An electronic control unit for a steer-by-wire vehicle steering system includes a data storage component that stores a desired lateral acceleration versus steering angle profile with regard to a range of vehicle speeds and a processor operably and electronically coupled with a steering wheel angle sensor and a yaw sensor. The data storage component includes electronic instructions that causes the processor to receive steering wheel angle data over a range of vehicle speeds, receive vehicle yaw data over the range of vehicle speed correlated to the steering wheel angle data, generate an observed lateral acceleration versus steering angle profile with regard to the range of vehicle speeds, and generate a steering ratio correction based on a comparison of the desired lateral acceleration versus steering angle profile and the observed lateral acceleration versus steering angle profile.
