I'm horrible with math. I never did well in school, BUT if the teachers would have mentioned how much I would use it when tuning, I WOULD have tried MUCH MUCH harder!!!!
Here is the deal. I want to log exhaust back pressure. I will be using my egr circuit. I have the pro version, but I want to save my few remaining inputs... My sensor is I believe a 0-100psi range. these are the voltages I see at these pressures...
0 psi @ .51 volts
5 psi @ .65 volts
10 psi @ .80 volts
15 psi @ .96 volts
20 psi @ 1.12 volts
25 psi @ 1.25 volts
30 psi @ 1.40 volts
If it matters the baro is at 12.79 at the time of these tests...
So my function would look like this...????
([PID.2811]/(?/?)+.51)/[PID.2340.IMP] ????
I'm ok with working this out on my own, but I don't even know where to start. any help would be very much appreciated...
. 11.87 @ 114
