This patent describes an engine data processor system having a real time recall feature, the system comprising: means for measuring operating parameters of an engine in real time; means for converting the measured operating parameters into a data table having separate words, each set of parameters defining an engine profile indicative of the value of the measured parameters; means for updating the data table at an input cyclic rate with new values of the operating parameters; means for communicating with a permanent data recordation device over an output channel; means for outputting words from the data table at an output cycle rate to the communicating means; auxiliary memory means; means for controlling the auxiliary memory means, the controlling means being capable of writing information into the auxiliary memory and reading information from the auxiliary memory; the controlling means being operable in a first mode communicating the words from the data table at the output cycle rate and storing them in the auxiliary memory; the controlling means being operable in a second mode set by a command at a particular time to discontinue storing the words from the data table in the auxiliary memory; the controlling means being operable in a third mode set by a second command at a particular time to transmit the stored words at the output cycle rate to the communicating means.
