(57) An engine setting system includes: an engine control device (1) and a terminal device
(2), the engine control device (1) including: a first storage medium (1a) that stores
a basic control map and a correction control map, the correction control map correcting
the basic control map; a second storage medium (1b) that temporarily stores data;
and a control section (1c) that performs an engine control based on the basic control
map and the correction control map which are stored in the first storage medium (1a)
during normal driving, the terminal device (2) being connected to and capable of communicating
with the engine control device (1) and defining the correction control map based on
input information, the control section (1c) writing the correction control map as
a provisional correction control map in the second storage medium (1b) at the time
of engine setting, the correction control map being transmitted from the terminal
device (2), the control section (1c) performing the engine control based on the basic
control map stored in the first storage medium (1a) and the provisional correction
control map stored in the second storage medium (1b), and the control section (1c)
rewriting the provisional correction control map as a new correction control map in
the first storage medium (1a) when the control section (1c) receives from the terminal
