    Please review data log - Stage-1 93 octane, Stock Intake, Stock Exhaust

    Hi All,

    I just install my Cobb v3 today and I did a short data logging, can you please review it and let me know if anything needs to be changed?
    I'm running a 2013 WRX Sedan - Stage-I 93 octane, Stock Intake, Stock Exhaust.

    Current Cobb Map: Stage 1 93 MTv300

    Thanks for the help!

    Looks ok, but that's pretty poor resolution. What gear did you do the pull in?

    I was on 3rd Gear. What do you mean by poor resolution?

    Your log contains 35 rows of data. When I do a 3rd gear pull my logs contain about 200 rows of data. You can delete some of the parameters that aren't as crucial to maybe improve your resolution.

    Oh that's because I accidentally shut it off at my peak boost, so what you actually see is only the acceleration but not the declaration. I guess I'll have to make a new one and repost.

    Werd. I still think you could get better resolution. Another way to put it: Looking at the "Time" parameter, your log reaches 1 second with 3 rows of data. Mine has 16 rows of data by the time I'm at the 1 second mark. More data is always more better with these things.

    Your log looks to be fine to me, btw, but if it were me I'd want to have more info.

    I see what you mean by "resolution" now, I'll try to create a new log correctly this time and submit it again. Thanks for the help!

    Log is clean.

    For your next log, remove the following parameters:
    1) AF Learning
    2) Dynamic Adv ()
    3) MAF (g/sec)
    4) MAV Volt

    You can't expect anywhere near the resolution Will has by using your Cobb AP (Will is logging with an OpenPort 2.0 cable and a computer program called Romraider); it just isn't capable of it. However, removing those four parameters will help a little bit (but not much). As for the "deceleration", there's no point in logging that, as your injectors shut off and the car basically becomes a simple air pump.

    Ah...didn't catch that it was with an AP. That's why you're the tuner and I'm just some drunken fool.

    Easy well to tell quick in the future: DAM vs IAM (DAM = Cobb / IAM = OpenECU)

    Just ran another log on a 4th gear on the Florida Turnpike.... please review:

    https://dl.dropboxusercontent.com/u/...g6-wrxbuzz.csv

    I am having a peak boost of 18.14 but that's on a 4th gear, should I try to run a low wastegate map or is it still within the normal margin?

    What do the Cobb map notes say?

    RTFM I get it... ...BUT!

    "LWG: Lower wastegate duty cycles (LWG) for use when normal wastegate calibration produces higher
    than targeted boost (i.e. over boost)."

    I'm currently running this map:

    Stage1 93 MTv300
    o Fuel Requirements: 93 - 94 octane or better
    o Intake Requirements: Stock airbox with stock air filter
    o Exhaust Requirements: Stock exhaust or upgraded cat-back exhaust
    o Boost Targets: ~16.5psi peak boost pressure tapering down to ~13.5psi by the 7000RPM redline, +/- 1.0psi


    But it doesn't say how high or low type of boost, does 1-2 PSI over requires a whole new map level or is it higher than that?
    Also, I tested it on 4th gear this time. My previous test was on a 3rd gear and produced a peak boost of 16.79 which is normal.
    So I'm a bit puzzled.... Should the boost stay restricted to 16.5 at any gear whatsoever, or does the settings only apply to a 3rd gear test?
