An internal combustion engine fuel system applies injection control pressure (ICP) to fuel injectors (26) to force fuel into combustion chambers (28). A processor of a control system (22) develops data values for injection control pressure set-point (ICPC_T13) representing desired injection control pressure (ICPC_DES) and evaluates the injection control pressure set-point (ICPC_T13) data values for compliance with an allowable dynamic range (ICPC_SP) defined by a data value for a minimum dynamic limit correlated with engine speed (N) from a function generator (132) and a data value for a maximum dynamic limit correlated with engine temperature (EOT) from a function generator (130). …
