    Great doc on how to data log using Vag-Com

    I found this document while researching data logging in Vag-Com and thought some of you might find it handy

    Good find have a gold star!! I was after that sort of info. As I started to do mine:

    Log Blocks 015 & 016 - To check for bad coils
    Log Block 115 - To see the specified Vs actual boost.
    Log Block 002 - To show air mass from the sensor
    Log Block 032 - To check for a O2 sensor/Throttle Valve (+ =lean & - = rich)
    Log Block 031 - To show lamda reading from O2 Sensor
    Log Block 011 - To log boost pressure (In Excel graph actual/requested boost -vs- rpm )
    In a high gear (4th/5th) give full throttle from 1500-2000 rpm to 3500-4000 rpm

    But you just saved me from trawling all over the place!

    so how exactly would you do this boost check, look at blocks 011 and boot the car at the stated rev range, then stop and produce the graph? or does vag com log a certain test time range....can you explain what you have done step by step to get the actual boost vs the requested boost

    The doc I posted shows you how to do everything matey, including producing the graph in Excel. If you don't have Excel then you can download the OpenOffice suite (http://www.openoffice.org/ - It's free and does everything MS Office does!) and use the Calc application which is their equivalent of Excel.

    Block 115 is the one which logs RPM, Requested (Command) boost and Actual boost. You click Start, do your run (3rd gear, 2k RPM to redline) then click stop. That dumps the data into a CSV file which you open with Excel and use to create a graph.

    I've got version 409-1 shareware running fine on Vista. To run the software properly you have to right-click on the Vag-Com icon and choose the "Run as Administrator" option. I had problems with Vag-Com locking up if I didn't do that.

    Vag.com is $99 and at the present exchange rate 50. Seriously though invest it in then you can measure to your hearts content plus it is a invaluable tool. TBH it's the best 50 I've spent on my S3.

    Don't you also have to purchase a new interface with the latest version of Vag-Com though? I thought the 10 cables off eBay (which most of us have got) only worked with version 409-1 and older?

    I've got a USB Gendan cable with 409.1 on XP Pro. When buying it I had to give them the serial number of the trial copy which they then converted to a full version. But yes I would agree that to run the new version you would require one of their specific cables.
