Hi, I need help, auto Fiat scudo edc16c34, deleted EGR, through hysteresis, I did not touch the error mask. There are no errors associated with EGR, but after the EGR valve is muffled, error P0104 periodically appears.
During the diagnostics it was found out that the target value of the mass air flow differs from that measured at idle and partial loads. Which map to edit to correct this error?

Thank you, Ferenc, I also know how to remove DTC, but I do not want to do this.
I need a solution to edit the map for a target mass air flow. I can not find the EGR map...

Hi, where did you get that DTC P0104 related to EGR valve?

Hi. The diagnosis shows that the required mass flow should be 280 kg / cycle, and in fact we have 500 kg / cycle, because we have an EGR valve, physically disabled.Due to the difference in the measured and set values, an error occurs.
Which map to change the set value of the mass air flow to the desired value?

Ok, see map "1C555C";"AirCtl_rEGR_MAP";"16x8"

Thank you!
Is this the map?
What are the units of measurement along the axes?

Understood, I applied to the parameters of the map Damos

How can I change the map so that the specified air mass flow is equal to the measured value?
