The new Profec is compact, powerful and easy to use. The large OLED Display, with the simple two-button / rotary-dial control, makes for intuitive operation. An ultra slim controll er can display in digital, bar-graph, or graphical modes and can be rotated 180 degree for installation with the included adjustable mount or flush mount.By separating the display and control unit in the driver’s compartment, from the engine compartment-mounted, waterproof, sensor unit, it makes installation straightforward. Only one thin harness is required to be routed through the firewall. The combination of the new 300kPa (43.5psi) integrated pressure sensor, the more compact solenoid valve and faster ECU processor, provide quicker response and the most stable boost curves yet. The Profec also maintains popular features like, Lo, Hi, Scramble boost presets, last-boost display, peak-hold recall, warning alert and safety limiter. Boost controller plumbing instructions for VQs: Port 1 goes into the intake manifold, Port 2 goes to the bottom of the wastegate (if using two wastegates, tee both gates together). Show more
