Idle Active Engine Speed Threshold Multiplier

This table defines a multiplier to the idle active threshold as a function of idle inactive time.

This table can be used to increase the idle active engine speed threshold when the driver is off the throttle, but the engine speed is not dropping below the threshold. The idea is that higher multiplier values will be defined for times when idle has been inactive longer. This makes it more likely that engine speed will fall below the current threshold (and enter idle mode).
