Forza Audi R8 Electronic Valve Controller Kit - FC-AUD-B4A

The Forza Componenti exhaust valve controller kit is the complete solution that allows the user to take full manual control of the vehicle's vacuum-actuated exhaust bypass valves. The controller has a circuit board that controls the negative side of the exhaust valve vacuum solenoids. The user can manually open the exhaust bypass valves to have that classic engine sound at all speeds and engine RPMs. Of course, you can return the operation of the exhaust valves factory whenever you wish. This kit provides three different operational modes: Normal Mode: In this mode, valves operate the same as stock. Always Open:  Selecting this mode will force the exhaust valves open — and remain open. Always Closed:  Selecting the Always Closed mode will force the exhaust bypass valves to remain closed at all times. This mode is especially useful to ensure that your vehicle is as quiet as possible.  Note: This feature was added at the request of people who track their cars at locations with strict noise standards and did not want the vehicle ECU to open the valves at high engine RPM. Each kit is assembled using components designed to withstand the rigors of installation in the engine bay of a modern sports car. The enclosure is extruded aluminum. The internal circuit board will withstand the elevated temperatures that tend to exist in the engine bay of a vehicle. The connection cables are constructed using high serviceability TPE insulated cabling rated to 105° C. Connectors are weatherproof automotive connectors to resist moisture. Plug-and-Play  ... 100% Reversible The kit is completely plug-and-play. Power for the controller comes from the existing connector to the car's exhaust bypass vacuum solenoids, and no wiring modifications are required because the kit includes connector cables for the vacuum solenoids. Installation is straightforward. You only need to select a location to install the controller, unplug the vacuum solenoids, connect the included cables, and route the cables to the controller. Once installation is complete, you use one button on your remote transmitter to open the exhaust bypass valves and the other button to close the valves and return control to the car ... and, you also have the ability to configure a manual on/off switch that you can mount inside your vehicle. Since no modifications are required to install, if you ever want to remove the controller the installation is 100% reversible. The controller includes one Remote Control Transmitter. Additional transmitters are available. FITMENT: Audi R8 Audi RS4 FEATURES: Completely self-contained controller box User configuration to use either the remote control key fob or a manual on/off switch Approved FCC, CE, and all international governing bodies Always Closed option can be used to keep the valves closed at all times All internal components are integrated into the Printed Circuit Board for higher reliability Fail-safe mode ... when vehicle ignition is turned off, exhaust bypass valve control reverts to factory ECU No Check Engine Lights (CEL) or Diagnostic Test Codes (DTC) Cables assembled using water and oil-resistant flexible cord - 18 AWG stranded Class K copper conductors per ASTM B-174. The cable is rated SJEEOW for severe outdoor service with TPE insulation rated to 105° C. Type SJEOOW cords are ideal for flex applications in harsh high-temperature environments where the highest degree of water and oil resistance and extended service life are essential. All electrical cables use weatherproof connectors High-gain external antenna for improved remote control performance Kit includes full installation instructions and one remote control transmitter, mounting accessories including cable ties and high temperature tolerant adhesive mounts Remote control can be programmed to newer versions of HomeLink (version 5 and higher) that are integrated into many cars. Older versions of HomeLink (earlier than 2013) will not support the 433MHz frequency of the remote transmitter The controller kit is warranted to be free of defects. If the controller should fail within 12 months of installation, return it to us for repair or replacement
