The Haltech Nexus Skyline Plug-In ECU is a powerful plug-and-play engine management solution designed specifically for Nissan Skyline models.

With its "OEM Plus" auxiliary connector, the Nexus adds advanced capabilities like O2 control, Flex Fuel compatibility, oil and fuel pressure monitoring, and Drive-by-Wire throttle support, all without compromising factory integration.

For performance and motorsport enthusiasts, the Nexus ECU unlocks a suite of race-ready features including CO2 boost control, launch control, advanced torque management, nitrous control, race timing, and 128MB of onboard data logging. Setup is simple using the Haltech NSP software or Haltech Connect App, with Wi-Fi connectivity for real-time diagnostics and tuning.
