[Td-d]

MAP is defined? FFF88F74, or FFF8DB7C.

Can you send me a log of MRP, so I can see what the issue is?

Have you got it correctly scaled?

<conversion units="psi relative" storagetype="float" expr="x*0.01933677" format="0.00" />
<conversion units="bar relative" storagetype="float" expr="x*0.001333224" format="0.000" />
<conversion units="mmHg relative" storagetype="float" expr="x" format="0" />
<conversion units="kPa relative" storagetype="float" expr="x*0.1333224" format="0.000" />
<conversion units="inHg relative" storagetype="float" expr="x*0.03937" format="0.00" />

EDIT: I see you logged it above - I've had a look, you're logging the raw value which is mmHG. When I convert to PSI, looks right.
