Syvecs S7i Plug & Play ECU Kit Nissan Skyline GTR R32/33/34

Syvecs S7i Plug & Play ECU Kit | Nissan Skyline GTR (R32 / R33 / R34)

The Syvecs S7i Nissan Skyline GTR Plug & Play ECU Kit is the ultimate engine management solution for the legendary RB26DETT. Designed to modernize the electronics of the R32, R33, and R34 GTR, this kit replaces the aging factory Denso/JECS ECU with a high-speed, triple-processor system. The S7i provides the perfect balance of motorsport-grade features and cost-effectiveness for owners who demand world-class control without the excessive I/O count of the S7Plus.

Built with a dedicated FPGA, the S7i manages high-RPM engine position tracking with microsecond accuracy. This is critical for the RB26, ensuring rock-solid ignition and injection timing even at 9000+ RPM.

Elite RB26 & ATTESA-ETS Integration

The Skyline GTR is defined by its sophisticated all-wheel-drive system; the S7i is engineered to work in harmony with it:

• ATTESA-ETS Compatibility: Full communication with the factory 4WD controller ensures that your torque-split logic remains fully functional and optimized for maximum traction.

• HICAS Integration: Maintains seamless operation with the factory rear-steering systems (where applicable) through shared CAN bus data.

• Direct Fit PnP: Plugs directly into the OEM wiring loom. The S7i is housed in a direct-fit enclosure, making installation clean and reversible.

• Individual Cylinder Knock Control: Sophisticated closed-loop knock detection for each cylinder, allowing you to push the RB26 safely to its absolute limit.

Performance & Safety Features

• 12-Position Map Switching: Toggle through engine calibrations (boost levels, traction strategies, or fuel types) on the fly using a dash-mounted switch or factory buttons.

• Rolling Anti-Lag: Build instantaneous boost while cruising—essential for eliminating lag on big single-turbo conversions during roll racing.

• Flex Fuel Integration: Automatic, real-time mapping adjustments based on Ethanol content (E85). The ECU automatically scales timing, fueling, and boost targets based on fuel quality.

• Proprietary Traction Control: Advanced motorsport logic utilizing individual wheel speed data for superior grip management that far outperforms the early-90s factory systems.

Technical Specifications

The Ultimate Safety Net

Protect your RB26 with Syvecs' industry-leading Safety Trip logic. The S7i monitors critical parameters like fuel pressure, oil pressure, and individual cylinder knock in real-time. If a sensor value exceeds safe limits—such as a drop in fuel pressure during a high-boost pull—the ECU instantly triggers a safety strategy (fuel cut or boost reduction) to prevent catastrophic engine failure.
