Both OBDSTAR P50 Airbag Reset Tool and DC706 ECU Tool can read and backup ECU data. All data will be stored in the Data Management of the device. If you need the data file on your computer, use a USB flash drive to help you import or export files to a PC.
Here is the instruction:
Turn on the OBDSTAR tablet
Go to Home menu, press DP icon
Tap Data Management>> My Data>> Local Data
Find the data file you desire, and long press the file name and the file will be ticked
If you want to copy multiple files at a time, click the boxes at the front of the documents.
Click “Copy” at the bottom
After copying, go to USB Disk, tap “Paste” at the bottom
When it shows the paste is successful, wait about 10 seconds, then you can remove the USB flash drive.
