It's surprising nobody has done this yet, as it would be very popular.
Someone did say Adrenaline tuning had a controller...but have never found any truth in this or units to use. Also found a few threads from a while back where people said they were working on it...but they never came to anything.
others have done it other DCT boxes...but none the VW DSG...odd, given it's probably the most common application.
