The ECU Measurement and Calibration Toolkit is a software add-on for the LabVIEW, LabWindows™/CVI, and Microsoft C/C++ programming environments. The software provides high-level, easy-to-use functions based on the Universal Measurement and Calibration Protocol (XCP) and CAN Calibration Protocol (CCP). These protocols enable help you read and write to internal ECU variables and characteristics as defined in ASAM (.A2L) database files. By using these database files, the toolkit automatically applies all scaling information and returns data in engineering units for easy analysis, presentation, and logging. In addition, the toolkit offers examples for common applications such as measuring ECU variables or manipulating ECU characteristics using 1D to 3D user interfaces.
