GCC
(Graphic Control Computer)
The GCC is an additional electronic tuning
component designed to add flexibility to the VPC, PFC F-CON or F-CON V.
The GCC simply plugs into either the VPC or F-CON harness and allows the
user to adjust the air/fuel ratio at specific rpm levels. Think of
it as a graphic equalizer for the fuel system. Five points of adjustments
allow up to 16% rich or down to 12% lean. Four different rpm ranges
allow for maximum flexibility when tuning the vehicle. The GCC will
interpolate, or average between the points of adjustment to ensure a smooth
fuel delivery. The GCC also incorporates an LED, which changes color
indicating whether the fuel mixture is in fact being altered by the GCC.
When used with an F-CON, the GCC can be used to adjust the air/fuel ratio
under boost of rpm levels.
