What’s new
Version 4.20 · Updated October 10, 2025
Dear Users, The software has been updated. We have fixed issues, optimized user experience, and added new features. Here’s a plain-language breakdown: I. Issue Fixes a. Fixed VCI connection failure: The strict restrictions on Mode 81 in the original CAN branch of the protocol stack caused incorrect command sending to the lower-level device; this has now been resolved. b. Fixed data stream issues: Resolved crashes of the data stream executor, failure to recognize random sequence numbers, and protocol stack errors when receiving large data. c. Fixed text display: Multi-line input is automatically converted to single-line display to avoid confusion. d. Fixed system jump/CDB recognition: Eliminated the "parent system undefined" prompt during system jumps and resolved unknown errors when recognizing CDB files without menus. e. Fixed update and download issues: Successful updates of lower-level device firmware/config tables and successful downloads of Chinese-version CDB packages are now ensured. II. User Experience Optimization a. Optimized metric-imperial unit conversion: Removed redundant rules for faster and more accurate conversion. b. Updated startup interface: Now cleaner and more intuitive. c. Overseas version optimization: Added "Condition Mode" – automatic metric-imperial conversion is performed before numerical comparison. III. New Features Added a. New data stream functions: Added display of maximum/minimum values; a "function not supported" prompt is shown when the number of data stream entries is empty. b. New capabilities: Added the CDBD5XX algorithm; added "Condition Mode" to the overseas version. We recommend updating to the latest version as soon as possible. For any issues, please contact [Customer Service].
