Morning,

I am struggling to do some efficient logging on my 3.0TDI as the .4samples/sec is just too slow with my HEX-USB+CAN cable.

Does the newer HexV2 have better sampling rates or is this a function of the ECU?

Just don't want to buy a new cable and not have it fix the problem!

Hello
Please post a full autoscan so the Ross-Tech engineers can see exactly which ECM and other modules are on your car. That will give them a better idea of any time improvements you might get

Best regards
Derek

Does the newer HexV2 have better sampling rates or is this a function of the ECU?
A HEX-V2 may be somewhat faster, but the improvement won't be huge because it is largely a function of the ECU.

How many measuring values are you logging at once? Each one requires a separate request -- unless you use "Group UDS request". Also, have you tried the [Turbo] button?

The turbo button just leads to VCDS crashes, not 100% sure on that one.

Also when I click group UDS I get a message saying device doesnt support function, or something similar.

I don't have access to a 3.0 TDI at this time to compare a HUC such as the one you are using with a HEX-V2, so I can't give you any solid figures.

What is it exactly that you're trying to log?

I can test it for you if you want to send me one :)

I'll even buy it if it works tangibly better.

Yeah, you cannot group that many UDS requests (12), and the HEX-USB+CAN doesn't allow you to split the grouping. I expect a sensibly better sample rate with that set of measuring values and a HEX-v2 with group+split requests.

is split requests just doing multiple logs or is that a feature of VCDS? I saw the grouping box but not another for split requests.

better yet the question I should ask is how do you advise I log this setup with my existing hardware, and if I upgrade to a V2

With your current hardware I don't think you can get much faster than what you're getting currently. If you get a HEX-V2, you'll be able to log all 12 values at the same time, and you'll be able to group them in the best possible way (typically group by 7 or by 8). I understand this is difficult to visualize, so here's an imgur album:

You can either click on the link or use the right arrow to see the next picture.
First pic is what you can currently do with your HUC: 0.8 samples/sec (sps)
Second pic is what happens if you try to group 12 requests, it's denied by the ECU.
Third pic is what the v2 lets you do, split the grouping in 2 groups of 8 and 4: 6.6 sps
Fourth pic is using the "bypass windows timers" on top of grouping, if your PC is powerful enough: 9.1 sps.

I do most of this on a surface go 2. 4cores@2GHZ and 8GB of ram.

What kinda of processing power do I need for the bypass windows timing, or is it more trial and error
?

Thank you for following up, this is yet another case of "whenever I have a question, if I look hard enough someone else has already asked it"--but just because it was asked it doesn't mean there was ever an answer! Much appreciated.

The maximum number of VCDS cables to sensibly own is always n+1 :)
I'm probably about to order #4, it might even be #5 if I still have an ISO-COM in a box somewhere, but I'm sure there's a limit somewhere... right? (Realistically though I'll probably sell some given that it looks like the street prices for older interfaces are high enough that I can unload my HEX+CAN and Micro-USB, buy a real supported HEX-v2, and have a ton left over for beer. The KEY-USB can stay and live in the '03 wagon full-time, nobody wants K-line interfaces anymore!)
