EVCU-1 Pressure Monitoring Valve Control Unit

The EVCU-1 is the intelligent control system engineered to move beyond simple RPM- or speed-based valve activation. It operates by dynamically monitoring and reacting to exhaust backpressure—the critical factor that truly dictates engine performance. This system allows you to precisely dial in the ideal backpressure thresholds, ensuring your exhaust valves open exactly when needed to guarantee maximum power output across the entire rev range while simultaneously canceling out performance-robbing backpressure and drone.

Control is put directly into your hands with the included remote key fob, providing instant manual override capabilities. More than just a simple on/off switch, the EVCU-1’s advanced programming is smart enough to recognize aggressive driving behavior. If you accelerate hard, the unit detects the rapid pressure change and immediately opens the valves for an instantaneous, full-volume acoustic experience. Conversely, during normal or cruise driving, the valves operate conservatively, maintaining a quiet, refined tone until commanded otherwise.

Engineered to integrate seamlessly with both CAPRISTO and OEM valved exhaust systems, the EVCU-1 allows you to bypass restrictive factory valve settings, providing a true "always open" mode for maximum sound and performance when desired. For the enthusiast who requires precision, personalization, and uncompromising performance, the EVCU-1 is the necessary core technology for mastering your vehicle's voice.
