Simply Advanced Boost Control.

ARK Design's ultra-compact Advanced Boost Controller (ABC) is praised in Japan for its ease of use. The ABC accurately dials in boost pressure with its simple and intuitive controls. ARK Design engineers selected the key functions tuners look for in a boost controller, and packed them into the ABC's compact design. The ABC offers two independent boost settings, over-boost warning, peak-hold, and a simple to use patented "see-saw" control switch.

The built-in overboost warning function offers a visual notification if the the user defined boost warning level is reached. The over-boost warning light has 8 different colors that can be selected. For additional safety, the ABC also monitors the rate at which boost pressure increases. If the ABC senses boost rising at an abnormal rate, the pressure is dropped to the base level of the wastegate.

The ABC utilizes an advanced electronic solenoid to accurately control boost pressure at two user-preset levels. With two independent boost settings, users have the option of changing their vehicle's boost level by the simple touch of a button.

A patented "see-saw" control switch with dual direction switching and a clickable roller-button combo make setting the ABC and accessing its functions easy.
