Data presented is always based on the credibility of the person sharing it. Whatever data he comes up with he will ensure is bad. And he won't be able to use his logging tools with the JB4 attached to the OBDII port. But more to the point in my eyes and in the eyes of many in this community, whatever credibility he may have once had, he's frittered away in the last few days with his half coherent and misleading anti-JB4 rants. While his posts often embarrass himself, and lower the IQ of those of us forced to reply, the real victims here are his two customers duped in to liking his posts, no doubt so their technical support from him will continue.
