Hi guys.

Looking for some advice.
I would like to close EGR using 4 maps.
But I'm not sure which one should I use.
I made two reads, obd + bdm, but they are different at the same addresses , some maps are swapped.
Could you please tell me which one is correct and what is general approach to it?

If you have bdm read, try set 0 in: 2 and 4 hyst map.
In bdm read I see 2 blocks. Set 2 and 4 hyst map to 0 in both blocks.

Then EGR should be closed al the time?

Tak jest ;)

Thanks, dziękuję.
Why only 2 maps per block, not all 4?
I think I sow somwhere all 4 maps with zeros.
