Fuel Cut :s

[GT Phayer]

i was havin a lil race with my mate the other day and wen i got to hi revs in 3rd gear it was asif the car stoped :S

all it has is a decat and an air filter is it normal to be hitin fuel cut ( if thats what it is )with those mods ?

People say "all cars are different" so yes it could be possible to get fuel cut with those mods. (Do you have an exhaust system aswell? I'm guessing you have?)

[GT Phayer]

yer just a rear box

Yes its possible to hit with just those mods, get a decent boost gauge to keep an eye on the boost levels, you don't want to be hitting the fuel cut to often as it can do damage.

my old 4efte engine used to hit fuel cut all the time and all i had was filter and dumpvalve

then after replacing the engine with a newer younger one i put a full system on it including decat, FMIC etc loads of mods and I've never had fuel cut since

so yes everycar is different but id get a boost gauge to check the boost levels

have you got a standard actuator or adjustable? if adjustable check the previous owner hasnt turned the boost up past fuel cut restrictions as well

[GT Phayer]

na standard actuator mate

[GT Phayer]

o and it has a fuel cut defender aswell

[WallaceGlanza]

You shouldn't be hitting fuel cut if it has an fcd, but you shouldn't have/need an fcd with just those mods anyway, you may actually be running lean.

As I said get a decent boost gauge so you can see what boost it's running.

ok mate i didnt put it on the bloke i bought it off did

[GT Phayer]

he said something about a cosworth turbo but its def a ct9 thats on there duno if the interals are diff and duno how i wud find out lol

[GT Phayer]

wouldnt if its runin lean affect the emissions ?

its just been m.o.t by myself and it sailed through

[GT Phayer]

this happens on lo boost by the way

[ste91]

Previous owner sounds like a bullshitter to me...

[Glanza_cl]

this happens on lo boost by the way

so it doesn't happen on high boost?

have you not got a boost gauge yet? if not stop posting go get one wire it in then see what your boosting... otherwise we cant really help much more other then say your over boosting.

[GT Phayer]

yer i just gota go for a drive and see sorry

i havent had it on high boost so il put it on and see what its ready sorry again

[Steve GT]

if that doesn't work uprate your fuel pump and see if that fuels it better

your standard fuel pump could be fooked and now fuelling it properly

eny engine management light before it its fuel cut?

[ep82 gtt]

i used to hit fuel cut flully standard, i tie wrapped all my actuator,vac lines and oem boost controller lines so so they was tight so there wasnt no air leaks and ported my wastegate and didnt have a problem.

now fitted ss mani,decat,2.5" cat back and relocated filter to the front and still on standard actuator and holds boost absoloutely fine.

[Steve GT]

yeh thats a good point too

just trial and error thing try everything suggested mate and see if it sorts itself out

[GT Phayer]

no management light up it doesnt do it anymore :S

it only done it the once its really weird lol

thanks for all the help guys

[Glanza_cl]

perhaps it was a miss fire, when was the car last serviced?

i would give it a good oil change, new plugs, new oil filter. fuel filter and i bet it will run like a dream

[GT Phayer]

will do mate thanks
