A/T Temp Oil
(A*459/255+B*1.6/255)-40 or (A*(9/5)+B*0.0062745)-40
by your values 6400 and 67C0

I would have expected a two byte temperature
equation to look something like…

(((A*256)+B)*(459/65535))-40 for °F
(((A*256)+B)*(255/65535))-40 for °C

Your equation would exceed 459 if both
bytes are 255?

Just curious how these were calculated.

Thanks Cintakc. I’m always trying to
increase my understanding on how
all this works.

So I should use the equation
(A*459/255+B*1.6/255)-40
?

Where does the B value come from if the PID does not output a B value?

PID does not output a B value – because you had a formula only “A”
(A*459/255+B*1.6/255)-40

221628
62162867C0
A = 67
B = C0

Numbers still seem normal. Only 1 degree F higher than before based on the new equation.

Do you think this is done now? Can I pay you some money for your work and time, if so? There have been a lot of people wanting this feature since this truck came out in late 2015. thank you

May I donate some cash to you for your time? I have some friends that also may donate when I tell them about this. We have been waiting a long time!
