  1. General Maintenance, Troubleshooting & Accidents.
    First off, I drive a 2019 Wrx and I've got the Grimmspeed cai and 3port ecbs installed with a stage 1+ street pro-tune, tuned by a reputable tuner in my area. I got those mods installed and the car pro-tuned in the beginning of May, of this year and at first everything was great! After about a...
  2. Maintenance, service, and repair
    Hi, I’ve been reading for this forum for a while now but never really decided to make an account until now. After work yesterday I noticed an odd loud knocking noise coming from my engine on cold start. Unfortunately I had to drive it home because I had no other option available at that point...
  3. General Maintenance, Troubleshooting & Accidents.
    Yesterday I was doing gravel donuts in my 2017 Wrx. My DAM dropped to 0.75 and my FBK and FKL both start to move around when the throttle is about half open. Idle and WOT show no movement and they both stay at 0. If anyone has any tips please let me know. I am very new to the car scene. Thank...
  4. General Maintenance, Troubleshooting & Accidents.
    Hey y'all. This is my first time ever posting in this forum. I'm new to car stuff and just recently installed the cobb redline cold air intake and the accessport. I'm running the 93oct stage 1 OTS tune for now. It was running just fine for the past week after installing. Never seen the DAM get...

  6. General Maintenance, Troubleshooting & Accidents.
    Sad day...I bought a 2013 wrx hatch 4 months ago and just yesterday I drove it for 2hrs on the interstate, during the last 10min of the trip I started to hear a quiet tick that got faster proportional to rpms, however the tick only happens after 2200, can't really hear it below that. I...

    Mod List: Tomei Expreme Catless Downpipe Invidia N1 Titanium Cat-back HKS SSQV BOV Cobb CAI Cobb Accessport w/ Ricky Silva Stage 2 (93) To start off, the past week I've been loosing around 3-5 psi of boost at around where peak boost used to be. I attributed this to the difference in temperature...
  8. General Maintenance, Troubleshooting & Accidents.
    Hey everyone, I've been seeing Feedback Knock upwards of -11 ever since I got an AP this past December. Bought the car in November. 2010 WRX w/ 100K+. Stock intake and tune. I was able to get a good log tonight (attached) going from stop light to stop light on my drive home, where I saw...
  9. General Maintenance, Troubleshooting & Accidents.
    Yesterday I noticed a very loud knocking or clicking sound coming from my ‘15 WRX. I’ve narrowed it down to the driver side of the engine but that’s as far as I can get without tearing apart. So far I notice it during start up and acceleration. Sounds a tad like rod knock but today after trying...
  10. Maintenance, service, and repair
    So my 2005 wrx I just noticed a faint knocking. It’s stronger than a tapping noise but not as strong as a knocking if that makes sense. It doesn’t happen at idle only when I start climbing the RPM’s. Hoping someone could help with some ideas. I was thinking maybe the timing belt skipped a tooth...
  11. Maintenance, service, and repair
    Good afternoon, I own a 2015 WRX, Stage 2 (Cobb 3" exhaust, OTS Stage 2 Map using Cobb V3 Accessport). I've always monitored regular feedback knock, it comes and goes (the high negatives). I've driven this car (stage 2) for months now, I've just changed the oil and had a friend who is a...
  12. General Maintenance, Troubleshooting & Accidents.
    2005 Subaru Wrx - 162k miles Cobb stage 2 on 91oct Over the past few months I've been seeing more and more knock reported on my Cobb AP. Recently the DAM dropped to 12 (from 16) which I saw as a cause for concern. For fine knock learn (FKL) and feedback knock (FK), ive been seeing values as...
  13. General Maintenance, Troubleshooting & Accidents.
    Hey all, figured I'd come to the Subaru guru's and ask this question. When I take off, even babying the car, I can hear an audible clunk/knock. Also, sometimes when I shift I'll hear the same clunk/knock. I was thinking engine mount(s) or transmission mount(s) or both. The vehicle also shakes...
  14. Tuning: Electronic Engine Management
    I logged some parameters today and i found that the FBKC is not "0" but FLKC is... is this bad? im a total noob looking for help, im attaching the fine learning knock correction table of my car if it helps. Thank you very much. Car: USDM 2006 WRX TR, "Gabedude Stage 1 R30", 91 oct...
  15. Engine Modifications
    Intro: just bought a 2002 WRX wagon 133,000 miles, with rod knock for 4k, with 5k left to spend on the repair. If I do it in my own garage. . Though I’ve never done a Subaru, I have done plenty of builds in the past, and am fully excited and capable of doing the swap in my garage “I believe.”...
