Stock MAP sensor -> 3 bar sensor linearization

Postby attz » Mon Jan 02, 2017 9:48 pm

Sup peeps.
As the topic subject says, I got a question about MAP linearization on my 1.9TDI VP37 AFN engine.
I changed the MAP sensor to 3 bar sensor from PD 130/150 engines and compared my ECU map and the PD engine ECU linearization maps, but there's a difference even in y axys(mV).
So my map looks like that:
82mV = 200mbar
989mV = 2600mbar

PD engine map:
82mV = 200mbar
951mV = 3000mbar

The question is - should I just take whole map(edit y axys to 951 and equal it to 3000mbar) from PD? Or should I leave 989 and convert the resulting mbar value?

on that ecu (msa15) you only have to change 2600 to 3000 nothing else..

Well, I have an ECU from AVG engine, so it's EDC15VM+
If I convert my map voltage, I'm getting 989mV = 3120. So should I leave axys 989 and make it 3120 or change axys value to 951=3000?

change the axys as well.. 951=3000
