Code:

<table name="Manifold Pressure Sensor Scaling A" storageaddress="1000CC" />
<table name="Manifold Pressure Sensor Scaling B" storageaddress="1000E4" />
<table name="Manifold Pressure Sensor Scaling C" storageaddress="11CC20" />

Scaling C is definitely the MAP sensor.

I can't find where Scaling B is used yet, I can't find references in it to the ROM yet.

Scaling A is another sensor, I don't know which.

The 16 bit value is stored in FFF87CBC, after scaling sits in FFF87C80. I logged this just now engine off and got a steady 0V (=-20 kPa using stock pressure sensor scale and 3kPa if using 3Bar pressure sensor scale). I think it is unlikely this relates to ambient pressure - anyone want to log and see what this one is? These RAM addresses should be the same between A01G and A00C/A01C.
