Title: VCDS sample rates
Post by: j2mc on June 08, 2011, 08:38:44 AM
I've followed ross-tech's suggestions to increase sample rate speed, but I am still only getting about 3 samples/sec when logging only one block.  I tried out their acceleration measurement and my 0-60 has a tolerance of +- 0.68 seconds(which seems ridiculous to me).  Anyway is this normal for vcds? 

FYI - I have a 2000 a6 2.7t using the KII usb interface.

You can´t increase the sample rate on your car.
VCSD manages on one block 3samples/sec. , two blockes 2 samples/sec, 3 blocks 1sample/sec.
No further increases possible.....  :-\
The acceleration measurement is a nice feature but if you wan´t "bulletproof" measurements you have to use a gps based device like racelogic powerbox or similar.
If you´re not crazy about the last tenth of seconds VCDS offers a good tool to compare different maps if you use the same test road and car and to have a quick look if the remap is better or worse than before.
