Massive Boost spiking - Eo1 HELP!

[Blade]

Hey guys

installed an e-01 last night...

The settings were taken off a the previous owners 34 gt-t

i drove it all last night and this morning and boost was holding at 0.88 bar to 0.96 max which is 13PSI

I take it for a spin tonight for a cruise...and i do the proper warm up etc....and drop her into 2nd put the foot down...everythings fine till 5000rpm not paying attention at psi reading and POP POP POP car starts jerking and i have to pull over....

Ever since then theirs no control on the boost...by 4000rpm im at 12 psi at 7000rpm (ive only gone their twice...too scared now) its reached around 20PSI

Ive tried turning the boost controller off...no luck...tried altering settings no luck...

I obvoulsy have to take it to a workshop and get it properly tuned....but would have tonights spiking to 23 about 4 or 5 times ****ed my car in anyway?

Ive got FMIC and GCG highflow...

Wat could the possible problems be? Settings from previous owner (34gt-t) not right for my car?

BUt it was working all last night and this morning holding at 0.88 bar...now after 4000rpm it just hits 22 psi

check all the hoses and make sure one hasnt come off

cheers

As Meggala said, go back over everything that you did and check all the air and electrical connections. If you can't find anything wrong, then put it back exactly the way it was before you installed the e-01.

So its definately not a setting problem?

I even turned the boost controller "OFF" and it still spiked to 20 every single time

Does the spiking to 20 wreck my car in anyway?

Im going outside to check the hoses now...cheers

[Blade]

Checked all the hoses and everything...no holes nothing...

I didnt installl the e-01...so im not sure what im looking at...

I see 2 hoses connected to the greddy valve...one going to the intercooler...one going to a gold round thing...both those hoses are in tact..

IN between those 2 hoses...i found a smaller hose...which aint connected to anything...i tried to follow where the start of it is...but lost it under the fmic piping...

I then followed the electrical wiring...its all in tact aswell

Could it be the wrong settings or something? it seemed basic...like i tapped in

Gain 10

Start Psi 2.7

Limiter - Constant

Set Psi - 7.7

id thought it hold at 7.7 instead it goes to 20+ and their no holes or nothing in the rubber pipes

My guess is the pipework to wastegate actuator has blown/fallen/dropped off. I suggest you take it back to whoever fitted the boost controller and have them fix it. In the interim don't drive it on boost.

If you want to have one more go yourself, then you need to find the wastegate actuator. It's on the turbo, has a rod comming out of one side and a hose out the other. Follow that hose until you find where was blown/dropped/fell off from and reconnect it.

Hope that helps

thanks heaps for your help sydney kid and meggala

How much would it cost...a rough ball park figure for to fix "wastegate actuator has blown/fallen/dropped off" for all those 3 problems?...

[Blade]

is the wastegate actuator a gold thingy? near this sort of round water holder with a black cap?

i have 2 hoses coming of my boost valve...one leading to fmic and one leading to a goldy thing? is the goldy thing the wastegate actuator?

If so.,..the hose from the boost valve to the gold thingy...is in tact mate

[Blade]

Such a MINOR problem

Thanks to Dr Drift - Sam who fixed the problem in an instant...

The valve had spun around...not securely fixed so it moved and bent the hose around...too me it looked the right way but it wasnt...so the hose was bent

[cameron]

is the goldy thing the wastegate actuator?

Correct

It controls your boost pressure, when the wastegate is closed boost will rise and then once set pressure is reached the wastegate will open to stop boost increasing.
