Hi guys,
I am trying to do an EGR OFF on a EDC16CP34 Audi 2.7 and i saw online that one the simpler methods to do it is by zeroing the hysteresis maps, if the egr valve is functional.
In my case everything works properly except a clogged cooler. I also have a healthy DPF and want to keep it that way.
I think I've found the maps at the following addresses:
• 1C66D6 "Bosch 16" (8x1)
• 1C66F8 "Bosch 16" (8x1)
• 1C673C "Bosch 16" (8x1)
• 18B0E6 "Bosch 16" (8x1)
• 18B108 "Bosch 16" (8x1)
• 18B14C "Bosch 16" (8x1)
But I am not sure which of them or how many of them should I modify: 2, 3, 4 or all of them.
On another forum I got an edited file from an helpful user. In his version, only one map is zeroed out, along with changes to other addresses that I don't fully understand. It may very well be a viable solution but because i didn't got to explain there my need to have the DPF still regenerating and also to keep the valve connected, I am not sure if he took that into consideration.
I have attached here both files.
It would be very helpful if someone could give me a good piece of advice.
Thanks!
