?s about hks pf-fcon

[turbofanatic]

ok when i bought the car it already had a fuel control unit in it. it
says pf-fcon on one of the two controlers, the one with four nobs,
but i've been looking for this same controller at hks's website and
have had no luck. but if any of you have one or know of what i am
talking about i was wanting to know what each of the four knobs
actually does. one of them is gain, idle, o.p. out, and the other is response. and on the other controller it is just air/fuel controller that
can be raised or lowered by every 1500 rpm's. like i said every
where i have looked does not say anything about these controllers
with the pf-fcon system. and if anyone knows as to what each of the four
knobs does could u please explain. thanks

ok my mistake, i went and looked at the controllers and one of them
is the vpc and the other is the gcc. but i would still like it if someone
could tell me what exactly each nob does (response, gain, idle, o.p. out)
on the vpc. and one other ? i was trying to look for the pfc-fcons black box, in my car, that most of the places on the web show and was not
able to find it in there. is it possible to use the vpc and gcc together without the pfc-fcon?
