Just put a 3Bar MAP sensor in my car (A01G ROM) and altered the scaling at:

<table name="Manifold Pressure Sensor Scaling " storageaddress="1000CC" />

Car wouldn't start with MAP reading at 31-33 kPa in free air.

Turns out the scaling values are actually listed in 3 places in the A01G ROM:

<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" />

Rescaled all of them and the car started up properly with a normalized MAP reading.

I think the last one at 11CC20 was the critical one used.
