    Methanol pressure sensor slope configuration help pls

    Guys and gals i have a 5v pressure sensor that should read .5 volts at 0 pressure and at 4.5 volts it should read 150 and 150 is max.... Ive tried to configure it with a little sucess but im getting 18 psi at idle pretty much with the way i had it configured... Any help would be appreciated thanks in advance!

    Try using my little spread sheet. It was meant for wide bands but I use it regularly to calibrate map sensors and fuel pressure/oil pressure sending units.
