A machine may include an engine, a traction device, a continuously variable transmission (CVT) connecting the engine to the traction device, an operator input device outputting engine output command signals input by an operator, an engine speed sensor monitoring an engine output speed, and an electronic control module (ECM). The ECM may control the engine to a target engine speed using engine speed sensor signals as feedback. A desired percentage of peak power of the engine may be determined from the engine output command signals, and the target engine speed may be determined from the desired percentage of the peak power. The ECM determines a CVT transmission ratio that will cause the CVT to apply a load to the engine that will cause the engine to run at the target engine speed.
