 high-pressure fuel pump.

Suitable Applications

Each DI Driver-4 supports:

• Up to 4 high-voltage peak and hold Direct Injectors

• 1 high-pressure peak and hold fuel pump

• Link G5 Voodoo ECU applications

• Direct Injection engine builds

• Staged Port + Direct Injection applications

Multiple DI Driver-4 modules can be used where additional injector channels are required.

When combined with the G5 Voodoo platform, multiple modules can support up to:

• 12 Direct Injectors

• 2 independent High Pressure Fuel Pumps

Inputs and Outputs

• 4 Direct Injection Injector Drives

• 1 High Pressure Fuel Pump Drive

Communications

• 1 CAN Bus

• Software-configurable CAN termination

• USB Type-C connection

• Configuration using Link DI Link software

The CAN connection allows the DI Driver-4 to communicate with the ECU and additional DI Driver modules where required.
