GReddy Profec Electronic Boost Controller

GReddy Profec Electronic Boost Controller

Easy to use controls

Simple rotary-dial and dual push-button layout was designed and developed with an emphasis on simple operation (for Profec programing basics, pease see our blog:)

 Dimensions (89mm X 36.5mm)

Intuitive Dial Operation
Unique to this latest generation PRofec is a larger ergonomic rotary-dial control.  Along with a new compace display unit size, the controller can be easily mounted within reach of the operator.  This all together creates an intuitive boost controlling experience.


New Compact Solenoid and Improved CPU Control

The PRofec uses a new more compact 3-port boost solenoid, controlled by a faster CPU.  The result is a quicker responding system, that provides our most stable boost curves yet.

Excellent Visibility with the OLED Display

OLED (Organic Light-Emitting Diode) display offers excellent visibility at a wider range of angles.  It is also much brighter then standard LCD screens, allowing the display to be more compact, yet still effective.

Slim Design Offers Multipole Mounting Options  (89mm X 36.5mm - 11mm thick flat-screen)

Surface mounting, as well as, the rotating of the display by 180 degrees, opens up numerous mounting options.  An adjustable mounting bracket is also included.

Display/Control Unit, Sensor Unit with Pressure Sensor, Boost Solenoid, and Adjustable Mounting Bracket

Separating the Display Unit from the Sensor Unit

To keep the Display Unit as slim as possible, a separate water-resistant Sensor Unit was developed. The added benefit of this however, is the convenience of installation. Now that the Sensor Unit is mounted in the engine room, only a single thin harness is required to be routed through the vehicle's fire-wall.


Select between 3 Types of Boost Display Screens
(kPa or PSI)

 Numerical Display

 Bar Graph Display

 Map Trace Display


* Programable LO and HI Boost Pre-Sets, with a 3rd Scramble Setting

Timed Over-Take Boost Level

* Intergrated 300kPa (43.5psi) high-performance boost pressure sensor (within the Sensor Unit)

* The PRofec can display the last (peak) boost value after each boost session

* The Peak-Hold Function can display the maximum boost recorded

* Boost levels and stability can be fine-tuned by adjusting the GAIN and START BOOST settings

 Warning Feature displays an visual and audio alert when the unit detects an over-boost situation

If the boost warning level is surpassed, the PRofec can reduce boost levels via a programable Limiter Function
