So now that we know more about the BMW/Getrag Dual Clutch Transmission from chapters one and two, we can further learn how to control all the spinning gears and clutch packs. Currently, the best way to do that is with the HTG GCU (Gearbox Control Unit). The GCU is a transmission controller that works in a very similar manner to many of the standalone ECU's on the market. It is as configurable as you can imagine and has no OEM software or safeguards to work-around.
