The Flex TCU SW Package allow full read and full write of the TCU, including each of the memories stored inside the transmission control unit without any encryption. It just doesn’t require to open the control unit, while allowing exactly the same functions as a regular boot mode. Tuning, align, bypassing security and restoring backup are no issue at all. The different is the fact that files are non encrypted and that the speed has been generally been improved.

Furthermore, you do not need to make any ignition switch, as Flexbox will take care of it. Reading times have been tested from 2 to 3 minutes in total, depending on ECU model. Writing times depend on actual size of modification inside file, from few seconds to about 9 minutes.
