FWIW,

I poked the register # 4923 into the scangauge connected to my HAH and was surprised to see it return a value.

OBDII values should be standard across different product lines but I am confident this usually wont be the case so who knows what this value is the gauge returned to me?

The value on the scanguage was a varying one and these are two of the replies

486bo8410e919b

another one was

486bo8410c0a8496

Now what the heck does all this mean?????????
