Apexi - AVC-R
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).
