Abstract: An indicated mean effective pressure (IMEP) module determines IMEPs for combustion cycles of cylinders of an engine, respectively. A coldstart indication module indicates whether the engine is in a cold state after a startup of the engine. A fueling correction module, when the engine is in the cold state, selectively increases a fueling correction for one of the cylinders based on the IMEP of the one of the cylinders. An equivalence ratio (EQR) module selectively increases an EQR of the one of the cylinders based on the fueling correction for the one of the cylinders.
