Okay so at least you're not running that damna$$ :)
I need to know as well what can be datalogged with
VAG-COM from a 3B ECU, I know the AANs are more
complete in these regards, offering more values that
can be logged, but maybe someone who has tested it
knows and will let us know... Brett??? I know you're
using it but did you try to do some datalogs with your
Did anyone ever try to make a separate "blackbox" that
logs all the inputs/outputs from the ECU and can
display them graphically? I know the 034 EFI offers
that but my budget isn't set up yet for a programmable
EFI system, plus I'm starting to work on my chips
myself so there's no real need for that, except for
the datalogging feature :)
