DI Driver-4
The Link ECU DI Driver-4 gives you proper standalone control of modern direct-injection engines, without relying on the factory ECU to operate the injectors or high-pressure fuel pump.
Designed as the perfect companion to Link’s G5 Voodoo ECU range, the DI Driver-4 handles the high-voltage, high-current control required by modern solenoid-style direct injectors while allowing the ECU to take care of the actual fueling strategy.
Each DI Driver-4 Controls:
- 4 Direct Injectors
- 1 High-Pressure Fuel Pump
- Solenoid-type direct injectors
- High-pressure fuel pump solenoids
- CAN communication with the ECU
- USB-C configuration through Link's free DI Link software
For larger engines, multiple DI Driver-4 modules can be used together. When paired with the G5 Voodoo Pro, Link supports configurations with up to 12 direct injectors and two independently controlled high-pressure fuel pumps.
The system can also be used alongside conventional port injection, allowing a single ECU package to control staged Direct + Port Injection.
Built for Serious DI Applications
Direct injectors cannot simply be connected to a conventional ECU injector output. They require very fast, accurately controlled high-voltage and high-current operation to open against the extreme fuel pressure found in a direct-injection system.
The DI Driver-4 handles this specialized injector drive requirement while giving the tuner control over the system through Link's dedicated DI Link software.
The module is highly configurable, allowing the injector and high-pressure pump control characteristics to be matched to the hardware being used.
Serious Injector Drive Capability:
- 17.9A Maximum Boost Current
- 65V Maximum Boost Voltage
- 17.9A Maximum Peak Current
- 2000µs Maximum Peak Duration
- 5.0A Maximum Hold Current
- 164ms Maximum Hold Duration
Does not support piezo direct injectors.
When operating Bosch HDEV 5.2 direct injectors, Link specifies operation up to 14,200 RPM, making this a genuinely motorsport-capable DI solution rather than simply an OEM replacement controller.
Perfect for Modern Engine Swaps & Standalone Builds. The DI Driver-4 opens up a ton of possibilities for running newer direct-injected engines on standalone management.
