level on turbocharged vehicles. While there are many boost controllers on the market,
none of the other includes as many features as the AVCR, period. Despite all of the
complex features included the unit, the AVCR is flexible enough to be used by beginners.
Entry level users need only to input a desired boost level and the AVCR's trademark self
learning CPU processor does the rest.
The AVCR 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 trubo's
( excellent low - mid range response, but limited top end power.) Apex 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 AVCR has a Start Duty Setting ( allows the boost to momentarily overshoot according
The AVCR 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.
