Fuel cut defender

[burgess18]

Right I have a fuel cut defender installed on my starlet ep82 an I set it to number 8, but it still fuel cuts? but I have. Boost controller that isn't set up yet and a fuel pressure reg which is getting set up on 27th could this be a reason for it still hitting fuel cut anything over 0.75 it fuel cuts badly any ideas could the fuel cut defender be nackerd?

[Weyro]

is it an HKS fcd?

when i used one setting 8 moved fuel cut up to over 1.1bar, so either yours is faulty or not wired in right

[burgess18]

Yeah it's a hks one but wouldn't the fuelin an everything play a part? An my boost control or sard fuel reg isn't set up

[Weyro]

no the fuel pressure isnt relevant to when boost cut is activated, only the fcd affects that

its possible that your boost is spiking up to where boost cut has now been moved to

i should point out that you should have the fuel pressure set up first, then start raising the boost pressure

if the sard has a pressure gauge you can set the fuelling yourself

you should have the car running, remove the small vac pipe from the sard, then set the pressure to 3bar/44psi, then reattach the vac pipe

Right okay will try that then if not its the fcd must be nackerd as it came on the car an was tucked away on 12

[burgess18]

Also what could cause a boost spike?

[Weyro]

setting 12 is basically off, it has the least affect oh the MAP signal

are you running the standard ct9 turbo? if you have a decat, and cone filter, this can make the boost spike up really high, only way to really stop this is to restrict the air filter, by partially wrapping it with duct tape, or to port the wastegate inside the turbo

[burgess18]

Yeah I'm running standard ct9 with a ported mani, Decat an screamer pipe, uprated fuel reg, uprated fuel pump, Fmic, come filter relocation kit sits right at the front of the grill, fcd, boost controller, it's odd as soon as I go over 0.8 bar give it till about 4000 rpm then it's like your hitting a brick wall an it pops flames haha, it's all getting set up etc on 27th but I just wounderd maybe the fcd isn't working but when I turn the car on an turn the setting up or down the car shakes slightly so it must be doing something?

[Weyro]

yea its definitely doing something if its making the engine dip a bit when u turn the dial, but it could still be faulty.

what boost controller do you have?

try setting the fcd to 12, so its basically off, and try setting your boost controller to 0.8bar and get it to hold the boost steady

once you have done that, then put the fcd to setting 10, and boost to 0.9 bar and get it to hold steady

then finally setting 8, and 1bar boost

remember to set the fuel pressure first

if the car is hitting fuel cut even with the boost set at 0.8bar then its definitely a boost spike

[burgess18]

Right okay I will try that then thanks mate will message ya back later once I've had ago

[burgess18]

I have a hks evc mate

[Weyro]

which verison? if its this one, i can talk you through the setup

[burgess18]

When I adjust it with the vac pipe off its at 3 bar soon as vac pipe goes on it goes to 2.5 bar??

[burgess18]

No it's not that version mate it says hks evc black limited on it it's quite a big square screen an then it has a deprecate part with 2 knobs saying a and b

[burgess18]

Not having much luck today was adjusting the bar on the regulator then went to lock it off an the nut snapped off the reg great! Anyone got the top half of a sard regulator where the vaccum pipe goes?

[Weyro]

Yes that's right, the vac line lowers the pressure when at idle, and raises it when on boost. So as long as its 3bar with the vac pipe off that's fine.

That's probably one of the newer versions so I'm not really sure, but ill look into it

Aw thats crap, the nut doesn't need to be really tight.

[burgess18]

Right okay an Ahhh okay cheers an yeah I gathered that now no anyone with the part I need? I've gotta try an get the other bit of the nut out now haha gonna be fun may have to but the whole new unit

[Weyro]

Don't know anyone with that part, you could try posting in the wanted section or give eBay a shot
