Default avc-r help requested.

I installed my AVC-R yesterday. I think i did things right but i can't really tell with this stupid manual and some of the postings that i've read.

I've done a ton of searching for "avc-r" and avc-r install. Most of the stuff that I have read is relating to the settings in the ebc after being installed. Nothing really on stuff about putting in the actual hardware..

Anyways, after getting it installed i am getting 1.35 kgf/cm2 peak boost. if i do the conversions that shows up to be about 19.2 psi
I used http://www.convert-me.com/en/convert/pressure to do the conversion. My EGTs are getting in the 925C+ range when running that high of boost too on the stock turbo and IC

Here are my questions:
1. should i run new plumbing with the tubes they give me or can i use the existing tubing that was pulled off the factory BC?
right now i am using the stock tubing after pulling it off the fbc.

2. how the hell do i lower the boost so it doesn't go 19.2?
I thought i had it in learn mode. I pretty much left everything the way it was except for changing the cylinder size and other items but pretty much everything else is as it was out of the box.

I thought 17PSI or so was about as high as this stocker can go.

Thanks in advance for your help. Please no posts saying "search" cause i have and i can't find the answers i need.

0) Do a search

1) definitely use all new plumbing. It's only a few bucks at the store, and you'll eliminate the problems associated with the restrictive OEM stuff.

2) proper settings will lower your boost (assuming the installation is correct). Those can definitely be found here somewhere. If you're really stuck, speak up.

The stock turbo will do upwards of 22psi, but works most efficiently/best around 16-17psi. Anything over that and it becomes increasingly less efficient.

925C? Umm, I think that's impossible, considering that the melting point of plain Al is 658C. You would've seized your engine had it gone that high.

Default ugh

925celsius = 1697 farenheit
Too high indeed. I'm not melting yet but...getting there.

so anyways, I should run the tubing right off the wastegate to the COM side of the apexi solenoid right? removing the T connector and all that other crap?
And do the same for the other tubing that was run to the other side of the fbc and hook it to the NO port?
i think i have my sides right. acrobat keeps crashing on me so i can't see the manual right now.

anyways, i will check this all out at home. I think i am going to turn avc-r to OFF while i drive home. I shouldn't get more that 8 or 9 PSI then I hope.

Anyone else that has any specifics on the hardware install?
I can figure out the settings in the box once i know i have things setup right...
Currently, i just took the hoses off the stock boost controller and hooked them into the corresponding connectors on the avc-r.
I must have read something wrong in that crappy Japanese to "Engrish" manual.

19psi is way too high. I keep mine at 15.85psi or 1.1 on the AVC-R.

Ok it comes with 2 pieces of hardware right? The pressure sensor and the solenoid valve.

For the pressure sensor I hooked up to the intake manifold. There is a brass connector on the intake manifold that is hooked up to the fuel pressure regulator. I pulled off the black tube and cut a short piece of the large black tube and hooked the short piece up to the manifold. Then, I put a T fitting between the short tube and the stock tube. Then I cut two pieces of large black tube, and I hooked the third connector on the T fitting to one of the new pieces, then put the air filter on the end of the tube, and the last piece of tube connected to the small air filter. On the end of this piece I put the pressure sensor. I used strong 2 way tape to stick the pressure sensor on the side of my fuse box, facing down.

The stock solenoid has 3 tubes going to it, you only need two. Just block off the one going to the inlet pipe. Then you just need to hook the solenoid up to the wastegate actuator and the brass fitting coming off of the intercooler side of the turbo.

I drilled holes in the left side of the engine bay and mounted the solenoid there.

I'm pretty sure that's all I did.

Default Thanks!

Cool Thanks.
I too tapped into the intake manifold hose and ran the pressure regulator off of that.
I didn't disconnect anything off of the turbo though and plug it. I pretty much just stuck the Apexi solenoid in the same place as the stock one. drilled some holes and mounted it. hooked up the two hoses and tried it out.

Did you do anything to the stock boost controller connector? i saw on some instructions that a guy put in 2 20ohm resistors. is that necessary?

Thanks Kenshiro for your help.
