Hks Gcc

[pdtaylor18]

Well i do have one of these and wondered if it could be plumbed into a standard ECU that has been chipped. My biggest problem is that I have no clue on what wires do what so to help I could do with someone that has one in any car as these are universal. You can get the looms to plug them into a HKS piggy back ECU but only from USA and they are silly money for what they are as you have to have the entire loom for ECU-Piggyback bit.
I would imagine that it must only be RPM, AFM in and out,power,earth maybe but just need someone to confirm what colour wires do what and is this possible. Its really no different to a Apexi SAFC and they plumb in without a specific loom.
The GCC is an electronic tuning component designed to add additional flexibility to the fuel tuning capabilities of the VPC, PFC F-CON or F-CON S. The GCC simply plugs into either the VPC or F-CON harness and allows the user to further adjust the air / fuel ratio at five specific rpm points. Each five points offer an adjustment range of 16% rich to 12% lean, in 2% increments, of the base value. Four different selectable rpm ranges allow maximum rpm level flexibility when tuning the fuel curve. The GCC will interpolate, or average between the rpm points of adjustment to ensure a smooth transition of fuel delivery throughout the RPM band.

Any info much appreciated

The gcc will only work with a pfc f-con or vpc, you cannot wire it straight to the ecu.
Think of the gcc as the equivilant to a commander for the apexi power fc. Tho these unit are fuel only and don\'t change the ignition timing.
