Hello people,

most map sensors are linear ,

If you know max vacuum volt value and max pressure volt value ,
than input this values excel "curve fitting" formula ,

excel give us linear formula ,

here is the our PRT06 map sensor`s formula ,
Bar= (0,5111*volt) + 0,0722

for example ,
if the prt06 out is 1.820 volt ,
(this is the sea level value)
Pressure is 1.002 BAR ..

if out is 4.750 volt,
pressure is 2.5 bar

if you understand pic programmer ,
you can make yourself a lcd boost display ..

maybe later, I can make a lcd display program for you ..
