    Finally got Cryotuned, How about you?

    Hey Dave, sent you an email to apologise for the (numerous months) delay at getting logs back to you, was in a JetSki accident and haven't been driving too sore still, hope it's not too late to get logs back to you sorry for the mammoth delay!

    New Hog-zawst System!!! The sound of power! *with patented washer technology*

    in Walkthroughs :: Performance Modifications

    Posted · Edited by chimera

    So what's the "paid" alternative (eg: > $1 of washers) - replace the rear mufflers in order to get a better sound? If so what's available for this? Anyone got vid's / sounds they can post? Not a fan of the "hogzaust (aka "hole-n-zaust" - and no disrespect hogmeat, the idea is simple but I'm not 18 years old anymore trying to pull pussy with 60 cents worth of washers) I want the boxer rumble noise and preferably a nice exhaust note when I ring the shit outta it, but preferably don't want an annoying drone at idle or cruising.

     

    I got to drive a Lamborghini Gallardo around a local race track yesterday, if anyone can get a Subby to sound like that for < $200 they'd be a rich man lol!!! That was 550HP of pure sex on wheels.

    Dave has offered to re-work my e-tune after stumble issues on the first round of tuning. So far (at revision 3 of the re-tune) the car is responding *considerably* better than before and so far, with no stumble.

     

    That is literally top quality service - someone who actually takes pride in their work and is not happy until the customer is happy.

     

    I'll get the next lot of logs to you tonight Dave. So far, I'm well impressed by the new tune. Thank you so much!

    *** Knock, do you have any?

    Before attempting to read from or write to ECU using ECUFlash, you must make sure the GREEN test leads are connected under the glove box and passenger side carpet. Once connected and when ignition is switched to ON you'll hear the radiator fan turn on and off over and over again, until you press read or write on ECUFlash, then the fan stops.

    That's the procedure I have to follow on my USDM LGT, I'm tended to assume that the same applies to JDM vehicles

    Not always true. I am gathering this is true of some models, but not all. My '07 JDM (same as '08 USDM) using Tactrix / Canbus, does not need green connectors plugged in. In fact, plugging these in STOPS it from working. However giogio43 might be in the same boat as you, since his is also an '05 model.

    logging didnt help i dont understand when i try to select parameters in RR its completely different to what people write about logging those knocks. knock sum, IAM an so on my RR does not have it.

    how am i supposed to log and figure out why IAM is at 0.64 if i cant log this knocks or whatever. what should i log then?

    Many logging parameters are unavailable UNTIL you connect to your ECU using RR. Once connected, then enable parameters. What to log... hmmm, perhaps start first by reading the entire thread on this same forum "Knock, do you have any?"

    So yes, knock can be real knock, or it can be false knock. But the ECU always err's on the safe side. IAM is a generic knock

     

    when i start engine then run LV and hit connect i get some data out right... so is the software now connected and if i drive around aggressively ill see some changes?

    No. LV is a "point in time" snapshot. The fine learning knock correction or "FLKC" (figures in the large table in LV) show how much knock the ECU is learning at various engine load / rpm's via the knock sensor. The IAM (top right in LV) as mentioned before is a "generic" timing advance - if the ECU sees FLKC changing in alot of cells, then IAM will be lowered (eg: timing is pulled) Conversely, when IAM changes, then all FLKC values are cleared so it can monitor knock again (and so on - so IAM can get lower and lower if knock is real bad). If the engine is running on good octane fuel with a good tune, then IAM should sit at and stay at 1.0. So yes the FLKC values do change (in that they are "learn't") but you would need to click 'Connect' each time to refresh the LV. You need to run RomRaider instead and log output of the various parameters. LV is just a helpful tool to get a real quick overview of the general state of health. It by no means covers everything.

     

    you do need some special education to understand all this

    unfortunately yes. i've still got a crap load to learn myself.

     

    EDIT: few month ago subaru shop logged my car and they told me SPARK plugs need to be changed... why does LV not show me that?

    Because there is absolutely no sensor that can categorically say "problem ABC is caused by XYZ and XYZ alone" (the sensor can tell the ECU and you'll get a CEL, but the point is the cause of that problem could be due to a number of areas) hence why we log to determine this, there are just so many variables involved (add a turbo, and the number of variables increase exponentially!)

    IAM should be 1.0 whats that?

    Ignition Advance Multiplier. Its a generic timing advance for the engine - timing gets pulled if problems are detected,... why? To save your engine from going bang bang.

     

    what must i do
    You must search these forums young Jedi... I'll give you a clue.

     

    Knock knock.

    Who's there?

    Knock

    Knock Who?

    Knock is likely causing low IAM

     

    Start by using a better quality and higher octane fuel (less important for NA, but a good start)

    romraider only works with 32 bit java - in their troubleshooting guide, it clearly states to remove all versions of java first before installing, then install latest java 32 bit and proceed.

     

    I think LV 1.0 RC3 is latest here http://www.romraider.com/forum/viewtopic.php?f=32&t=7397

     

    You are logging - it says so in your screenshot. check for a CSV file that its created and open that in Excel. to make it "safer" to start/stop logging (eg: not clicking on a notebook while driving) hit the demister button. that'll kick it into action. otherwise, for a realtime visual view, click the Graphs tab at the bottom.

     

    EDIT: oh, sorry iNVAR didn't see your post above.

    1. Are you using the stock or aftermarket intercooler?

    2. Which brand and grade gas are you using?

    3. Which Oil are you using?

    4. Geographically speaking, are you on the East coast or West coast?

    on stumble, logging shows wgdc and timing drops to zero and idc drops from 75 or so to 2.85. watching boost gauge, psi drops from 18 to 12 in a split second. its like a total fuel and boost cut. heiche is possibly right, in that its going lean and cuts out - possibly intermittently inaccurate sensor voltage or mechanical issue, maybe actuator or bpv does get stuck. who knows. what's bizzare is it doesn't always happen - letting the car shift from 2nd to 3rd, or from 3rd to 4th sometimes happens, sometimes doesn't (generally won't happen if it shifts up and is above 5,200rpm's, if shifts and slightly less than 5,000rpm's, it'll stumble). I can replicate it every time if I shift myself though (tiptronic), slightly before redline (so rev's on the up shift are < 5,000rpms). anyways, dave @ cryo is onto it and analysing logs right now - I have utmost faith in him!

    Using an Autonostics/Vag-Com Cable To Read/Flash ECU's

    Means whatever port that the driver says it's using in device mgr, make sure you got that port selected in RR or ECUFlash. Yes baud rate is speed, try 9600 - although having this wrong would generally give you scrambled data rather than ability to connect so I'm speculating here. Post a pic of device mgr showing driver installed and com port info. Also, test a connection using LV I found that this worked with my car and vagcom but not ecuflash or rr, but tactrix could do all 3.

    ignore the green cable.

     

    control panel, device manager - under ports does the device show its working ok? is the com port the correct port related to the driver? have you tried altering baud rate on it? you can't have both app's (romraider AND ecuflash) connecting at the same time too, use one at a time.

     

    EDIT: dude... post once and once alone. http://legacygt.com/forums/showthread.php/using-ebay-vag-com-cable-datalog-96737p31.html multiple posts of the same question won't answer your question any quicker.

    I've emailed my logs to Dave after a few runs late last night. I did notice when the studder happened, the boost gauge (which I've just installed) showed boost dropped from 18psi to 13psi within a split second.

     

    I will do another test tonight where I'll go hard on acceleration through 2nd as per usual, change into 3rd but just before around the 5,000rpm's (where it stumbles) I'll ease off and pull through the rev range a little less aggressively and see if it still does it. Need to see if its just in WOT or if the ECU balances shit out if I ease into high rev's when hitting 3rd. Its almost as though the fuel pump can't keep up with the rate of gas being consumed - like a complete cut to the injectors for a split second. PITA and getting a little pissed off with it now.

    Go ahead and send me an email like I mentioned and we can take a look at a few things. The fact that it happens on two 100% different tunes on different cars with different tuners/transmission types/mods etc makes me scratch my head as there are not a lot of common driving factors there

    Exactly! That got me kinda happy because 1. I was not alone :D and 2. it ruled out my transmission and 3. we can potentially run logs on both cars and do some comparisons (when he's back to IAM 1.0 of course)

     

    Both car's are 2008 LGT's (JDM), however his is spec B manual mine is non-spec B tiptronic (not that spec B should make any difference) Will be interesting to see what turbo he has too, from memory mine was VF44. His IAM is crap for sure, and thats something he will need to work out first. I will find out if he has a copy of his stock ECU and perhaps remap back to stock and try it out. Will also see if I can get him to take it to the mechanic and check for sure if he has an aftermarket DP installed (unless there is any easy way of telling? at a glance I couldn't tell)

     

    Sorry haven't got the logs to you yet - every night there has been something on... got the kids tonight as the wife is out... beer o'clock...
