For those that are using their VAG com cable with laptop to log and/or pull LV, there is a fellow forum member who came up with a great app that run on android devices. The refresh rate is as fast as romraider IMO. You can view live parameters, log them, pull LVs at any time, customize the screen with gauges, etc... Check it out. He just began selling it, and trying to see if there is enough interest to continue improving his product. At the moment, it only works with 05-06 models though, but he is trying to see if he can make it work for newer models as well.
