Hey guys! I've come to the forum a ton for help on other issues but this time I have a weird one, I purchased a OBD2 HUD from amazon (Konwei KW206) and its not reading my RPM or Vehicle speed, i can check the codes and see battery voltage but everything else just kinda reports once and then stops sending info. I'm sure you guys have some sort of explanation for me. thanks!

 

Have you tried any other OBD scanners or apps so far?

 

I had one from AutoZone, some cheap one that worked fairly well but would report super slow I cant remember what it was called though.
