Product Description:

• Product Definition: The Capristo E2E (Electronic-to-Electronic) Valve Control Kit is an auxiliary electronic module designed for the precise, manual command of electronically controlled exhaust valves specifically on BMW models. The kit typically includes the main control module and a dedicated wireless remote control unit.

• Vehicle Function: The module integrates into the OEM valve control circuit, effectively overriding the factory engine control unit (ECU). This enables the driver to manually command the exhaust valves open or closed regardless of the vehicle's engine speed, load, or selected driving mode.

• Installation and Fitment: The system features a simple plug-and-play installation process. It connects directly into the existing OEM wiring harness using specialized connectors and does not require cutting, splicing, or permanent modifications to the vehicle's factory wiring or engine management system.

• Core Benefits: The primary advantage is achieving instant, on-demand acoustic customization. The kit eliminates the ECU's pre-programmed sound restrictions, allowing the driver to fully control and maximize the exhaust system's volume and tone across the entire RPM range.

• Durability and Warranty: The module is constructed with robust electronic components suitable for high-performance automotive applications. It incorporates a safety feature that defaults the exhaust valves to the open position upon power interruption. The unit is designed to be maintenance-free and is typically covered by a Capristo manufacturer's limited warranty against defects.
