Delphi Autocom 202111 C4b -

The Delphi / AutoCom 2021.11 "C4B" release is a popular third-party modification of the professional diagnostic software used for vehicle OBDII scanning. This specific version is widely known in automotive forums for being a stable, "activated" release that includes several functional improvements over older 2020 releases. Key Features and Improvements

Expanded Vehicle Database: Includes passenger cars and heavy-duty trucks updated through late 2021, allowing for diagnostics on newer models that previous versions (like 2020.23) could not access.

C4B Revision Fixes: The "C4B" tag often refers to a specific community "crack" or repack (often attributed to creators like Cars4Backup or similar forum contributors) that addresses common bugs such as:

ISS (Intelligent System Scan): Improved stability when scanning all ECUs simultaneously.

Bluetooth Connectivity: Better handshake protocols for DS150E/VCI clones.

History Saving: Fixes for the "Session History" bug where previous scans weren't properly logged.

Generic OBD: Full support for standard EOBD/OBDII protocols for emissions and engine data. Technical Requirements

To run this version smoothly, your hardware should meet the following: OS: Windows 7, 8, 10, or 11 (64-bit is highly recommended).

Hardware Interface: Compatible with DS150E or Autocom VCI (single or double PCB).

Note: Using a high-quality "Single PCB" with the 9241A chip is recommended for full BMW/Ford/VAG compatibility. delphi autocom 202111 c4b

Firmware: Typically requires firmware version 1622 or 3201 depending on your VCI hardware revision. Common Installation Steps Most "C4B" distributions follow this general workflow:

Disable Antivirus: Third-party activators are frequently flagged as "False Positives."

Install Main Files: Run the setup or extract the pre-installed folder to C:\.

Activation: Generate a FileActivation.xml through the software, then use the provided "Keygen" or send the file to the distributor to get the activated version back.

Driver Update: Ensure the VCI is recognized in Windows Device Manager under "Ports (COM & LPT)." Comparison: 2021.11 vs. Older Versions Feature 2021.11 C4B Model Coverage Up to 2020 Up to 2021/22 Speed Optimized (Faster menus) ISS Stability Occasional Crashes System Requirements Requires .NET Framework 4.8+

Caution: As this is modified software, always run it in a Virtual Machine (VM) if you are concerned about system security, and ensure your VCI firmware matches the software version to avoid "bricking" the hardware interface.
