Matched calibration
Engine and transmission torque requests are reviewed together so the two control units work as one package.
Gearbox tuning for your BMW 5 Series
Gearbox software should complement the engine calibration, torque curve and transmission fitted to this exact E39 powertrain.
Shift strategy
Where supported, shift timing, response and manual-mode behaviour can be refined for the way the vehicle is used.
Torque management
Transmission limits are handled carefully around the real engine output instead of being raised without supporting data.
Before you book
We will confirm the gearbox type, software support and mechanical condition before recommending a calibration.
