I would like to increase quantity of air which going to engine. Unfortunatelly to do that I must use 3Bar sensor,
standard max reading value is 2570mBar.

How to do linearizaton of new sensor?

1.Get a new sensor.
2.Looking at the part number find in which cars it is originally mounted.
3.Find ORI map from one of those cars.
4.Find the linearisation of the new sensor in the ORI map.
5.Find the linearisation of the old sensor in the ORI map from your car.
6.Replace the values from the new sensor it place of the values from the old sensor.
