Hi .
I was wondering if tell me your device is capable of extracting ALL data from ECU . In my project it is important to use data from ALL sensors . As mentioned in( https://en.wikipedia.org/wiki/OBD-II_PIDs ) or atleast Service01.

Yah, you can request data from each PID. You just need to list all ALL the PID's you want.

If you are looking for supported PID's, you can first request all supported PID's then loop each of those. Ex. PID 00 will return which out of 01-20 that are supported.

and it is possible just by changing an arduino code???

yah, you just modify the code and upload it to the device. Check out the github repo, its all available https://github.com/stanleyhuangyc/Freematics
