Reply to Mapping for VCI-100 SE, Two deck version?

Is there any version of the vci-100 se tsi (using traktor pro 1.2) that only utilises 2 decks instead of 4?

I only mix two decks so really have no need for the other functionality of 4 decks, however the general layout of the official DTT mapping is nice so anything similar would be epic.

Also whenever I load the current DTT mapping into traktor my tempo faders only alllow about 2 bpm to be changed, why is this?

Thanks in advance.
