Any one dare to get a VCDS with HEX-NET Professional USB & WiFi Interface

[DV52]

Interesting that it's that much faster? How so? Just more responsive? I would have thought that the limiting factor was teh OBD port rather than the adaptor.


I got my HEX-USB+CAN cable back in 2010 (I just looked up the receipt and note the price hasn't changed either) for US$349 + shipping bringing it to a total of US$408.09. The dollar was near parity back then too

Since then it's been plugged into many (many many) different cars from people visiting for little tweaks here and there. I don't think the 10 VIN thing was even an option back then. Honestly, money well spent for what it's done over the years.

The_Hawk: Hi again - First, I must apologise if I have not been sufficiently clear - English is a cow of a language in which to express any assertion and alas it has a second disadvantage of being it my second language !!

So, to be clear- I'm not saying that there is anything wrong with HEX+CAN cables. But - and there is always a but - the design of HEX+CAN cables must be some where around 20 years old now and as was demonstrated in the "Ross-Tech" firmware patch that was needed to fix the compatibility problem with MIBII, the design of HEX+CAN cables is approaching its limit as VW's control modules become ever more complex and ever more up-to-date!!

HEX+CAN versus HEX-NET - A SPEED TEST!!

As far as my claim about the relative performance of HEX-NET versus HEX+CAN (still a good cable), perhaps an easy way to demonstrate this is through the simple process of an autoscan.

So Here's the broad basis of my speed-test: I've just completed two auto-scans on my mk7: one with my HEX-NET cable and again with my HEX+CAN cable. For each run, I have tried to keep all the variables the same (i.e. same car, same laptop, same RT version software) - the only difference was the cable.

Unfortunately, VWW's word limit policy won't allow me to post-up the full results of 2 x autoscans (in the one post), but here's a cut-down section of the auto-scan result using my HEX+CAN cable

The important part of the auto-scan is the last line. HEX-NET was almost three times as fast as HEX+CAN in polling the 14 x control modules!


OK- the difference between 3 minutes and 1 minute isn't much in terms of actual elapsed time - I hear you saying! Very true, but it does mount-up!

But the real performance difference with HEX-NET becomes abundantly clear when completing adaptation channel maps for control modules with large channel-count. Here's a god example with the BCM from my car which has a channel count of about 1,800 (and this is for a mid-level BCM)

Again, I can only post a cut-down portion of the admap because of the word-count limit! Note a previous version of RT software was used for this admap

Yes- it's true: Just 01:42 to poll every possible channel in the BCM and to return about 1.800 entries - man, my HEX-NET runs like a cut-cat!!!

Hi Don,

I have a mate who is looking for a second hand HEX-USB+CAN, if you do decide to sell give me a shout.

TonyB

TonyB: Thanks for the reply - As I said, my trusty HEX+CAN was my first OBDII "love-affair" - I still have to go through the 5 stages of grieving before I make such a traumatic decision!! . But I will make contact if (when?) my emotional fortitude gets stronger!!

Don

[The_Hawk]

Thanks for all that. I figured you meant it was faster to read stuff but I didn't really expect quite that much faster!

That would make the decision to buy one over the other that much harder (given the limits of the WiFi version)... but speed is very nice.

[DV52]

I use my cable fairly regularly and really can't complain about speed. If you had a workshop and can't wait the 5mins for an autoscan to finish maybe it's worth the upgrade?
But wireless has it's own issues and in my experience with bt vaspc interfaces (and more generally with other rf radios) there's no substitute for an actual cable when it comes to data transfer.
However I've not ever seen the new product so can't give any direct advice other than to as always applaud rosstech for continuing to invest in their product and support their users worldwide 

kamold: I'm getting very nervous responding to another moderator (only kidding)!!

I must agree with the underlying sentiment in your reply - which is (I guess) that value is in the eye of the purchaser!

HEX-NET cables are not inexpensive (even the limited VIN version is expensive). Whether the cost is worth the purchase is ultimately a personal decision about "value". The decision to buy is made more stark if the potential buyer already has a perfectly good cable!

In my case, a unique set of circumstances arose which resulted in a value proposition that was impossible to ignore! Best decision that I have ever made - to get my HEX-NET!

Fair point about adaptation channel Maps Don.
Not owning an mqb platform vehicle my controllers have far fewer channels.
