X Tau Enable Manifold Absolute Pressure Derivative Threshold Hysteresis

The rate of change in manifold absolute pressure (in kPa/s) must be below X Tau Enable Manifold Absolute Pressure Threshold minus this value in order to disable X-Tau Direct (transient fuel correction).

Larger values help to avoid repeatedly enabling and disabling X-Tau Direct when the rate of change hovers near the threshold.
