i don't think it's the ELM so much as it is the incredibly large overhead the OBD2 PID request requires...

Mark, what kind of update rate do you see with 24 PIDs? does EFILive display an update...

i believe that's partly why a lot of the ELM327 based applications have PID "priorities". high priority gets updated often, low priority, not so much.

it would seem that the OBD2 communications...

that's...... so odd.

why would they purposely make the OBD2 PID request protocall with more overhead than necessary?

if i had to guess, that would be where i would expect extra commands to be needed.

luckily, one ADX would cover almost all applications, to a certain degree.

i'd rather do that than the ~250+ that i have in progress for the GM OBD1 applications.
