Model B4A Controller

$360.00   ($385 for vehicles requiring adapter plugs)

For vehicles with a single vacuum control valve.  Some vehicles require adapter plugs and price for those vehicles includes the adapter plugs.

Three-way exhaust controller suitable for installation in harsh environments such as the engine bay of a high-performance sports car.

Depending on application, the controller offers up to three modes of operation:

  1. Normal Mode:  The vehicle's ECU 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.
  3. Always Closed Mode:  Forces the valves to remain closed at all times.

On some vehicles, three-way operation is not available.  In these cases the controller is a two-way controller with Normal and Always Open modes.

Description

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 modification are required because the kit includes connector cables for the vacuum solenoids.  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.  Unplug the existing connectors to the vacuum solenoid valves, connect the included Y-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.
