Is My Actuator Set To High- Sheite Help!

[nazzurro19]

i think my actuator is set too high but im not sure basically :

if i full throttle in 2nd after about 4k revs it starts to choke cough n splutter

if i dont full throttle in 2nd but hold the boost gause to 0.8 and let the revs build up its fine

basically im on the rolling road 2moz and i know they are guna full throttle and not balance the accelerator and let the revs build up

so is my actuator ok or have i got it set to high - if i set it to 0.7 can i full throttle through the rev range and then not experience this choking spluttering sort of thing??

or have i got it all completely wrong ? and can nobody on here full throttle without it choking?

sounds to me that you are hitting fuel cut. have you git a fcd?

[nazzurro19]

Nope not fitted but like i say if i half put my foot down balance my gauge at 0.8 i can let the revs build uo but i need to be able to full throttle so do i need to reset my actuator?

fuel cut will kick in at 0.75 bar so if your boosting above that then its deffo fuel cut. turn your actuator down cause hitting fuel cut a lot aint doing your engine any good lol

[nazzurro19]

I never hit it cause i never full throttle lol how do i turn it down buddy?

Have you got an adjustable actuator then?

[Steve GT]

take the arm off the actuator and turn the nut down 2 or 3 turns re-connect then take it for a spin. then keep repating until you get a safe bosst under fuel cut (0.75 bar)

[joe-ep91]

if so you need to:

1) unclip the actuator from the wastegate undoing the cir-clip

2) find the nut on the actuator arm and loosen

3) Wind the actuator arm inwards turning it clockwise, only a few turns

4) tighten up the nut and re-connect to wastegate connector

hope this helps

lol, beat me to it

[nazzurro19]

Yeah i got a hks adjustable one ill go try it soon so basically get it to 0.7 and then i can full throttle n not get boost cut ?

[joe-ep91]

yep thats it mate, you can actually take it to about 0.8bar which is just under fuel cut, but it depends whether you are suffering from slight boost creep which might exceed 0.8bar in higher revs on full throttle

Yeah its set 0.8 now n i get it so ill just lower it taa guys now i need a mate with some tools

[nazzurro19]

I took off the circlip un done the bolt took the arm off the wastegate twisted it 2 times to make it longer pushed the wastegate over a tiny bit so it would now clip back on to the arm of tge actuator and did the bolt back up but now there is a really tiny noise when ever i let off the throttle ??! Have i done something wrong? Should i have shortened the arm to turn down boost!! ? Argh please help

[ollie ryan]

i adjusted mine down from 1bar yesterday to 0.7 and everytime i let of the throttle there is a slight tiny noise

[nazzurro19]

Is it the shorter the arm the less bar u run? Cause i just made the arm longer and now my boost aint as powerful but im still getting a petty cut?!

Can some one give me a really in depth guide as im currently sitting in the middle of nowhere stuck and i dont no wat to do! :'(

thats a pdf file of how to set one up properly dude should help.

from looking at that file the shorter the actuator the more boost it runs

[nazzurro19]

ive now put it bk tohow it was as every other setting made a funny tinnie noise and was slow on boosting up , so ill just have to not full throttle and just hope it dont blow up

[enots]

cant you just ask them to set it up before they do a run??

[nazzurro19]

If i get it set to 0.7 does that mean i can full throttle and never hit fuel cut ? Or when i full throttle will i still get boost creep and fuel cut?

[enots]

can't remember what fuel cut is think its 0.8 so yeahh it its set to 0.7 u should be able to full throttle it as long as you dont get any boost creep

[nazzurro19]

I got it rolling roaded today it turns out its not boost creep or the fuel cut its misfiring at around 0.6 5750 revs!
