Question about this product?

We're happy to help.

Discover the next evolution in engine tuning with our advanced Direct Injection (DI) control module. The DI Driver-4 is a highly configurable, cost effective and integrated solution, designed to give you full control of most modern solenoid type direct injectors and high-pressure fuel pumps.

Each DI Driver-4 module can allow up to four high voltage peak and hold solenoid Direct Injectors and one high pressure peak and hold Fuel Pump to flow up to their maximum amount of fuel at a very high engine RPM.

When combined with a G5 Voodoo Pro ECU, up to three DI Driver-4 modules can be connected together to control up to 12 Direct Injectors and two independent High Pressure Fuel Pumps. Together the G5 Voodoo Pro ECU and DI Driver-4 modules can control both Direct Injection and staged Port Injection on a single tune, giving you the ultimate all-in-one solution to achieve greater power and efficiency.

Connecting to your ECU and other DI Driver-4 modules is easy thanks to CAN Bus compatibility. Set-up has been simplified with our easy-to-use free DI Link software, which is highly user configurable over USB.

Housed in a durable, sealed CNC enclosure with a waterproof Superseal automotive connector, it’s engineered to withstand demanding conditions.

All this is backed by the industry-leading reliability and support you’ve come to expect from LinkECU.

The time has now come to unleash your Direct Injection engine with Link’s DI Driver-4, the easiest, most effective and most affordable way to tune DI on the market.

    I was struggling to get my ATOMX properly tuned and reached out to Link support. They walked me through every step over email and even gave me extra tips for my setup.

    Spent days hunting for a special boost control module for my turbo setup. Link had exactly what I needed, plus detailed specs!

    Installed the Link ECU and the car feels way more responsive. Had a small sensor setup issue at first, but once fixed it’s been solid and performs exactly as expected
