Description

The Syvecs S7D-8 ECU delivers an exceptionally high level of precise engine management control, designed specifically for modern Direct Injection (DI) engines used in high-performance road cars, motorsport and advanced OEM-style applications.

The ECU features a triple-processor architecture, combining a high-speed RISC processor for core code execution with a large FPGA dedicated to ultra-high-speed engine position tracking. This allows code scheduling to operate independently of signal patterns, significantly improving accuracy, flexibility, and efficiency, particularly under transient conditions such as rapid load and RPM changes.

This powerful hardware platform enables highly advanced control strategies while remaining intuitive and easy to calibrate using SCal software and S7 firmware. The Syvecs S7D-8 is also designed to support Plug-and-Play kits, offering extensive programmable CAN Bus, CAN FD support, and the ability to meet unique OEM and aftermarket hardware requirements.
