Tt Actuator & Fuel Cut?


Recommended Posts

As you know i fitted my TT air filter relocator kit and i started hitting fuel cut.

I suspected it was to do with the standard actuator being shit.

So i changed the actuator, put on the boost gauge, and fitted my FPR whilst i was there.

Winded the actuator all the way out and when booting it in 1st and 2nd it still hit fuel cut.

Winded the actuator out even more and it takes ages to hit full boost but when it does it going up to just over 0.9bar and hits fuel cut again.

Now, ive winded it out more, and it doesnt hit fuel cut, but.... the engine management light comes on and it takes an AGE to get to full boost.

Any sugestions?

p.s. - Im getting my SPS mani soon as well and when this is put on will it make it even worse???

any help appreciated.

Ricky.

taken from your other thread

if you fit your bcc your not going to hit fuel cut. however you will start over boosting and start melting things if your still on the stock mani. . if you just want to run under fuel cut don't bother fitting the bcc and reg. just fit the adjustable actuator. set it a bit longer than standard... and then see if its helped. its trial and error tbh. if your still having problems after that (good chance you will) either port the Wastegate or fit a restrictor ring in the exhaust and then raise the boost up to .85bar with an EBC. .hope that helps

about it being laggy, its because youve set the actuator arm so long, the wastegate flap isnt closing, shorten it, so the flap closes.

so only an actuator should sort the fuel cut?

nope, its fuel cutting cause of boost creep, either wind the boost down so it doesnt creep over fuel cut, or port your wastegate

For a rough guess i measured the arm length against the original actuator for a rough estimate, that was too much, so i winded it down about 10 spins in total, not it doesnt hit full boost till about 5000rpm and then still boosts to near 1bar.

So it still creeps obviously, so is porting the waste gate the only option? and WILL this stop the creep?

Also, im getting an SPS very very soon and getting it fitted, will this help the creep or make it worse?

no, ive already said theres a good chance it wont sort it, (which it hasnt)

if you read my post earlier you would of seen that i said, you can fit a restrictor ring in the exhaust instead.
