Maximum engine torque
WARNING: This page is about a different car, the 2003 Saab 9-3 and 2002 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.
The engine torque curve is stored in the control module memory. It specifies the maximum engine torque at various engine speeds.
The torque is directly proportional to the air mass/combustion at a certain speed.
The unit in the engine torque curve, N.m, is converted to mg air/combustion.
The value taken from the curve is the maximum air mass/combustion value the engine variant allows.
