A vehicle control system includes: a fuel control module configured to control gasoline fueling of an engine in open loop based on a target engine lambda; and a burner control module configured to control gasoline fueling of a burner based on (a) a target lambda input to a three-way catalyst (TWC) in an exhaust system of the engine and (b) a lambda of exhaust input to the TWC. The burner is coupled to the exhaust system between (a) an output of the engine and (b) an input to the TWC.
