there are now THREE boxes for the TT's
part of the changes seem to be for the immobilzer feature on the TT the other seem to be emmisions and OBDII.
I Don't know anything for sure.
I would bet that the H box is less "Chip-friendly" and more likely to over-ride power requests in the search for cleaner exhaust
also each type of Ecu sub-versions on the box
like 0002 or 0003....
not sure what changes are taking place there
