Abstract
A CVT controller 22 of a vehicle 10 communicates with the engine management system (EMS) 20. When a manual shift between simulated fixed ratios is performed, the CVT controller 22 sends a shift signal to the EMS 20 which alters the engine torque for the duration of the shift in order to simulate a manual shift to provide, for example, a sporty feel to the vehicle 10.
