S5 Power FC
 

I picked up a PfC a few years back & also Bought the Banzairacing.com adapter Kit & modded FC igniter I'm really happy with the eMs & kit I got from Banzai. Since installing I've been left with some questions regarding what all the PFC controls, in regards to stock & my present setup .
1. In a stock S5 Turbo, the duty solenoid & switching Solenoid handle boost control etc.. What Does the PFC do? (Dumb I know)controlling them or overriding them ?
2.i have a T70 turbo external waste gate I'm obviously over stock boost levels does this make the Duty solenoid ,switching solenoid,prc solenoid etc useless or even redundant I read that I could be over boosting by leaving the duty solenoid plumbed in my setup has been plumbed & wired in like stock with the acceptation of ,air control valve,air pump ,a/c,p/s a,ir supply valve & air bypass valve are gone (still have BaC) should I delete it (Chris @ Banzai gave me an over simplified answer " I can get rid of it "
3. Should I just remove the spider & solenoids? & plumb the waste gate so it's relieving exhaust pressure by spring only Or is the pfc actually controlling boost through the stock components? Or only up to a certain point/ boost level ?
4.i have been searching & searching although there are a lot of threads & how to's on PFC /s5 fc wiring & " my car won't start " I have not seen anything in regards to how it's working WITH the engine as far as the afore mentioned devices
Car runs great I rebuilt the engine
Been digging for info for a long time there is a lot of info of course here on Rx7club ...I wonder if there exist a definitive Power Fc/FC S5 thread I've searched the single turbo thread ( 90% FD)

When you go bigger turbo a few lb's over factory boost, does the stock boost control system become irrelevant,redundant ( I probably asked this before)
Thanx to any heads that bother

The PFC can control the boost via the boost control solenoid or a MAC valve type solenoid. With the external wastegate you need to lower the duty cycle in the boost setting substantially. OR you can remove the factory solenoid and run off wastegate spring, the PFC does not care what you remove.

Send an over simplified question with absolutely no details and you will get an overly simplified answer ever single time.
