The Turbosmart BOV Controller Kit is a kit comprising a controller, solenoid & all cables and hoses required for installation. The BOV Controller itself is an electrical device that takes input from your throttle pedal & uses this to energise a solenoid and vent your chosen valve. The Controller is adjustable for sensitivity and activation duration allowing you to customise it to your needs. The BOV Controller is designed to provide engines such as diesel and other ‘low/no’ vacuum signal engines where a dump or Diverter Valves is required.
