Abstract
A secondary controller for controlling the performance of a vehicle is described. The secondary controller sends control commands to a vehicle controller while the vehicle is being driven to effect the operation of the vehicle's power train without requiring any modification of the vehicle controller and without falsifying any information sent to the vehicle controller. In some embodiments, the secondary controller communicates with the vehicle controller via the vehicle's diagnostic port, such as an OBD-II port. In one aspect, the secondary controller is used to direct the vehicle controller not to utilize a start/stop feature to automatically turn off the engine in the selected circumstances during normal operation of the vehicle. As such, the control command causes the vehicle controller to operate the vehicle in the selected operating mode in manner dictated by the engine controller.
