Syvecs S7D ECU

The Syvecs S7D ECU range delivers an exceptionally high level of engine management control, purpose-built for modern direct injection engines. Utilising a powerful triple-processor architecture, it combines a high-speed RISC processor for code execution with a large FPGA dedicated to ultra-precise engine position tracking. This allows control strategies to operate independently of signal patterns, resulting in greater accuracy, flexibility and efficiency, particularly under transient conditions.

Designed for high-performance road and motorsport applications, the S7D range supports advanced control strategies while remaining intuitive to calibrate using Syvecs SCal software.

Available in multiple configurations for 4, 6 and 8 cylinder applications, each variant shares the same core performance and functionality, with scalable I/O to suit the specific engine platform.

Key Features

• Full engine and torque-based control including fuel, ignition, VVT and drive-by-wire
• Advanced knock control, traction control and motorsport-grade calibration strategies
• Flexible boost control supporting solenoids, electronic wastegates and CO₂ systems
• Launch control, rolling launch and anti-lag strategies for performance applications
• Comprehensive engine protection including knock, lambda, EGT and configurable safety trips
• Integrated limp modes and fail-safe strategies
• High-speed onboard data logging with simultaneous live tuning via SCal
• Extensive CAN, CAN FD and communication support for seamless vehicle integration
• Expandable via Syvecs CAN-based modules for additional I/O and functionality
