Stage 1 Road Tuning 

The Stage 1 Tune is made for the sporty, yet economy aware driver. The setup makes use of the massive low-end torque of the 3.0 Litre Turbo engine and let's you cruise around well below 2000 rpm in D mode. A switch to S/M mode transforms the transmission and gives you shorter shift times + rev-matching downshifts without sacrificing comfort. Torque limiters are raised to 600 Nm (442 ft.lb) in every gear to accomodate the potential of tuned engines. This setup is based on the well known Alpina configuration.

Stage 2 Sport Tuning 

The Stage 2 Tune is made for people wanting the most from their transmission on street use. The revised Torque Converter setup provides snap-on take-off feeling at every junction, the cut-shift times in D/S/M modes wash away the sluggish shift feeling, BMW has implemented in these transmissions. The Sport Setup is also the Map of choice for people with tuned engines. The raised TQ Limiters allow up to 700 Nm (516 ft.lb.) of Torque in every gear.

Stage 3 Sport+/Track Tuning

The Stage 3 tune raises the bar in every aspect. In D mode only slightly firmer to the Stage 2 tune, a switch to S or M mode transforms your transmission. Shift times are cut to a minimum and sacrifice shift comfort in favor of pure speed. On downshifts you will experience instant and very audible rev-matching. The Race cal offers a true Manual mode for the first time in non BMW - M vehicles. Instead of forced upshift, you will hit the engine rev-limiter like in a manual car. Torque Limiters are upped to 1000 Nm (737 ft.lb) , to leave room for advanced engine tuning. Line Pressures have been increased where necessary, to lift the maximum TQ capacity of the 6HP21. If you drift your vehicle, visit race tracks, or just love being in control, this is the map of choice.
