Please help to interpret VCDS log

Post by Shoppinit » Thu Oct 08, 2009 9:23 pm

Hi,

I logged this data from my car, and while I understand it I have nothing to compare it too. Boost seems to be late, but maybe it's normal?

Any comments appreciated.

I think you'll find it is to do with the time stamps but at least the two lines are around the same values.

Thanks, but the graph data is logged on the same measuring block group, so I would have thought that the time was the same for all values.
