  1. Thanks! In some runs it's was a significant difference, but I couldn't tell if it was another factor (like launching at different rpm) or actual gains, so defaulted to the one that seemed the most accurate.

     

    I didn't realize how much time this car spends in sub 2,000 RPM range even. I'm so used to tuning for higher rpm's with my turbo cars, thus was really bummed to see NO gains 4k+ and thus would always just give up and go back to the stock tune.

     

    Part of me wants to fill it up with 93 again and make a tune that maxes that out, if there is significant gains then build the maps around that and use IAM pull back as octane based tunes. Forgot to mention, my current tune IAM has been sticking to 1.0 no problem!

    Mind giving a brief rundown of the setup you use to tune? A little while back, I tried to track down ECU defs so I could monitor with BtSSM (which I had used in the 05 OB XT that preceded this car). I recall coming close but never finding an exact match for my ECU ID 75221A7707.

     

     

    I'd love to make these improvements but I'm starting from scratch and don't have a whole lot of time available to play around.

  2. Thanks for the detail. Sounds like the SuperPro bushes should be safe. I'm not looking to make this Outback into something it's not meant to be, but I would like it to not feel like it's wobbling down the road.

     

    Any thoughts on similar improvements to tighten up the rear suspension without rebuilding the entire assembly with new bushings? If I hit a manhole or similar break in pavement with one side or the other, I feel the tail of the car shift it's weight to the outside. Not exactly confidence inspiring and nevermind what it does on a bridge seam in a bend at highway speed. I know the shocks and struts need to be replaced but they're worn, not leaking/damaged.

     

    I've had the car less than a year, 80K on it. Was at the dealer for an included oil change recently where I asked them to inspect and test drive. No damaged parts, and "drives like they all do". Great, thanks.

  3. Finally SuperPro released their 2010-2014 bushings. After waiting for them to arrive stateside, I was excited to get them in ASAP. The 05-09 Prothanes worked for a while, but have been creaking loudly for a while.

     

    Thanks for the details on these, and for the discount info.

     

    Do you have a sense of if the superpro LCA bushes restrict wheel travel towards the end ranges? I don't go rock crawling or anything close to that in my '11 OB, but I want to avoid an overly stiff bushing (compared to stock spring setup) that might send too much stress into the frame mounts.

  4. In skimming back through this thread, I didn't find anyone else's log showing timing (but I probably skimmed right over some, sorry about that). I wonder if anyone who has looked at these things can say if the logged timing data I'm seeing is typical. Looks like odd behavior to my untrained eyes.

     

    The log below is with the car at ~190°F, stationary and in neutral (manual trans). Idle is lumpy but steady at 750 RPM, then starts misfiring more sharply when I bring the revs up slightly. Timing is bouncing around during the former, then sets dead even during the latter. What gives?

     

    I'm lining up for some more diagnosis this weekend: swap coil packs, check plugs, compression test, test crank position sensor, check for vac leaks. I'll likely run a can of seafoam through the manifold for good measure.

  5. I've read through and have been following this thread, as my recently acquired 05 XT has a no-code misfire on cyl 1 that I've been whittling away at as time allows. Great info in here and thanks to @StkmltS for letting the scope expand a bit along the way.

     

    Thanks to @heiche for BtSSM related hardware help. I learned about BtSSM through this thread and got it up and running last week. Excellent program.
