on how to safely flash this firmware onto your specific diagnostic tool? Delphi DS150E Firmware Upgrade Procedure
Determine if your Delphi tool is a high-quality "Single PCB" (green board with 9241A chips) or a "Dual PCB." Firmware 3201 works exceptionally well on high-quality single-PCB devices.

Updating to version 3201 prevents connection drops during live data streaming.It fixes bugs found in older firmware iterations like 1622 or 2100.Mechanics rely on this release to unlock faster data transmission speeds over Bluetooth and USB. Benefits of Upgrading to 3201
By carefully following the instructions above, you can successfully locate, download, and install the correct firmware, getting your diagnostic tool back to full functionality.
Delphi firmware 3201 is the internal software embedded onto the microprocessor of single-board and dual-board DS150E diagnostic clones. It acts as the translator between your vehicle’s OBD2 port and the diagnostic software running on your computer (such as Autocom or Delphi 2020.23, 2021.11, and newer releases).
: Specifically optimized for high-quality Single Board VCI units. Delphi Technologies had released Firmware 3201 for their
To manually apply the 3201 firmware files to your diagnostic software installation:
In the top menu, click on and select Hardware Setup .
Delphi firmware 3201 is the internal software that runs on the microcontrollers of DS150E, Autocom, and Multidiag clone or original multiplexer hardware. This specific firmware version acts as the translator between your computer’s diagnostic software (like Delphi 2020.23, 2021.11, or newer releases) and the Electronic Control Units (ECUs) inside modern vehicles.
The update is a critical system enhancement for the DS150E and Autocom CDP+ diagnostic interfaces . Specifically optimized for single-board (1-PCB) VCI hardware , this version expands vehicle coverage to include models up to 2021/2022, providing the stability and communication protocols necessary for modern automotive electronics. Why Update to Firmware 3201? Ensure you have legal access (e
Open the existing folder and copy all its contents to a safe backup folder on your desktop. Delete the contents inside the original Firmware folder.
Verify your serial number (usually 100251) matches the firmware version.
Wait for the progress bar to reach 100%. The LEDs on your device will flash rapidly during this time. Do not touch the cable or turn off the ignition.
Open your Delphi software, go to Settings > Hardware Setup , select your COM port, click Test , and then click Update Firmware . Important Safety Tips
