If you are looking for the best OBD adapter, then first you need to answer the question: "WHY"
if you just indulge in viewing data from the Engine, AT, Climat, etc, then it is better find a quality Elm327.
but, if you want to configure the hidden functions, which are a very lot in PHEV, and make full use of the capabilities of the official MUT-III SE program, then the best adapter is Openport2, (also china clone from AliExpress, or E-bay).
through the MUT-config
from the site of the etacsdecoder
you can also pair the keys, and more .. beacose etacsdecoder itself is not made for this.
