This is a full conversion of the factory M3 GTS transmission software to work on N54 & N55 equipped vehicles. The conversion takes into consideration the torque characteristics and rev limits of the N54/N55 engine but retains the lightning fast shifts and smooth driving experience that the M3 GTS tune is famous for.
 
This product is a demonstration of the full GTS conversion. It offers the full functionality but is limited to 5800 RPM. The transmission will automatically shift up at 5800 RPM in all modes.
