Abstract
An engine output characteristics control system includes means for monitoring a selection of speed ratios of a power transmission to provide information concerning transmission gear position. The control system receives transmission gear position indicative information to detect selection of a specific speed ratio of the transmission for providing information indicative of the selection of the specific transmission gear position. The control system is responsive to the specific transmission gear position selection indicative information for deriving an engine control signal for controlling the engine output characteristics so that the engine output is adapted to the specific speed ratio.
