Can't log with VCDS and Ross-tech won't support..

[waxxonMTL]

So.. after having some issues trying to send some log to EPL, I gathered some opinion, but I decided to make a thread to gather maybe more information/suggestion.

I got tired and asked Ross-tech.. but they got me back saying I should read FAQ and pay them 99$ for support or ask my tuner to contact them... (instead of simply.. helping me right now -.- screw them honestly! lol)


Problem ; Seems like the sample rate isn't quick enough and the data doesn't look appear to be group UDS and/or Turbo selected (although they are)


Variable that could go wrong..

1) Parameters ;

I use 10 and this is what most people use. However, I have been told to not use more than 9 actually.. I want to believe that logging 8-9 parameters could yeild better result, but how come the majority log 10 parameters without problem and which one out of the 10 should I delete ?


Group 15 - Field 0 Vehicle speed
Group 25 - Field 0 Engine speed
Group 216 - Field 0 IGA_AD_1_KNK[0]
Group 222 - Field 0 Ignition angle; actual
Group 233 - Field 0 Lambda probes actual; bank1
Group 345 - Field 0 Air mass
Group 352 - Field 0 Intake manifold pressure
Group 556 - Field 0 Intake air temperature
Group 623 - Field 0 Charge air pressure specified value
Group 625 - Field 0 RFP_AV

* I do click on Turbo and group UDS so this is not the problem..

2) Software ;

I use the latest version of Ross-tech 18.3.0 ( if I remember correctly). So that can't be it.

3) Hardware ;

I run a old 6yr old dell laptop, core2duo, 4gb ram, win7. Since I know some people had trouble flashing their EPL tune because of the computer.. I would like to think that maybe it's hardware related. ( i.e: not quick enough to process all the logging hence why it appears to not be ''turbo'')


Any though ? I have a hard time believing I'm the first one to have a problem logging :(

Cheers!

I've found that with the newer version of VCDS if you log more than 9 parameters the sample rate sucks even with turbo and group uds.

Log 8 or 9 and you should be ok.

[infinkc]

So what exactly happens? Is your log file blank? Have you just tried to log like 1 file to see if it will even log at all?

[ojmcneill]

sounds like you're trying to log too many variables. As for Ross Tech not helping, sounds to me like you don't have their dongle. Can't blame them for that. Would you expect Microsoft to help you out with a question pertaining to your iPhone???

Maybe I'm off base but saying 'screw them' might not be the best ploy to get them to come running to help either, lol. That's just me though, lol.

Best of luck.

As mentioned, with the newer versions (after 15.x) logging with more than 8-9 parameters is hit or miss. The latest version actually did seem to log 10 fields for me, but the resolution was only so-so (a line every 3-400 RPM). So, what you are seeing is not just you.

The only real suggestions I have are to stick with 8-9 parameters, and definitely try a faster laptop. The speed of the laptop does make a difference.

There was some mention of changing VCDS communication parameters. That worked for some people, but it didn't seem to make a noticeable difference for me. These links cover the changes they recommend:

I've copied below what they sent me when I complained about this....

------------------------

I'm not aware of anything that has changed in terms of sample rates but
feel free to try using 15.7.3

Even if you haven't changed anything on your PC, it's possible that
something could be interfering with real time communication so it's
worth checking the items in FAQ 2.4 and 2.5

http://www.ross-tech.com/vag-com/faq_2.php#2.4

If you have a different PC you can try testing even on a temporary
basis, that should help eliminate any PC-related possibilities.

[Q5OnTheMove]

As JRan stated, try changing the communication settings.

2 things that helped me were using a more powerful laptop and also using the USB 3.0 port vs 2.0.

I upgraded laptop, usb port used, and settings jran stated and im getting updates in logs up to 12 times a second for 10 items.

Even with a pretty high end laptop(i7-4510U with 16gbs of ram) I still cannot run more than 9 parameters without it going a little wonky.

It has messed up my logs a few times.

[JD S4]

Wait, so people have said that you can only log 9 in most instances and instead of trying that - you made a big whiney thread and talked shit about support for Ross-Tech instead of simply reducing a paremeter or two..

Got it..

Carry on

If I called Ross-Tech to ask why the sample rate was really slow with their product and they wanted me to pay $99 for it, I'd talk shit about them too. It's their product, that they charge a *lot* for, and they need to support it. I know their support policies, but they still suck.

If he's using the latest version of VCDS, then he's using an official Ross-Tech cable. If he weren't, he wouldn't be able to use a recent version of VCDS.

Think you missed my point, Brother.

I upgraded to the latest 16.x version, and I was able to log 10 fields with decent resolution (not great but better). So, there has been some improvement for me over the past 2-3 versions.

[Loe]

I'm still on 16.8.1 (latest is 16.8.3), I'm downloading to the latest one now and will check later today if I can log 10 parameters. On the older 16.8.1, I would struggle to get ample reading with 10 parameters, but the sample rate was substantially better with 9 parameters.

[jran76]

These are my logs from version 16.8.3 over the weekend when I logged 10 fields with grouping and turbo. Keep in mind this is on the default settings over a 1/4 mile pass (so 12 seconds worth of data). Also, my laptop is a super cheap Lenovo (Yoga 11e) that uses a Celeron processor that I only use for logging (it's small, rugged, cheap and has a 128 GB SSD, so it's good for use in the car but not particularly fast).

[Q5OnTheMove]

I also have 16.8.3 version and when using turbo and grouping, I see anywhere from 9-11 milliseconds between data. This is with a i7 with 8GB ram and SSD drive.

Out of kicks and giggles I will modify the communications settings this weekend and see if I can get the refresh down to less then 9ms and report back.

What are there parameters for? I take the first one would be something related to ignition timing advance and knock? What about the second one?

I understood your point. I'm saying it makes no difference if other people said "Oh, if you just monitor less stuff, it'll work fine". If Ross-Tech doesn't say "you can only monitor 9", then if you monitor 10 and it's slow, he has a right to be annoyed.

He also has a right to mention it here, if he called the manufacturer/developer and they told him he had to pay $99 to be helped with functionality that *THEY* advertise.

[jran76]

Bypass valve

Yep. First one is knock correction in degrees for an individual cylinder. Second is the % the bypass valve is open. Check out the link above to my logging thread (in post #17), and it goes over most of the basic parameters.

[Kawoski]

I checked that PDF b4 but they look quite different for me since I'm logging a A3 2.0

Thanks anyway
