hi. trying to replace factory 2.5i map sensor with a wrx 2.5bar sensor 22627AA170 to read boost. But this ecu has and odd scaler value. 0.019 offset, .012 multiplier. i tried the wrx values but doesnt read right, goes from -11ish to only 1.74 at 15psi. i thought maybe its in Bar but coverting to bar doesnt work either. Any ideas how i can get a 2.5bar sensor to work?

I think the definition may be screwy and that the "map sensor" is actually a barometric sensor
