In an engine system of a machine having a multi fuel engine system, the occurrence of transient events such as gear shifts, grade changes and machine speed changes may be anticipated, and a fuel substitution strategy may be adjusted if necessary to optimize performance during the transient events. Transient events at a worksite may be anticipated and mapped by evaluating shift control logic strategies and worksite maps with truck route, speed and topographical information and determining where the fuel substitution strategy cannot meet the power requirements for the transient event. When it is determined that the machine is approaching an anticipated transient event, an appropriate fuel substitution adjustment can be executed to ensure the engine has sufficient power for the transient event.
