Hooked up AVC-R, Having overboost issues? Pics of installation! Help!

[underground]

Hey guys,

I hooked up the AVC-R this afternoon, and I'm having major problems with overboosting...

It's as if the boost solenoid doesn't do anything but let the turbos boost to the sky...

I set the settings on the AVC-R to 1.0 bar and 40% duty cycle so that I could begin fine tuning it...

The boost goes all the way to 1.5 bar when I get on it... These are on stock turbos! So, I took it back home and have been trying to figure out what I did wrong...

It's only pulling -220 mg hg , according to the AVC-R when idle, which I think is not enough vacuum.. Sorry, trying to do conversion as I'm from the states and don't know what this means..

Also, do I need to plug up the NC side on the boost solenoid?

Here are some pics, hopefully you can follow my installation and let me know what I did wrong...

Thanks!

Did u plug in the apexi supplied sender unit for the avc-r to read boost pressure?

And if so did you put the little air filter in the line cause this can play havic with the readings?

I'm not sure if the air filter was installed or not.. I will have to go back and check..

Apexi Supplied Sender Unit?

The only parts included are the screen/controller, solenoid valve, pressure sensor..and clamps, hoses, etc..

part # 3 and #13

pressure sender and air filter...

Yea, pressure sensor is installed, but the air filter is not...

I didn't realize it was that vital...

But, i still don't believe the problem has anything to do with the air filter...

Here's some more pics...I know I jacked up this install, something is not hooked up properly. I think it probably has to do with how I connected all the components with the hoses..

Give me a few minutes to get the pics uploaded and posted...

Check the highest duty cycle that it is hitting, I bet you it is going to 99% trying to get the boost up before the wastegate is even open. Turn feeback off and just play with your duty cycles...

The thing is a frickin pain in the ass.

I think the AVC-R is hooked up correctly...

My worry is that the boost gauge is not...

According to the directions the apexi pressure sensor is supposed to be hooked up with a T-fitting to the factory boost pressure sensor..

Thing is I don't have the factory boost pressure sensor as it didn't come with my motor..

But, the shop that did the swap did hook up the Autometer Electric boost gauge..

and this is what I hooked the Apexi pressure sensor hose with a T-fitting to..

I don't understand where the Automer gauge gets its reading from.. There is only one line going into it with a T-fitting on the other end... The T-fitting goes to the fuel pressure regulator and the Apexi racing BOV.....

I cant really make much sense with the photos, i kinda need to be there

but i had some problems holding boost when i first got it,

I cleaned up all my vacuum hoses IE took out all plastic joiners and used as little amount of T pieces as i could (i even disconnected my boost guage), and shortened all the hoses as much as possible

now it holds it almost perfect, the most it over/underboosts is 0.01bar

Hi, check my above post... I changed it...
