I have an '87 turbo without catylitic converters, a PFC F-Con, and a GCC. I keep getting boost cut under ANY amount of boost when both the stock pressure sensor and the pressure sensor that came with the F-Con are pluged in. If I unplug the stock sensor then it doesn't cut until around 9 psi. I bought the F-Con used with no instructions so I don't know whether to keep the stock sensor on or not. Not like it really matters cause it cuts out either way!

 

You need the fuel cut defencer still, along with both pressure sensors plugged in.

 

I had a (super cheap) fuel cut defensor that quit working. I switched to the F-con because It's supposedly has one built into it. I should get another one?

 

its not built in... it usually comes with one thats wired into the harness.

if you dont see the black box with FCD on it then you dont have one.

im guessing it IS the right one for your year make and model? sure hope so.

 

Ineresting. Is there a specific fcd for the F-con? I'm sure there is. Yes, I have the correct one, which for some reason it was a bitch to find for the early 2nd gen, but I got it.

 

i didnt have much luck with the hks fcd that came with my fcon back in the day.
just run any fcd for your series tii. plug it into the stock pressure sensor like normal. have a good one.
