Please note the alternate equations
suggested in my earlier posts… still waiting
for someone to try the 2A Dpid also
mentioned previously.

Glad you got it working with the better adapter.
I am curious what header is being used with
Auto.

Well, 1000/15625 = 0.064 and 1/16 = 0.0625 so I doubt I’ll see much difference from 0.063. It looks like either one of your alternate equations is more accurate than using 0.024 in my case.
How would I tell which header is being used with auto?

Go into the pid editor while connected
with vehicle running and “Test” for hex
response from vehicle.

ATH1 elm command turns display of header
ON while ATH0 turns it OFF.

Adding command to the diagnostics start
command field should work temporarily.
There is also a send OBD command
pushbutton that could be used as well.

^^^^
Not sure I did what you wanted. I get a response of 7F22130112
when I test.
I did try 6C10F1 in the header instead of Auto and it works if that helps.

What is the 2A Dpid?

The interesting reading links
above point to threads
which discuss the full 2A… dpid
address used. It may actually work
for you and vehicles that use a
different pid than 221301 as well.

Based upon previous posts with Cintakc
I believe Torque variable addressing
may be off by a byte for A… and Nx type
addressing for 6A responses to 2A
requests.

I was wondering if the 6C10F1 worked. Thank
you for the update.
