CES-3 Programmable Control Unit

The Capristo CES-3 Programmable Control Unit (Article No. 04AZ 007 03 003) is the world’s most advanced exhaust valve management system, specifically engineered for the discerning enthusiast who demands a perfect balance between a civil street presence and a raw motorsport soundtrack. As the ECE-Certified version, this unit is fully homologated for use in regions with strict noise and emissions regulations, ensuring your vehicle remains compliant without sacrificing performance.

Back Pressure Intelligence

The core of the CES-3 is its ability to "think" alongside your engine. By utilizing a dedicated pressure sensor, the unit monitors the exhaust back pressure in real-time.

• Engine Protection: The system is programmed to prioritize engine health. If it detects a spike in back pressure that could lead to heat soak or component fatigue, it automatically opens the valves to vent the gases, regardless of the current mode.

• Performance Mapping: Unlike factory systems that open valves based on static RPM or throttle position, the CES-3 opens based on actual engine load, ensuring optimal torque delivery and a seamless transition in the power band.

Programmable Operational Modes

The included remote control allows the driver to toggle through three distinct personalities:

1. Cruise Mode (ECE Compliant): Valves stay closed at lower speeds and RPMs to ensure a quiet, drone-free experience that meets city noise standards. They open automatically under high load to protect the engine.

2. Sport Mode: A dynamic middle ground where the valves open earlier in the rev range, providing a sportier acoustic profile for spirited driving.

3. Open Mode: The valves are forced 100% open, allowing the engine to breathe freely and deliver its maximum natural volume.

Technical Specifications & ECE Homologation
