Life Racing GDI Driver 12V | High-Voltage Direct Injection Interface

The Life Racing GDI Driver is a high-performance external expansion module designed to drive gasoline or diesel direct solenoid injectors. By bridging the gap between a host ECU and high-pressure injectors, this unit provides the precise high-voltage current control necessary for modern direct injection strategies. Built to professional motorsport standards, it ensures your fuelling system remains reliable under the most demanding racing conditions.

Precision Injector Control

Designed to integrate seamlessly with a host engine control unit, the GDI Driver provides:

• 4 Direct Injector Drivers: Capable of driving high-pressure solenoid injectors with surgical precision.

• Internal High Voltage Generation: Automatically generates the high-voltage "boost" phase required to open GDI injectors rapidly against high fuel pressure.

• Adjustable Drive Power: Software-configurable output settings allow you to tailor the drive profile to your specific injector requirements, optimizing performance and heat management.

Seamless Integration

• Input Mapping: Accepts 4 injection pulses from the host ECU to trigger the high-voltage firing sequences.

• Versatile Power Supply: Operates on a wide 6V to 32V input range with full reverse polarity protection.

• Compact Footprint: Measuring just 140 x 80 x 36 mm, it is easy to mount in tight engine bays or electronics trays.

Autosport-Grade Construction

True to the Life Racing heritage, the GDI Driver is engineered for the harshest environments:

• Chassis: CNC machined, "O" ring sealed, and anodised aluminium case for superior thermal dissipation and durability.

• Connector: Features a premium Deutsch Autosport connector for secure, vibration-resistant wiring.

• Environmental Sealing: Rated to IP67, providing complete protection against dust and water immersion.

• Temperature Resilience: Fully operational in extreme conditions ranging from -25°C to +85°C.

Primary Applications

• Driving Gasoline Direct Injection (GDI) solenoid injectors.

• Driving Diesel Direct Injection solenoid injectors.

• Expanding the capabilities of a host ECU for high-pressure fuel systems.
