FCD? Pointless, or Beneficial???!!
ok, i dont know a whole lot about fcd's. but i can get a good deal on one, (40$) i have an 89 turbo swap, full 2.5" turbo back straight pipe, cone filter, no emmisions, no PS and i run Pre-mix. Would a fcd help me for anything? or would it be beneficial to me to buy it? thanks guys

Yeah I have a 2.5 DP, Midpipe and racingbeat catback and I reach fuel cut easy....If your getting fuel cut then thats what the FCD is for.
If you dont want it I need one ill buy it for 40$!!!LOL

well its less a question of beneficial or pointless. it a question of needed or not needed. If you want to hit more than about 8 psi(with you mods and a cold day ill bet you hit it) without a stand alone engine management then you NEED it. IF you want to keep your car mostly stock and dont mind hitting fuel cut everyone once in a while then dont worry about it. You wont see any gains from an fcd it will just keep you from hitting fuel cut so if your not hitting fuel cut yet then your fine but if your modding your car and plan to add anything else besides what you have you will need it.

fuel cut is there for a reason.
I wouldn't add an FCD until I added a better (rewired) fuel pump, bigger injectors, S-AFC, and some dyno time. Then I'd tune with an MBC on my ported wastegate turbo to ~12PSI and make sure that the a/f's are really rich.. If you're not hitting fuel cut then why bother installing it, it can ONLY give you trouble.

you overboost more than what 1 or 2 lbs? i forget...from factory boost levels, and your engine cuts fuel, which can cause nasty things like detonation when it hits.

isn't the fcd just a resistor that goes between the boost sensor and ecu? why dont we just buy some individual resistors(radioshack?) and put the resistors in that wire? it'd be much, much cheaper.
