Ross-Tech is now testing a simple utility to help get Auto-Scan and channel maps posted. While I came up with this concept, the heavy lifting has been done by Sage so he get 98% of the credit here.
What does Alligator do? VCDS has a function to go into each control module and capture a snapshot of all the live data (channel map). The process generates a file or two for each module and posting all of that data online is a very time consuming task. Alligator bundles up all the files, puts them in order and formats them so all you need to do is copy/paste the results into a forum post.
Why would I want to post maps online? The short answer, to help others. A common question that comes up is "What should the value be for blah blah blah?" There is so much data in these cars over the last +20 years, no one knows what normal or good data is for everything. So by posting maps from known good cars, everyone will have access to this kind of information.
How do I get this Alligator? Alligator is bundled with Seb's Label File updater. Here is the download link:
Once the Updater is complete, you will now have 2 new files where VCDS is installed:
- CM Alligator 0.8.2.exe
- Engine at idle and up to operating temperature.
- Full charge on your laptop, or have it plugged to the wall.
- If possible, no fault codes in the modules.
Select "Whole Vehicle (CAN Only)". Pick which function, Measuring values and/or Adaptions. Measuring values are preferred over Adaptations. Have the Output set to Pre-label file. Then click on [Go] to start the processes. VCDS will create and save an Auto-Scan file with this process.
K-Line Diagnostics: Start VCDS, click on [Options] and then set the "Debug Level" to a value of 2.
Now click [Apply]. Now run an Auto-Scan and VCDS will run Measuring Block and Adaptation maps of all control modules. This took about 40 minutes on my 2004 Jetta. If you do this on a 2005 Touareg, set up camp for the night, you gonna be there a while.
Note - Alligator needs to see the VIN through the diagnostic port. This started with vehicles in 2002. 2001 and older cars Alligator will most likely not work.
I've made maps, what do I do to share them? From the first screen of VCDS, click on the tiny white VCDS icon in the upper left corner:
From the drop down menu, select "Open VCDS folder":
Once the VCDS folder opens up, double click on the CMAlligator.exe file to start Alligator:
Click on the [Browse] to open the location where Auto-Scans are saved. Note that files names breaks down as follows:
Click [OK] and now you can start a new thread in the Reference Scans and Maps of Non-Broken Cars section. Please title your forum post as follows:
- (Year) (Model), (Engine Type) (Engine Code)
If you did both maps of both Measuring Values AND Adaptations, please post the Measuring Values first. Then in Alligator, select "Adaptations", then [Copy], now reply to your own thread and paste in the wall of text that is Adaptation.
Too much data from the maps? There is a line limit on how much text you can put into a single post. In cases where there is too much data to be copy and pasted, Alligator will break things down into smaller chunks that can be posted. If this happens, you will get this kind of message after you click on [Copy]:
Alligator will now have a number drop down list next to the [Copy] button:
The first section has already been copied, you can paste it and post it in your thread. Then from the drop down menu, select the next number and [Copy] and paste that section of data as a reply to your own thread.
I've replied to this thread showing an example of what the end results look like.
For cars that have UDS type control modules installed, only our current generation of interfaces, the HEX-NET and HEX-V2, can make channel maps on those. If you are using an older generation interface, it is not possible to make channel maps on UDS modules.
