In order to speed up the development and application of the electronic control system of small-displacement engine

ensure the calibration of electronic control system and matching the system with it

the monitorting system for small-displacement engine monitoring system on electronic fuel injection is developed.The programming techniques based on VB MSComm controls is designed to collect the dates of engine’s operational parameters;the MSComm controls in the environment of VB 6.0 is used to carry out the correspondence between personal computer and single-chip processor

and achieves the purpose of the engine’s working parameters visualizations

it offers significant support for the optimization of the engine working parameters.
