Hi Tre,
I am not sure what you are asking(signed/unsigned doesn't bother me, but there are variants). Can you provide an example of an area this is used? I don't have a lot of experience with the t43 or t87 so I am learning as well. Since these are "torque" as well as other inputs, it does get confusing to me.
Thanks

p.s. from memory an unsigned is an odd decimal and signed is even(like a supposed checksum or intel type checksum) It's been a while since I did any of this older stuff I like it
