'Is this table suitable?'
Fuel pressure analog signal from sensor is calculated with:
Vout=(c1*Pabs+C0)*Us
- 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
Gives the following look-up table:
P kPa Vout devision multiplier
