Reducing emissions and improving energy efficiency are major drivers of powertrain development. In order to make progress in these areas, optimizing the interaction of the transmission and the engine or e-motor is vital. 

Calibration is about adjusting the parametrized variables in software to match the powertrain to the vehicle. Good calibration improves the driving comfort and quality of the vehicle while also reducing energy consumption. GRCE Tech is experienced in both bench calibration and in-vehicle calibration of automatic transmissions (AT/CVT/DCT/AMT) and Dedicated Hybrid Transmissions (DHT).
