1. A system, comprising:
a fuel system configured to supply one or more of a first fuel, a second fuel, and a pre-mixture of the first fuel and the second fuel to at least one cylinder of an engine; and
a controller including instructions stored in non-transitory memory thereof that cause the controller to:
determine an auto-ignition level is less than or equal to a threshold level,
adjust a timing of an injection of the first fuel to retard the timing while maintaining a substitution rate in response to determining the auto-ignition level is less than or equal to the threshold level, and
incrementally reduce the substitution rate in response to auto-ignition occurring following adjusting the timing of the injection of the first fuel.
