The AVC-R is a digital boost controller that
allows the user to modify the boost pressure level on turbocharged
vehicles. While there are many boost controllers on the market, none of
the other includes as many features as the AVC-R, period. Despite all
of the complex features included the unit, the AVC-R is flexible enough
to be used by beginners. Entry level users need only to input a desired
boost level and the AVC-R's trademark self learning CPU processor does
the rest.
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.
