Run Low-Impedance Injectors Safely With Your Link ECU

Running low-impedance fuel injectors with grouped injection? The correct ballast resistance is critical to controlling injector current and protecting your ECU's injector drivers.

The Link ECU Ballast Resistor – 1Ω 50W x2 provides a simple, reliable solution for applications using low-impedance injectors that require additional resistance.

Designed for motorsport and performance EFI installations, this assembly combines two high-power 1-ohm, 50-watt resistors in a durable mounting bracket for a clean, professional installation.

Designed for Low-Impedance Injectors

Low-impedance injectors can draw significantly more current than high-impedance injectors. When the ECU and injection strategy require ballast resistance, running the injectors without the proper resistors can place excessive electrical load on the injector drivers.

This ballast resistor assembly helps properly limit that current when using compatible low-impedance grouped injection configurations.

Features

• Genuine Link ECU ballast resistor solution
• 2 x 1Ω resistors
• 50W rating per resistor
• Designed for low-impedance fuel injectors
• Suitable for compatible grouped injection configurations
• High-power aluminum resistor housings
• Integrated heat-dissipating design
• Heavy-duty metal mounting bracket
• Compact installation
• Ideal for performance and motorsport EFI applications

Built to Handle Heat

Ballast resistors convert electrical energy into heat during operation.

That's why this assembly uses finned aluminum resistor housings capable of dissipating heat while providing the durability needed in demanding automotive environments.

For best results, the resistor assembly should be securely mounted in an appropriate location with adequate airflow and away from components that could be damaged by heat.

Perfect for Custom EFI Builds

This ballast resistor assembly is an excellent addition when wiring a compatible Link ECU to older or performance-oriented low-impedance injectors.

Common applications can include:

• Turbocharged engines
• High-flow low-impedance injectors
• Custom engine swaps
• Race cars
• Drag racing applications
• Grouped/batch-fire injection setups
• Custom Link ECU wiring harnesses

What's Included

• 2 x 1Ω 50W ballast resistors
• Metal mounting bracket

Important Compatibility Note

This product is specifically intended for applications requiring ballast resistance with low-impedance injectors and grouped injection.

Injector impedance, ECU injector-driver capabilities, wiring configuration, and injection mode should be verified before installation.

Not every Link ECU installation requires ballast resistors. High-impedance injectors and ECUs with appropriate peak-and-hold injector control may use a different configuration.

Build Your Link ECU System the Right Way

A properly wired fuel-injection system is just as important as the calibration controlling it.

If your combination requires ballast resistors, the Link ECU 1Ω 50W x2 Ballast Resistor Assembly gives you a clean, durable solution for integrating low-impedance injectors into your EFI system.
