0day usually means it was unknown until he did it. So he used a way that no other chiptuner-hardwareguy did before.
but maybe it is the same way the kessv2 and other good tools read it. he is not interested and has not a inside view in the chiptuning world.
otherwise he would have used a ori from some forum.
so maybe his way was brand new or he only thought he was the one who discovered this.
just ask him
