    COBB SF, silicone afta-maf and inlet, is this my build thread? hehe...

    the scaling was really close to stock when I did it the first time. I've been playing around too much to remember which map I have that on. I'm a sloppy technician, need to take notes and all that.

    I did make one or two short scaling runs before I flashed the testes map.
    On LV the AF learning looks ok, 5 or under in all blocks. I'll post it up here tonight just to show you guys.

    What I was seeing in my logs is that when AF Learning #1 jumps to -10 sometimes -25, I'll have knock. Once when it jumped to -25 I had two incedents of knock, pulled 2 then 4 degrees. That's what's got me worried.

    Still think I have an exhaust leak. I tightened everything but the bolt under the turbo/downpipe, the uppipe to turbo bolt - I did get the other two they were torqued good when I went to re-torque.
    I might seafoam it again to find the leak. The is so fustrating. My WRX has had exhaust leaks ever since I bought it. Starting to sound normal too me. I should have had zax or somebody at the MEAT listen to it for me.

    from today heading to work...





    from 2013-03-15 heading to work...



    the last one was before I pulled some timing in those slight knock areas. 16 IAM, that's what the initial value is so it's not dropping.

    also did some slight scaling between the latest one (top) and the earlier one (bottom)

    New one doesn't look bad. Drive around a bit more populating 50+g/s and see what happens.

    When you fix the exhaust leak, you'll need to revisit this again, likely.

    yeh, problem is as soon as I drive around knock-iddy, knock, knock...

    the latest LV only has at most 20mi of DD to work and back. 10-15 min drive to work, speed limits are 15, 35, and 45. So yeh it's kinda hard to get in the 50+ area on a work run. Once I get as many knock events fixed up I'll get up in that range.

    I might got for a logging run tonight.

    I've been pulling timing here and there to squash the knock. No joy.

    IAM dropped to 8 this morning. Arg... Need to look at fueling now. Think I have issues with CL/OL transition. Gotta find my thinking cap...

    yeh well this is what she said...

    this guy is a little frustrated because of this and I kicked my tactrix cable one too many times just before is does this...

    and yes IAM initial value is set to 16 on my current map.

    The RPM/Load cells you pulled timing from, it was easily repeatable, correct?

    I was logging to and from work mainly because that's the majority of my driving. I logged for a few days and compared the logs. I didn't pull timing for the random ones, just the ones that occurred on at least two logs.

    Easily repeatable? Didn't try that. But the multiple logs taken in roughly the same conditions on the same route might count for that.

    Ordered a new Tactrix cable. Got the OBD extension too, don't want to karate chop another one. Current Tactrix still works, just dropped connection a time or two on a logging run. USB connector is bent. Don't wanna brick me ECU with a dodgy connection...

    Once the new one comes in I'm re-flashing the base map EJ257 pointed me toward. I fudged something up on it and didn't take notes.

    I would start making sure everything is proper mechanically.

    I am about to start pulling my hair out.

    Might as well pull out my spark plugs and look at them first right?

    I've been on top of my maintenance. Plugs have like 10k on them at most, oil gets done before 4k, all exhaust gaskets are fresh, nothing is loose that I know of. I cleaned my air filter(COBB) then my MAF a couple of days later.

    enough.. to the toolbox!

    dug around my engine bay for a while. couldn't find anything loose or leaking. pulled a spark plug and it looked ok.

    my new tactrix cable came in on Sat I didn't even check the mail or the tracking number...fail.

    anyway flashed it back to my old map. It never dropped IAM on me. I'm going to do the work and back log a few times for a sanity check then off to do some pulls. So next couple of days I should be sorted.

    what heatsoak?

    initial IAM on this map is 14 so it climbed a little. HOORAY! I did see a touch of knock on one of my 4 work and back logs. I'm going to keep logging and see where and if I need to pull timing. I think I need to work on fueling too. 10% eth maybe what she's drinking...
