Fuel pressure analog signal from sensor is calculated with:

Vout=(c1*Pabs+C0)*Us

Look-up table for multiplier: \ MembersPage/Fuel?_Pressure

Vout = signal output voltage in V

Vs = supply voltage in V

Pabs = absolute pressure in kPa

C0 = -5/350

C1 = 0.8/350 kPa ^-1

With Vsupply at nominal 5V this means

Vout min = 0.500V = Devision 0

Vout max = 4.500V = Devision 255

With the req_fuel calculated at 255 kPa Fuelpressure the original PW is altered by 1/1 at Vsens_out = 2.843V
