Ok wanted to be able to data log my fuel pressure to make sure its keeping the pressure correct, and also put a safety feature if I every drop pressure.
So the sending unit I have the scale is linear..
.5v = 0psi
2.5v = 75psi
4.5v = 150psi
So my question is because the sending unit is .5v - 4.5v and in the general sensor inputs in tuner studio the range for me to put in the value is for 0v and 5v. So I just calculated that the sending unit is showing 37.5psi per volt or 18.75 per .5v
So do I put a -18.75 in the 0v field? And 168.8 in the 5v field? (the 5v rounds 168.75 up to 168.8 while the 0v stays at -18.75 and doesn't round up)
Does my math seem correct and can I use a neg number in the 0v field?
