The Elite NEO Solution: 2500 ECU & Harness Kit for R34/Stagea

Unlock the full potential of the RB25DET NEO engine with the Elite 2500 + Nissan Skyline R34 GT-T & Stagea WC34 Plug ‘n’ Play Adaptor Harness Kit. This comprehensive package combines Haltech’s top-tier Elite 2500 ECU with a bespoke adaptor harness, creating a seamless path to advanced engine management. Designed for the R34 GT-T and Series 2 WC34 Stagea, this kit replaces the factory ECU, offering precise control over the NEO’s solid-lifter head, variable cam timing, and turbo system.

Engineering for the RB25DET NEO

The RB25DET NEO is a unique platform requiring specific control strategies. The Elite 2500 ECU is perfectly suited to manage the NEO’s requirements, including the VCT solenoid and the ATTESA AWD TPS signal (for Stagea applications). The included adaptor harness bridges the factory wiring directly to the Elite ECU, retaining critical dashboard functions like the tachometer and check engine light. The kit includes an external air temperature sensor, allowing for a reliable conversion to Speed Density tuning, which removes the intake restriction of the factory MAF sensor.

Operational Benefits

Installing this kit transforms the vehicle’s capabilities. You gain access to 4D tuning maps, closed-loop boost control, and robust engine protection features. The Elite 2500 supports flex-fuel integration, allowing you to run E85 for massive power gains safely. The system also supports the factory fuel pump voltage control module, ensuring the pump operates quietly at idle and provides full flow under load.
