Haltech Nexus Plug-in ECU for Nissan Skyline R32 / R33 / R34 GT-R
The Ultimate Engine Management Solution for the RB26DETT.
The Haltech Nexus Plug-in is a revolutionary leap in engine management for the Nissan Skyline GT-R. Moving beyond traditional "plug-and-play" units, the Nexus series combines an ECU, power distribution module, and data logger into a single, compact housing that fits directly into the factory ECU location. This unit is specifically engineered to handle the complexities of the R32, R33, and R34 chassis, providing seamless integration with factory systems like ATTESA and the R34 MFD.
- Wideband Controller Built In: Single Channel Onboard Wideband Control (sensor pack sold separately)
- Internal 4-Bar MAP Sensor: Supports up to 45 PSI of boost without external MAP wiring.
- Onboard Logging: 128MB of high-speed internal memory for professional-grade data analysis.
- Chassis Support: Full compatibility with R34 MFD and ATTESA 4WD systems.
- Part Number: HT-231801
⚠️ CRITICAL SKYLINE CALIBRATION & FITMENT DATA
Manual Transmission Only: This Nexus Plug-in is designed exclusively for manual transmission models. It does not support factory automatic transmission control or modern automatic conversions without secondary controllers.
MAF Elimination: This ECU is intended to run on a **Manifold Absolute Pressure (MAP)** strategy. The factory Air Flow Meters (MAFs) are no longer required. You must plumb a vacuum line from the engine's intake manifold to the ECU's onboard MAP sensor port.
Wideband Integration: While this unit has the hardware to support wideband control, the **Wideband Sensor and Harness** are sold separately unless you purchase the "Wideband Bundle" version of this kit.
Essential Expansion & Accessory Options:
• Nexus Skyline with Wideband Bundle (HT-231802) - Includes the LSU 4.9 sensor and harness.
• IO Expansion Harness (HT-189002) - Best for adding Flex Fuel and Pressure sensors to cable-throttle builds.
• DBW Expansion Harness (HT-189003) - Required for Drive-By-Wire electronic throttle conversions.
