what happens when you over boost and you don't have an fcd? I know it cuts fuel but how do you get it back? Thanks!

 

ps. what would be mounted in the front of my engine bay that is a black box that has two tubes going into it one saying in and the other saying out? it says hks on it.

 

Fuel is cut at 8.6psi. As soon as boost drops below this (i.e. you lift off the gas), fuel is turned back on.

That sounds like the solenoid for an electronic boost controller. One hose will go to the turbo, one to the wastegate.

 

ahhh thanks alot man I apriciate that I was woundering what that was. I'm yanking all this stuff out because it seems like all these wires that are not factory is the problem for my car not starting.

 

Uhh yeah... if you yank that hks system... and there's another doohickey in the cabin... that says "HKS EVC" on it, i'll give ya $20

 

lol, I know sorry man I feel like a moron I"m just not the one that put all these mods in this car. I do and will have a buch of stuff just with cut wires maybe I'll reuse them I don't know.

 

well look if you want to make some money, pm me, i might buy some of the stuff with cut wires off ya

 

well I might do that I got so far an electrotic boost guage, fuel pressure guage, turbo boost guage, air fuel ratio, although I don't know if that one works never saw it work, turbo timer exhuast temp guage. I think thats it all work just either getting rid of them maybe. Make me an offer or trade and we will talk.

 

oh yeah all these parts are hks

 

oh and I've got an s4 turbo with no shaft play and spins very freely just yanked because I have an upgraded turbo.
