idle and cruise logsIdle Log.csv Cruise Log.csv

Figured out what I was doing wrong for the boost leak test. Got that sorted and no leaks there. Did an idle log and a cruise log. I however was seeing feedback knock still up to -10 just driving in town not in boost, unfortunately didn't log that but it was between shift or in 3rd gear that I have noticed this spike in feedback knock. I realized my clutch is squeeking while pressing down and there are two plugs that I need to zip tie or something since they can move and rattle. I'll take a look at those this weekend and see if those are causing the external mechanical noise.

Thanks I'll look into a WBO2 when I get other issues sorted out. I think I am doing the boost leak test wrong as I can't build pressure. I have the turbo inlet connection to the pcv plugged and the oil fill unscrewed. Do I need to plug anything else? The pcv side I have the crankcase open to atmosphere and then the line going to the throttle body open to atmosphere. Do I need to plug that end? I am just using a bike pump to fill so it's hard to tell if/where I am leaking since I can't build any pressure.

Thanks for the input. Ill check everything over and see if somethingis rattling again. I also ordered a new pcv and inlet and will install those soon. I think after that Ill try to do the correct logs and then look at getting a tune. I don't have a wideband O2 any opinions on getting an etune without one?

Hey everyone, update: Installed new knock sensor Installed Grimmspeed TMIC Did boost leak test and all good. Checked exhaust connections and heatshields, all good. Currently have tank of gas with techron fuel cleaner in. First cruise around this is the log, skip down I am seeing -11.95 feedback knock not sure whats going on. I need some confirmation this can be tuned out and I don't need to do any other component related things first. I don't want to pay for an E-tune to find out theres other issues. Also I don't have a wideband O2, has anyone gotten an e-tune without one? datalog10.csv

I found an image of one with the end tanks off and it is just a rubber gasket sealing the edge so as long as that isn't torn, ripped, etc. clamping it closed in any way should fix the leak. Now to see if the gasket on mine is okay or not.

does anyone have the blueprint info so I can fab this up myself. I haven't heard back from anyone if there will be another batch or not and don't want to wait forever to get back to driving this car.

I will take a set if these come in stock.

Hello, Will this kit require a non-leaking oem TMIC or will it fix a leak I have coming from the short edge on the turbo side?

okay, ya I would rather be on the safe side of a tune, not trying to beat any records, just want a fun car for driving around. Okay I rigged up a very basic boost leak tester and I found out my intercooler has a small leak between the plastic end and the intercooler on the turbo side. Whats the best way to fix this? Or would I be better off with an aftermarket(which would be best?) and then get the car tuned?

One other question, I tried the 91 octane map yesterday and between shifts I am seeing feedback knock correction of -4 max what causes the knock between shifts is it just pulling too much fuel when I put the clutch in and getting lean?

Well thats good to hear a tune can sort things out. Really appreciate the feedback! I am probably going to get a boost leak tester rigged up to be sure thats not an issue and remove any rattles them ill get a custom tune. Thanks, this car will mostly be a summer car (couldmt wait till summer to start upgrading...) should I wait and get a tune when its warmer, or will the ecu adjust accordingly?

So looking at this again i missed that i am overboosting to 18.22 psi when the tune should be 16.5 psi. What are the causes of overboost that I should look at?

As far as mechanical rattle I do have a heatshield missing one bolt that I'll get tightened up however its not really "rattling". There are a few random bolts missing on random items that I'll try and tighten up. But from my limited knowledge so far the logs to me look like actual knock... but since I purchased the car after the turbo went on the previous owner I want to check hardware for issues too.(when I purchased the car it was completely stock, in retrospect should have added the accessport and figured out issues before stage 2 but...learn for next time)

Alright I attached a 3rd gear pull as well as a cruising log. First time posting logs so if I am doing something incorrect or missing values please let me know. Currently to my knowledge the boost leaks are fixed however I don't have a boost leak tester. I replaced the throttle body hose with a mishimoto and I replaced the turbo/intercooler O-ring/gasket with OEM. 3-3-17 3rd gear pull.csv 3-3-17 cruising.csv

I'll look around for any rattles. However would this show up when I'm not doing pulls? The pull I did yesterday I had -4 feedback knock during WOT 3rd gear pull. and when cruising had random fine knock learn around -1.2. I'm out of town and don't have the file but I'll post the log of the pull and cruising when I get back tomorrow. Thanks for the help in advance everyone.

Ill post logs tomorrow, thanks

My current next step after boost leaks fixed and fuel injector cleaner is to try the 91 octane OTS tune. If I am still seeing issues should i look at the fuel filter? Ill grab the datalog of ones i have saved when i get home tonight since that will help more than me explaining.

Hello everyone, I have been trying to get rid of some feedback knock and fine knock learn that is showing up on my stage 2 OTS setup. I found some boost leaks and am fixing those now. I also replaced the spark plugs with the ngk silfra6 plugs. Setup: 06 lgt sedan manual 88k miles New turbo vf40( previous owner blew it up, never changed banjo bolt) Filter removed from banjo bolt now Cobb catted downpipe Invidia catless uppipe Invidia q300 catback exhaust I used grimmspeed gaskets for all exhaust work Grimmspeed turbo heat shield Stock airbox and filter Cobb v3 accessport running 93 octane stage 2 OTS tune What would be the areas to troubleshoot knock next after I fix all boost leaks and have new plugs and clean the MAF sensor and I still see issues? I also have some techron fuel injector cleaner I was planning on running through next fillup. I am seeing -12 max feedback knock -4.2 max fine knock learn The DAM has not gone below 1 I definetely have knock when shifting but also during WOT in 2nd i see feedback knock around -6 to -12 and fine knock learn of -1.05 to -4.2. Since this run I havent done any driving in boost.

thanks, I'm going to go take a better look this morning and try and find the source of the leak.

Well, got my car back late Wednesday night. Dash looks good no issues there. However, I just got this car and on the way back from the dealership I filled up the tank for my first time. Fast forward to Friday morning when I open the garage.. I now have leaking gasoline from in front of the rear right wheel. I got the airbag recall and the brake corrosion recall. I contacted the person I bought the car from and they said they had the car in a garage recently with a full tank and no leaks. Now the part I wish I didn't do yet because I'm not sure if this could cause it but I installed a cobb accessport Thursday night after the car sat in the garage that day(I drove my other car to work). I installed the cobb accesport thursday night no issues(car is stock used 93 oct stage 1 map) I didn't drive the car Thursday night. But when I isntalled the Cobb accessport I remember smelling faint gasoline but not alot and thought nothing of it. Friday morning I open the garage to a puddle of gasoline and strong odor. Not sure if subaru screwed it up doing the brake recall or if the cobb install caused the leak, it says the test mode will cycle the fuel pump...could this cause leaking? But my dash looks great!......

Took lots of video and pics, and was told it would be done tomorrow afternoon. Hopefully all goes well.

Taking my 06 lgt sedan in today, was told two hours and the guy thought they needed to remove the dash...time to take a bunch of pictures and videos of everything working and hope they don't break anything.
