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

will do, thanks :)

was result with that change?

Quick question - when I got real linearisation of MAP, Could I read real inlet pressure in VagCom? I change more linearisation combinations of 3Bar MAP, but over 2600 I couldnt read. SVBL is also changed. Could You help?

you have to change the diagnostic limiter on your map.. just search on this forum and you will have the answer

Thanks for answer!
