I don't have that function,apparently. I can only read
the inches in HG's with my laptop scan tool. If you
need the actual barometric pressure for my area,I can
find that out.
By the way,what scanner can I get that will let me
read enhanced codes (including the barometer reading
you're talking about) and transmission data,etc.?
Anything around $400-500 or less that will let me do
that?
Thanks!
