Note: Advanced coding (e.g., adding cruise control, key programming) is not its primary strength – it's more a "pro-level scanner" than a "dealer-level coder".
The C4b hardware communicates via HS-CAN, MS-CAN, and SW-CAN at full protocol speeds. High quality units achieve ping times under 10ms. Cheap clones lag, causing timeouts during long coding procedures. Delphi Autocom 2021.11 C4b High Quality
High-quality units support the "Flight Recorder" feature. This allows the VCI to record data in real-time while driving the vehicle. You can set triggers for specific parameters, making it easier to diagnose intermittent faults that won't show up when the car is standing still in the bay. Note: Advanced coding (e
