A'PEXi AVC-R Electronic Boost Controller | (420-X905)
The AVC-R also uses a highly durable, fast action solenoid valve to physically control the boost . The valve movement (Boost Duty Cycle) can also be modified. Raising the duty cycle increases boost response, while lowering the duty cycle will slow boost response. This feature allows boost response adjustment for varying turbo sizes. Since larger turbos take longer to spool up ( bad low end response) the duty cycle should be raised under lower RPM's for better response. The opposite should be done for smaller turbo's ( excellent low - mid range response, but limited top end power.) A'PEXi engineers address this issue by including extra menus for RPM based boost control. Drag racers may want to utilize the Gear based boost control function. Aside from the basic functions above, the AVC-R has a Start Duty Setting (allows the boost to momentarily overshoot according to gear).
The AVC-R also includes a Scramble Boost function which allows the user to momentarily raise or lower the boost level at the push of a button. Raising the boost level is commonly used when an extra burst of power is needed (ex. entering a freeway). This feature can also be used in drag racing. The driver can set the main boost level to a low setting for maximum traction then, once full traction is achieved, the scramble boost can allow the vehicle to boost full power.
The AVC-R displays data in three different modes: Numerical, Analog, and Graph. Numerical Mode allows the user to monitor up to four different parameters in numbers and also shows peak hold values on demand. The Analog Mode displays up to two values in an easy to read meter style display. Peak Hold is also included in this function. The Graph Mode offers real time graph plotting with a Ghost map trace feature built in. The graph can replay movement up to 60 seconds.
