Abstract
An engine control system for preventing automatic increasing of an engine speed above a threshold engine speed when increasing engine speed toward an elevated transmission mainshaft speed during a transmission downshift includes a downshift sensor for detecting a transmission downshift in a manual transmission and an electronic control unit (ECU) operatively connected to the downshift sensor for receiving a downshift signal therefrom indicative of the transmission downshift. The ECU automatically increases the engine speed toward a transmission mainshaft speed when the downshift sensor detects a transmission downshift. The ECU limits the increasing of the engine speed to an engine target speed that is below the threshold engine speed.
