As you say, this is wikipedia and the important bit is marked 'dubious' and 'citation needed' if you look closely. Needs to be peer reviewed or company site to be a fact.

I totally understand that, but to be honest I don't really know what else you're going to be able to find. The part numbers for the Leon DSG variants match the part numbers on the Golf DSG variants, so we know Seat certainly haven't removed anything, and they are using the same boxes as the rest of the VAG group. You won't find proof of the fact that a DSG is an adaptive transmission other than the way it behaves on the road, and taking their word for it. Manufacturers simply do not publish the details of a cars software for all to see so we can examine it for ourselves. I wish they did, but they don't. Its fairly obvious why, if you think about it. If they did every factory in China would be spewing out knock off copies in days.

People who have taken a look themselves however, have been able to confirm the fact that a DSG ECU isn't intelligent, merely it is programmed to be adaptable. it has a selection of maps available and chooses the best one to suit any given situation based on what is happening right now from sensor data. If it made a bad decision last time and slipped a clutch, it can learn from that to prevent it happening again next time. Much like a laptop is just a pile of parts until you install windows to operate them all, a DSG without its ECU would be entirely non functional. All 'fuzzy logic' means is that the box has software in it that can make decisions. Even a modern washing machine has fuzzy logic. Ever wondered how it knows to slow down the spin cycle if there is an unbalanced load in the drum? Its just software and sensors.

I imagine that if you spoke to someone like Revo, who do DSG remaps, they would probably know more about it than you and I.
