Directly after starting the engine, the correction factor is just over 1 and subsequently drops to 1.00. How far above 1 the correction factor reaches and how long it takes to return to 1.00 depends on the engine coolant temperature. This function is called the choke on cars with carburetor engines. Closed loop starting conditions are such that fuel enrichment after starting has just dropped to 1.00 when closed loop starts.
