    Strange code won't go away...

    in Fifth Generation Legacy (2010 - 2014 )

    Posted · Edited by SJGT

    so just had this p0024 code fire as well, and i'm just off 2 variables...

    1. had the car sitting for a decent amount of time as i'm working from home

    2. just completed the turbo back exhaust, it had previously only been downpipe

    to stock catback

     

    code fired on the way home from that install. The car has not yet been retuned after the exhaust added. Car idles fine, car was running/driving fine, though it did just cut out on me as i was pulling into have the oil changed.

     

    I went through the screenshot someone attached, step 1 had me move onto step 2, being that @ idle the AVCS Exh L and R both stayed @ 0.

     

    when i did step 2, it seemed as though the AVCS Exh L was inconsistent with the others, appearing to spike higher by roughly 150% throughout the cycles, what's this mean? the below #s are just via cobb's peak reporting.

     

    AVCS Exh L = 45

    AVCS Exh R = 30

    AVCS In L = 30

    AVCS In R = 30

     

    So oils been changed, codes reset and car has driven fine since, no codes, but only toiled around town for an hour or so. I did however notice a lot of inconsistency from the AVCS Exh L at this point, at times high like it was before, but then at one point it was settling @ 0 while the others all stayed more or less in sync with each other during driving - what if anything does this mean? i'm lost on this level of data and it's paralyzing me cause i don't know what's bad, real bad, or meaningless/standard

     

    so I can have the shop check o2 sensors? or should i just order and replace that AVCS solenoid assuming that left side one is fubar'ed. Wanting to understand what i can lock in on based on those #s. Or is this something else i can data mine for?

     

    I was supposed to take the car to VT tomorrow, not gonna have time to settle this all out i don't think - at this point hard recommendation to resolve before any significant mileage, right?

    So it sounds like this is a backwards way of controlling boost, effectively allowing what we believe is the overboosting downpipe to get me up to target boost even at base actuator spring pressure - that would possibly lead to spikes in EGT (among other things?) I'll start logging this to review - what's an acceptable range for EGT? And what's the downside risk of spikes in EGT - what else would I want to log to see the risk of a tune like this?

    Aaaannndddd.....your tuner didn't say anything to you? I wouldn't trust that dude farther than I can hock a loogie.

     

     

     

    And just to be transparent - I'm sure a quick read of my involvement in this forum it's pretty apparent I'm a serious noob here - I'm learning a ton as I go - really serious learning curve - I didn't exactly ask many questions either when I picked it up - now, that being said - for the price I paid I would have appreciated some 1:1 with the tuner to learn about what he saw and choices he made - that didn't happen either - so from here - we look at my logs - I ask questions - get some answers - and we keep learning - whole reason I kind of jumped headfirst into this was to add some more value to the forum when I didn't have my own knowledge yet to share - can at least use my experiences and risk appetite***

    a couple logs I was able to get today - conditions aren't really great so I couldn't really get a good pull in, and looking lousy for next few days - heading to baltimore on Tuesday/Wednesday for work so maybe a couple highway pulls on my way down there - but either way something to chew on for a bit

     

    datalog1 - 3rd gear pull from 2500 to 6300rpms and let off - reached peak boost 16.9 in the 4800-5000rpm range

    datalog3 - 3rd gear pull from 2500, shifted into 4th at redline and just got on it a touch more from there

    datalog4 - 4th gear pull from 3400, let off it around 5600, hit 17.9 around 4800rpm
