Standalone controllers for DSG/ S Tronic boxes

[Psycho Warren]

Looking for a DSG transaxle solution for a kit car project but wondering if there are any aftermarket "controllers" or ECU's to manage the modern DSG transmissions. An engine ECU that can also do the box would be fine too (and probably easier to wire).

Also are the modern quattro DSG boxes able to be converted to "FWD" only (or rwd in a transaxle set up). Google mentions welding up centre diffs works but that sounds like a bodge.
