HKS GCC Graphical Control Computer
The Graphical Control Computer (GCC) is an additional electronic tuning component designed to add flexibility to the VPC and PFC F-CON. The GCC simply plugs into the HKS harness and allows the user to adjust the fuel pulse duration at specific rpm intervals and/or boost levels. At each of the five intervals, the GCC can richen or lean-out the programmed fuel curve. The GCC will interpolate or average between points of adjustment to ensure a smooth fuel delivery.
