JamesJDMwagon Posted December 11, 2016 Share Posted December 11, 2016 What t-piece are you using to hooked your boost gauge up? Could be seeing too much pressure. It's only meant to sample. Quote Link to comment Share on other sites More sharing options...
stants Posted December 11, 2016 Share Posted December 11, 2016 When you say the gauge is up & down do you men it's going crazy on its own or is it fluctuating with revs ? Where abouts have you taken the boost gauge feed off ? Sent from my SM-G930F using Tapatalk Quote Link to comment Share on other sites More sharing options...
moshe_levy Posted December 11, 2016 Author Share Posted December 11, 2016 I use the OBD2 connector and see the boost on my phone at the Torque app. But the rpm up and down during the boost i see at the car rpm gauge.

moshe_levy Posted December 11, 2016 Author Share Posted December 11, 2016 Yes it is going like crazy lets say going up to 12 psi than down to 8 and up to 10 and i feel and see the rpm like there is no fuel,the car is hiccing up but only by boos (sorry about my english) Sent from my SM-N910F using Tapatalk Quote Link to comment Share on other sites More sharing options...
moshe_levy Posted December 11, 2016 Author Share Posted December 11, 2016 This is the T and the restrictor pill that i bought from the subaru dealer .the side of the pill i connected to the outlet of the turbo ,the other side i changed the hose to longer one that will reach to the wastgate and the 3 side i took to the elctric boost controler Sent from my SM-N910F using Tapatalk Quote Link to comment Share on other sites More sharing options...
stants Posted December 11, 2016 Share Posted December 11, 2016 No need to apologies about your English, it's all good ! 1st off I'd try resetting the ecu, as it may have been trying to compensate for the lack of restrictor, 2ndly I'd look at the Ebc maybe its causing a slight issue, can you disconnect it and see if it runs better without it ? Do you have access to a 4wheel rolling road ? be worth getting it checked in a dyno 1st before changing anything else, as if it's a fueling issue will be easy to spot there and save you money and time changing parts un necessarily, What grade fuel do you run on ?

moshe_levy Posted December 11, 2016 Author Share Posted December 11, 2016 Sorry but what is Ebc? And what do you mean by access to 4wheel rolling road? I was on 4 gear turn to 3 (auto trans) and when the boost rais it's happen Sent from my SM-N910F using Tapatalk Quote Link to comment Share on other sites More sharing options...
stants Posted December 11, 2016 Share Posted December 11, 2016 Ebc: electronic boost controler, For our cars you'll need a dyno that accepts 4wheel drive cars they will be able to check fueling and see if there's any flat spots in the map Sent from my SM-G930F using Tapatalk Quote Link to comment Share on other sites More sharing options...
moshe_levy Posted December 12, 2016 Author Share Posted December 12, 2016 Ok i understand you i will check all of what you told me.

stants Posted December 21, 2016 Share Posted December 21, 2016 Can you take a pic of your set up ? If all is well and correctly plumbed in from the factory i'd just leave it as is Sent from my SM-G930F using Tapatalk Quote Link to comment Share on other sites More sharing options...
moshe_levy Posted December 21, 2016 Author Share Posted December 21, 2016 I can't leave it just like that cause when it all connect like it should be the car not like it should be and on half throtle the boost goes up and down not stable and the accelaration isn't smoothly,now when disconnect that line the car got life. I will take some pic later. Thanks Sent from my SM-N910F using Tapatalk Quote Link to comment Share on other sites More sharing options...

moshe_levy Posted December 27, 2016 Author Share Posted December 27, 2016 Well.....sorry for bothering you guys but it came back today again when i'm pushing half throttle the boost get crazy up and down but when disconnect the vacum hose that comes from the T piece from the BCS every thin is ok, i think maybe it's the BCS itself the problem. Any one has ideas where to look and what? Sent from my SM-G610F using Tapatalk Quote Link to comment Share on other sites More sharing options...
moshe_levy Posted February 1, 2017 Author Share Posted February 1, 2017 Update.... After almost a month that i try to find this annoying problem i changed lines, put back the oem ic and bov,cheked for leaks and nothing,so today i decided maybe the bcs connect upside down so i told my self what the he....turn them upside down and waaaallllaaaa the car got life. Now i don't know what i did wrong but i'm quite sure that i saw the line come from the T piece goes to the upper hole of the bcs and the down one goes to the intake some where on the net,now i changed it and every thing like it should be. I have this BCS. Now when every thing is finaly ok i can go on with moding the car. Thanks Sent from my SM-G610F using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
