Model B4-FP Controller

$535.00

The Model B4-FP controller is a 2-way exhaust controller that is designed for installation in extreme environments as one would encounter in the engine bay of high performance sports cars.

The B4-FP is specifically designed for use in motor cars such as the Ferrari 488 Pista, F8 Tributo

and the Lamborghini Aventador SVJ and other motor cars with very sensitive vacuum control technologies.  The installation kit includes two additional vacuum control valves so that the electrical circuit for the controller is completely segregated from the circuit controlling the existing vacuum control valves.  This design allows control of the exhaust bypass valves without any error conditions or trouble codes.  And you can choose the Normal or Always Open mode at vehicle start.

The controller provides two modes of operation:

  1. Normal Mode:  The vehicle controls operation of the exhaust bypass valves.  This is the stock mode.
  2. Always Open Mode:  Forces the valves to remain open at all times, overriding the vehicle's ECU.

Description

Plug-and-Play  ... 100% Reversible

The kit is completely plug-and-play.  Power for the controller comes from the vehicle's fuse box.  A fuse tap is included to obtain power so no wiring modifications are required.  Since no modification are required to install, if you ever want to remove the controller the installation is 100% reversible.

Start-up option user configurable for Always Open or Normal Mode (ECU Control).

Simplified installation is straight forward.  The small size makes it easy to find a suitable location to install 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.
