BMW F&G Series Gearbox Tuning

Tuning your BMW F&G Series Gearbox can be chosen either on its own or as an option to complement our other tuning services to enhance your driving experience and enjoyment.

With more manufacturers using one or two basic automatic gearbox designs and differentiating them by the way they’re mapped, you’re not always getting the best combination of gearbox and engine power. Our bespoke service will help you make the most of your car’s engine performance and possibly improve fuel economy.


Our BMW F&G Series gearbox software truly transforms the drive and we are able to offer:

- Increased Torque Limiters
- Faster Shift times
- Sport Display Calibration
- Gear specific Torque limiters for faster launches

- OBD connection
- OBD Software upgrade
- Back to stock (Original Software)
