Abstract
A portable computer based motor vehicle performance monitoring system which performs vehicle characteristic measurements and calculations. The system uses a distance sensor means, a fuel volume flow sensor means, and a fuel temperature sensor means for sensing various vehicle performance characteristics. The system has a computer controlled start/stop feature. It also has a user-prompting programming feature. It also has a combined liquid fuel volume and mass meter which uses a mathematical algorithm which converts volume data to mass data using a temperature sensitive function.
