    A long chirp or whistle under boost

    I have a strong feeling this noise is ethanol related. I have done a lot of driving this weekend. I had the back full with Ike.a furniture and the wife along for the ride too. It was cold and rainy so the temperature element was there. It was optimum conditions for replicating the noise. I...

    A long chirp or whistle under boost

    Regular premium trims are usually tight. I will have to fill up by this weekend. I will have a full tank of shell 93 tomorrow morning. How do we proceed? Flash the COBB OTS 93 with dtc codes fixed for the FF kit? That way we are looking at the same thing to start. I will email you the complete...

    A long chirp or whistle under boost

    Log sent. I wasn't sure what type of driving you wanted to see in the log so its my ride home with some aggressive driving when appropriate. I have a tank full of E70~ right now.

    A long chirp or whistle under boost

    Could this be the hpfp whining about ethanol? I haven't read anything about a noise in relation to this cam driven pump. Its definitely coming from the front drivers side and quite possibly from up top. I'm sure the hoses are on correctly and tight with breeze clamps. TMIC wasnt cracked or...

    A long chirp or whistle under boost

    I would say it runs consistently throughout the gear run. No sag or surge in power. Another odd thing is the RPM marks that the noise occurs during, the sweep through 4k and 5k RPM. This is a very consistent variable. I changed the clamps to breeze clamps and snugged the turbo housing couple...

    A long chirp or whistle under boost

    If your wondering if any part on the car is stock, yes. FF kit and AP are the only mods. Fuel pressure is solid. I had a log from the video run but in my haste i forgot to select RPM...give me a list of what you would like to see in a data log and I will get one. This kinda sucks being my first...

    A long chirp or whistle under boost

    There has to be a load on the engine. The video is with the car running an E60 blend. I'm at an E17 blend now and it seems to have somewhat subsided or at least require more load to get the whistle. Not as loud either.

    A long chirp or whistle under boost

    Yes first turbo charged car. It is more like when your trying to whistle and it doesnt go right kinda. I have breeze clamps fot the intake tract, I will be doing those this weekend. I should check for exhaust leaks while I'm under there.

    A long chirp or whistle under boost

    Yes from a 45mph roll on in 4th gear but only one instance of the sound with a "not quite WOT" input, so there is a threshold that has to be reached to hear it twice. Maybe from 75mph in 4th, but the onset of good boost is much faster, spending less time in the whistle zone conditions. I would...

    A long chirp or whistle under boost

    Front driver side (j pipe side) best I can tell. Yes @ running temps. Fully warmed up The FF kit is just a sensor basically (WRX not STI). https://www.cobbtuning.com/products/fuel-system/subaru-flex-fuel-ethanol-sensor-kit-wrx-2015-2019 Yes above 3k. This is not the same car but the tone and...

    A long chirp or whistle under boost

    If I lay into it in 3rd or 4th, along with the normal turbo sound, there is a noise that happens twice during the gear run. The sound is not high volume, has a soft start and end, and seem to happen after spool up and right before peak boost. Is this the waste-gate making the noise under certain...

    2015+ WRX MAF Scaling attempt accesstuner

    I don't see tables that would directly adjust pulse width. It seems to be a given value not available. Or am I blind and its right in front of me.

    2015+ WRX MAF Scaling attempt accesstuner

    I had attempted to do a CL MAF calibration by logging, adjusting, loading new MAF table values, log some more, check/adjust. But I found it much more fun to do it in accesstuner live. Its hard to hit some of the cells though, long enough to get good learned values. When a learned value is steady...

    2015+ WRX MAF Scaling attempt accesstuner

    Hey thanks for clicking on that link! I'm looking for some sage wisdom on CL MAF scaling with accesstuner on a stock 2018 WRX. What it seems like I'm doing is doing a best fit with the MAF sensor while holding injector specific parameters, variable valve timing, ignition timing, and stock...

    Air/Oil Seperator. Your thoughts please?

    I'm considering a catch can so I can avoid tapping into the coolant system. Is it reasonable to check/empty the catch can every oil change or are more frequent observations necessary? Looking at http://www.radiumauto.com/Dual-Catch-Can-Kit-Subaru-02-142015-STiSaab-9-2X-P817.aspx
