"The HKS VPC is a fuel management device that is designed to physically
and electronically replace the OEM air metering devices for improved
air flow and precise fuel delivery control. OEM air metering devices,
such as Air Flow Meters (Flapper/Plunger types) and Air Mass Sensors
(Hot wire / Karmen Vortex types) measure the amount of air flowing
into the intake manifold in order to properly control fuel enrichment
levels. Aside from offering no adjustment or reprogramming options to
take advantage of dramatically higher amounts of airflow or larger
fuel injectors, the OEM air meter also represents a significant
restriction to the intake system. To overcome this restriction, the
VPC physically removes the OEM air meter to dramatically improve
airflow capacity and converts the system to what is referred to as a
speed density system. By utilizing a 16-bit central processing unit,
the VPC reads it’s own intake air temperature sensor and absolute
pressure transducer (B-MAP sensor) signals and then converts those
signals to one that is recognizable by the factory ECU. The VPC also
incorporates the ability to upgrade the internal application specific
ROM program to correctly compensate and take full advantage of larger,
Higher flowing, HKS fuel injectors and/or the greater air flow
characteristics of larger turbos. Each application specific ROM
program is calibrated for a specific injector size, fuel pumps,
camshafts, and/or turbos, ensuring that the correct injector pulse
width is calculated to prevent driveability and reliability problems.
Since the VPC “piggy-backs” the factory ECU, all factory systems are
still intact and operational. Fine tuning of fuel curves can be
further achieved by integrating the plug-in GCC or by wiring in a
Super AFR."
