A vehicle control system is disclosed for modifying vehicle operation and includes an engine control unit having at least one processor. A vehicle network is provided as well as a first handheld wireless device having a GPS module, a local wireless communication module, and a distance wireless communication module. A gauge has a wireless communication module operable to communicate with the first handheld wireless device and at least one display for communicating information to a user regarding vehicle operating parameters. Memory accessible by the processor and memory having software stored thereon are provided, the software being configured for execution by the processor and including instructions for providing a boundary map within which the vehicle may operate under normal operating conditions. The vehicle is placed in a degraded operating mode if the vehicle moves outside of the boundary.

Device and method for supervising and modifying vehicle operation

A recreational vehicle includes a seatbelt sensor configured to detect when a seatbelt is in an engaged position or a disengaged position and an engine control module in communication with the seatbelt sensor to automatically limit a maximum speed of the vehicle to a reduced maximum speed limit upon detection of the seatbelt is in the disengaged position.

Adjustable performance for a vehicle

A diagnostic system of a vehicle for diagnosing a drive belt of a continuously variable transmission. A diagnostic circuit detects or predicts a fault of the drive belt based on an operating parameter received from a sensor associated with the vehicle during a predetermined diagnostic period.

Diagnostic systems and methods of a continuously variable transmission

Electronic throttle control

A continuously variable transmission (CVT) is provided for use on a recreational or utility vehicle. The CVT is electronically controlled by at least one control unit of the vehicle. The CVT includes a primary clutch having a first sheave and a second sheave moveable relative to the first sheave. An actuator controls movement of the second sheave.

Primary clutch electronic CVT

An electronic throttle control (ETC) system is disclosed for use on a recreational or a utility vehicle. The ETC system includes a drive mode selection device for selecting between a plurality of drive modes. The ETC system provides an adjustable engine idle speed and an engine power limiting feature.
