Syvecs S8 Engine Control Unit

Professional Engine Management | Motorsport Performance | Advanced Engine Control

The Syvecs S8 is a high-performance Engine Control Unit designed to deliver exceptional precision, flexibility and reliability in demanding motorsport and performance vehicle applications.

Developed using the proven Syvecs engine management architecture, the S8 combines powerful processing capabilities with extensive input/output functionality, advanced engine control strategies and comprehensive calibration options.

Syvecs engine management technology is trusted by professional racing teams, OEM vehicle manufacturers, specialist engineering companies and aftermarket tuning workshops around the world.

At the heart of the S8 is a twin-processor architecture combining a high-speed RISC processor for real-time code execution with a dedicated FPGA for accurate engine position tracking and scheduling of critical engine control events.

This architecture allows engine control scheduling to operate independently of incoming engine position signal patterns, improving processing efficiency, flexibility and timing accuracy during demanding transient conditions.

With 24 general-purpose analogue inputs, 28 high/low-side driver outputs, eight ignition drivers and dual CAN Bus communication, the S8 provides extensive flexibility for sophisticated engine management installations.

The S8 is housed in a compact sealed billet aluminium enclosure with a single 88-pin waterproof connector, providing a practical solution for professional motorsport and custom vehicle installations.

Combined with high-speed Ethernet communication and onboard data logging of up to 64MB, the S8 provides a powerful platform for professional engine calibration, monitoring and performance development.

Advanced Engine Management

The S8 provides precise control over fuel delivery, ignition timing and engine operation, supported by a powerful processing architecture designed for demanding motorsport applications.
