The Datalogger will be also protected with CNG and Vista or later?
Will that logger be tied to VAG specific MWB or also for common OBD values?
Datalogger won't support XP until I can replace CNG with something else. Probably will do this after the first quick/dirty release of the datalogger.
Datalogger will be based on logging RAM variables the same way ECUx worked. Later versions will support logging PIDs, but the B5 S4 ECU doesn't have any PIDs defined internally, so it won't be any use for that car.
