the actual shift points are determined by the dsg's transmission ecu, which commands a hydro-mechanical unit. the transmission ecu, combined with the hydro-mechanical unit, are collectively called a "mechatronics" unit or module. because the dsg's ecu uses fuzzy logic, the operation of the dsg is said to be "adaptive"; that is, the dsg will "learn" how the user drives the car, and will progressively tailor the shift points accordingly to suit the habits of the driver.
