Direct Plug-In - No Wiring Modifications:

The Link G4X NS13 is a true plug-in ECU, meaning it connects directly to your factory wiring harness using the 76 pin blue connector. No cutting, splicing, or modifying the factory wiring is required. Simply remove the factory ECU, plug in the Link ECU, and you're ready to tune. This makes installation straightforward and completely reversible if needed.

76 Pin Blue Connector - Verify Before Purchase:

IMPORTANT: This ECU is designed specifically for engines using the 76 pin blue ECU connector. Before purchasing, verify that your ECU connector matches the header shown in the product photos. Different model years and engine variants use different connectors, so verification is critical to ensure compatibility.

Onboard 4 Bar or 7 Bar MAP Sensor:

The ECU includes an onboard MAP (Manifold Absolute Pressure) sensor that can be configured for either 4 bar or 7 bar operation. The 4 bar sensor is suitable for stock to moderate boost levels (up to approximately 30 PSI), while the 7 bar sensor supports higher boost applications (up to approximately 85 PSI). This flexibility allows the ECU to grow with your build.

Manual Transmission Only:

IMPORTANT: This ECU is designed for manual transmission applications only. It does not support automatic transmission control. If you have an automatic transmission, this ECU will not work for your application.

Most Factory Features Supported:

The Link G4X NS13 supports most factory features including idle control, cooling fan control, and factory sensors. This means you can maintain factory-like drivability while gaining full control over fuel, ignition timing, and boost control. The ECU integrates seamlessly with your existing sensors and actuators.

Advanced Tuning Capabilities:

The Link G4X platform provides advanced tuning capabilities including:

• Full 3D fuel and ignition maps
• Boost control (electronic wastegate control)
• Launch control and anti-lag
• Traction control
• Flex fuel support (with additional sensor)
• Data logging and analysis
• Real-time tuning adjustments

I/O Expansion Options:

The ECU supports I/O expansion for additional features and sensors. This allows you to add capabilities like additional analog inputs, digital inputs/outputs, and advanced features as your build progresses. Check the Link website for available expansion modules and compatibility.
