The maximum engine torque must be limited while changing gear for reasons of strength. TCM sends continuous bus information indicating the maximum engine torque.

Trionic T7 converts N.m to mg air/combustion. The value constitutes the maximum air mass/combustion permitted by the automatic transmission.
