The Ultimate S15 Upgrade: Nexus S3 & Harness Kit
Elevate your Nissan Silvia S15 or S14A to the cutting edge of motorsport technology with the Nexus S3 Plug ‘n’ Play Adapter Harness Kit. This package combines the flagship Haltech Nexus S3 VCU with a vehicle-specific adaptor harness, providing the most powerful and versatile engine management solution available for the SR20DET platform. Designed for the serious enthusiast, this kit offers uncompromised control and connectivity.
Engineering for Maximum Capability
The Nexus S3 VCU brings advanced features like built-in oscilloscope, 128MB data logging, and Wi-Fi connectivity to the S15. The included adaptor harness ensures seamless integration with the factory loom, routing signals for the SR20’s sensors and actuators. The S3 supports full sequential injection and ignition, variable cam timing, and advanced boost control strategies. The harness facilitates the addition of extra sensors via the auxiliary I/O port, allowing for comprehensive monitoring of engine vitals like oil pressure and fuel pressure.
Operational Benefits
With the Nexus S3, users can implement advanced traction control, launch control, and engine protection strategies. The system supports drive-by-wire conversions (requires additional hardware) and flex-fuel tuning. The plug ‘n’ play installation minimizes downtime and ensures a reliable electrical connection, allowing you to focus on tuning and driving. The S3’s capabilities far exceed the factory ECU, making it future-proof for any level of modification.
