The Difference between these two products is look and update method.
This is pic of master.
This is pic of X431 GX3
1st we check out how look is different see the above pics. So as you can see the only the shape of the red and green switch is difference nothing else.
2nd main difference is update method. At here X431 GX3 wins against X431 Master. GX3 update cost is less and method is very easy to install software just you have to do is to download software provided by us in email and copy and paste in memory card. Where as in X431 Master update method is quite difficult compare to X431 GX3 as you have to download individual software from www.x431.com and then u have to run update using x431 update tool software also its free for one year but cost much more then update of GX3.
Other then all function and work is same as like master like Fault Diagnose, ECU Coding, DataStream, Adaptation, Immobilizer, AirBag, ABS, Instrument & Sensor Waveform, Actuation Test.
