Glancing through the archives, I only see a few references to VAG 1551
emulators (such as the VAG-COM software/cable package).

Since I have one Vanagon with a Tiico conversion, I'm pondering the
choices. The only problem I have the VAG-COM software is...I'm a Mac
person.

Hence, I'm considering one of the alternative packages (such as the one
that works with the PalmOS.) Anybody used OBDScan yet? I noted that it
is one of the "recommended" ones on the Tiico web site.
