8Y RS3 TCU SOFTWARE FEATURES
End-User Programmable with UniCONNECT+
Reflash your TCU from the comfort of your own home or garage. Within minutes (approximately 70-seconds to be exact on this platform), you'll be enjoying an entirely transformed driving experience.
Optimized D & Sport Modes
D-mode is optimized for improved performance while avoiding the tendency to target quick upshifts to higher gears. S-mode is optimized for faster acceleration in spirited driving.
Quicker Gear Shifts
Unitronic's TCU Performance Software calibration enhances the gear shift speeds making them up to 70% quicker.
Reduced Clutch Slippage
Unitronic’s TCU re-defines clutch engagement strategies to reduce excessive clutch slip in virtually all driving conditions. Users will notice the biggest improvements under light throttle driving conditions, but a more direct experience while driving full throttle as well.
Sailing Mode Disabled (EU/RoW only)
Disabling Sailing Mode keeps the drivetrain fully engaged instead of engaging virtual neutral and free-wheeling when coasting in certain drive modes at speeds between 55kph/35mph and 160kph/99mph. This provides the driver with a more engaged performance orientated feeling and driving experience. Sailing mode is inactive on most North American vehicles from the manufacturer.
