STG1 Road/Comfort Transmission Tune:
The Stage 1 Map lowers the overall RPM level during driving and smoothly engages the torque converter in 1st gear, to reduce consumption. On City Driving this map can save up to 10% of fuel. Shift times have been slighty optimized and D-Mode has been configured to better use the full power band of the M57 engine under full throttle.
Features include:
- Added Gear-Display in D-Mode
- Increased Torque Limiters
- Raised Clutch Pressure for in-put torque
STG2 Sport Transmission Tune:
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. Relaxed Cruising on low loads + proper shifts when flooring it characterise the sport setup.
Features inlcude:
- Added Gear-Display in D-Mode
- Increased Torque Limiters
- Raised Clutch Pressure for in-put torque
STG3 Sport+/Track Transmission Tune:
You won't recognize your good old auto transmission with our Stage 3 file. Shifttimes under WOT have been cut by over 50%, reactions to gear lever inputs in M are instant and trigger really firm, fast shifts. At the same time, the Stage 3 keeps the comfort and smooth shifts during normal driving. All shiftmaps have been recalibrated to create a way more lively driving experience than before. Last but not least we removed the auto-upshift in manual mode, to let you have fun, when you want it.
Features include:

- Increased Torque Limiters
- Raised Clutch Pressure for in-put torque
- Reconfigured Logic, similar to M-Car
