ZTAudi  EDC16CP34 4BAR MAP convertion help needed
It is Audi A4 B7 2.7 tdi V6 diesel engine swapped in A4 B5. I need to make ECU MAP sensor linearization for 4bar MAP sensor. Sensor is 0281006059. Anyone can help? I tried to do it my self, but ECU shows 680 mbar at idle when it should be around 1000 mbar.

RE: EDC16CP34 4BAR MAP convertion help needed
Yes that I know but changing it for that sensor results in measuring the pressure wrong.
I put voltage from 401 5000 to 498mV 4496mV using factor 4,887585532747
and changed measuring range from 201mbar 3231mbar to 499mbar 4000mbar

and ECU shows 680mbar when ignition on and engine on idle too. Should be around 1000mbar, so the measuring is still wrong.
