Iff that data is correct then that can be done.

First convert the kPa to inHg by multiplying it by 0.2953

11 kPa= 3.4283 inHg,  307 kPa= 90.657 inHg

Ford uses MAP = Volts * Slope - Offset.

so 90.657 = 4.75 * Slope - Offset (1)

and 3.483 = 0.25 * Slope - Offset (2)

Subtract equation (2) from equation (1)

87.174 = 4.5 Slope

19.372 = Slope.

Substituting back gives

90.657 = 4.75 * 19.372 - Offset

-1.36 = Offset, => Offset = 1.36
