Fuel cut???, Does a 3SGTE need this? Options

[str8thugginit4ya]

Hello fellow 6GC'ers,

I tried searching for the answer to this, but I guess I either am the first person to ask this or I just suck at research. I have a 94 GT with a 3rd gen 3SGTE swap in it. I currently have my boost turned down to about 8lbs. Before I get into the problems I have, I just wanted to know if the 3S needs a fuel cut or not? Also, if it does, is it the 4 wire or 5 wire one? Please let me know as soon as you can. Ok, the reason why I have my boost turned down is because when I have the boost set to stock (14lbs), I get a sputtering, as if the car is struggling to pull whenever the boost hits a little less than 1 bar or higher. Please let me know if this could be because of not having a fuel cut installed or if it could be something else. I already put in new cap, rotor, plugs, wires because I thought it was my ignition system. Any input will be greatly appreciated. Oh, and I also have a AFC Neo hooked up to the car as well if that changes anything.


-Thanks, Ryan

if its strugglin for power then there might be a boost leak, are you using the factory top mount IC or a front mount?

Oh, ok. So I won't need a fuel cut right now, cause I'm only running 14lbs when the sputtering starts Neon90424. I'm using a sperco front mount intercooler. The piping was used before, so you may be right on the boost leak. I was already in the process of upgrading the charge piping anyways. But would that cause it to struggle for power only when it reaches about .75 bar. Before, I noticed it would struggle only around 5k, then I saw when it builds to about .75 bar is when it is struggling as well. So I don't exactly know if it's struggling when it hits .75 bar, or when it hits 5k. I'm daily driving it on .5 bar & if I punch it on .5 bar there's no problems.

Fuel cut is somethin that just happens, its not something you try to get, its a saftey thing for the motor. did you eliminate your stock boost controller? because you will hit fuel cut if the stock boost controller is still connected there for your aftermarket boost controller wont work.

when i first got my swap up and running i hit fuel cut at about 4k at 80mph, and you will kno when it hits fuel but because it falls flat on hits face out of no where, its like boooooooossttttt then pow! you got hit in the face with a shovel.. lol after that happened i eliminated my stock boost controller and then no more fuel cut. so if your not having those issues then you might have a boost leak, recheck all your clamps and couplers to make sure they are tight and not loose, if your using aluminum piping dont over tighten them bc they will bend.
