HKS VPC (Vein Pressure Converter)
I mounted this under the dash next to the console. The VPC is connected to a socket that plugs in between
the ECU plug in from the fire wall and the ECU unit itself. Aside from the cramped quarters, the connection was
a snap. The left knob controls the fuel response on the initial throttle opening. I leave this one alone. The next
knob affects the overall fuel / air mixture. In my car, when this was set too rich, the fuel cutoff problem was present,
but by slowly leaning the mixture, I reached a point where the fuel cutoff stopped. The 3rd knob controls the
fuel / air mixture at idle. The 4th knob is used to control an optional "Graphic Control Computer" I don't have.
