Fuel cut?, seems like fuel cut, but have fcd Options

[6gsillyca]

The other day I was driving up a big looong hill, and decided it give er a bit. I was boosting around 10-11 that night, got up to about 5500-6000 rpm and then she TOTALLY bogged down. It felt like someone slammed on the brakes. This is the first time its done this. I have a hks fcd installed. is there any way to "test" it to see if it working properly?

I also noticed my EGT's were high (1400+) and as soon as I let up they started to drop back down.


Any input?

Fitting an FCD is suicide, pure & simple.

The fuel cut is there for a reason, the reason is it stops the car leaning out, want to know what leaning out is… you probably just did it!!

Your fuel leaned out, the intake temps went sky high, EGT’s go through the roof, loadsa knock, ecu retards timing & brings in the VSV you feel a sudden slam & car runs like a 3 legged dog.

So many owners have killed their engines over here because of the FCD’s… no one uses them anymore

what you said is only true for the 3rd gen 3sgte. he has a 2nd gen 3sgte that uses the afm to measure air. the map sensor on that motor is ONLY used for fuel cut and for the factory boost gauge. its totally safe to install an fcd on a 2nd gen motor.

The later part of what I said goes for all versions, I was talking about fuel starvation/leaning.
Granted an FCD on a GEN III is a complete no no, but the same goes for the other versions unless you have supporting mods, there was no mention of supporting mods when I posted.

Why I stand by FCD's being suicide is because on teh GEN II teh stock fuel maps only go to 12PSi, teh later ones including cs/rc are set to 17PSi, if you go above the set values teh injectors will be working at 100% duty (Fuel starvation/leaning, det, timing retarded, VSV kicks in blah, blah, blah) (How old are the injectors?? When was teh last time they were flow tested?? etc etc, all these elements add to teh soup so to speak)…
IIRC to determine if you have a 17PSi ECU it has a B in teh 2nd part of the part number.
If you have teh 17PSi version ECU you will then have to work out if the FCD is a raised limit version or teh version that just removes teh fuel cut all together… loose wire?? Limit set too low??
Reading about teh intercooker doesn’t sound healthy at all
