PROBLEM TO BE SOLVED: To provide an injection amount control system, capable of improving the precision of the fuel injection amount without erroneously deciding a pulse crack, even if an increase command of the main injection amount is issued, and a data correcting system for correcting the data when the data required for finding AACT by a pulse crack is corrected. SOLUTION: A pulse crack is generates in pilot spill is to be generated after a prescribed time from a pilot spill valve opening time t2. That is, a pulse crack is generated between (H-I) a pulse signal H to be output after a pulse signal G as a calculation reference of the pilot spill valve opening time t2 and a pulse signal I to be output after it. In an ECU, etpls3 stored as a time internal between H and I in a memory is taken as a deciding value, and the presence or absence of the pulse crack is decided by comparing the time interval between two continuous pulses to be output according to the mean revolution of an engine with etpls3.
