Development of ECU calibration system for electronic controlled engine based on LabVIEW

Based on LabVIEW software platform, an ECU calibration system was developed. The communication protocol is Keyword Protocol 2000, which is the universal serial communication Protocol in international automobile industry. This system has vivid and intuitive interface that can realize real-time displaying of monitoring datas of ECU. It also has off-line and on-line calibration function, calibration datas and monitoring datas can be saved conveniently. The experimental results proved that the system was stable and reliable, and had good real-time performance and strong expansibility.
