Load compensation: A/C

When DICE sends bus information A/C ON, Trionic T7 calculates the impending torque requirement of the compressor using the A/C pressure. The value is converted to mg air/combustion and constitutes the air mass/combustion required to compensate for the torque requirement of the compressor.
