If the software drops connection mid-scan, it is usually caused by a poor-quality dual-board hardware clone struggling with firmware speeds. Lower the baud rate in your Windows COM Port settings, or upgrade to a high-quality single-board hardware unit. Conclusion
The performance of the 2021.11 C4B release is significantly higher when paired with high-quality Single-Board (Green PCB) VCIs featuring genuine 9241A chips and 5V relays. Low-end dual-board variants may throw "VCI Not Found" or connection dropouts during high-speed CAN operations (e.g., Ford or BMW scans). Minimum PC Requirements
The release is widely considered one of the "golden" builds for the C4 platform. However, many users run into issues not because of the software, but because of the setup.
