1. A system for controlling fueling of a vehicle engine coupled to a transmission system during launch of the vehicle, comprising:
- a control unit selectively coupled to a throttle sensor of said engine, wherein said control unit is configured to obtain an estimated weight of said vehicle and receive inputs from said throttle sensor and said engine to detect a high throttle demand to reach a high target engine speed during launch of said vehicle;
wherein said control unit is configured to, upon detecting said high throttle demand, adjust a default high throttle ramp rate associated with engine speed based upon said estimated weight of said vehicle.

Abstract
A system and method for controlling a throttle ramp rate of a vehicle. According to an embodiment of the invention, the controlling of a throttle ramp rate of a vehicle is accomplished by determining the target engine speed for a vehicle during a vehicle launch. If it is determined that there is a high throttle demand upon the engine of the vehicle, a throttle ramp rate offset amount is determined, which is based upon an estimated weight of the vehicle. A default high throttle ramp rate may then be adjusted based upon the determined throttle ramp rate offset.
