EDC16 BMW e46 EGR + Stage1

[JustGav]

Hi,

Ideally I'm not just after a file dump but would rather understand and learn.

Recently rebuilt an e46 320d and now looking at getting rid of the EGR error (I did an EGR and swirlflap delete), not sooo bothered about going to stage 1 but would be nice potentially.

The ECU is BMW 3er E46 320D 150PS 110.3kW Bosch EDC16C31 0281011122 O_55KAC2 361881

I did a read today over OBD which is a partial read (the front section of the file is FF), from what I've read an obd read is sufficient for tuning but I'm not so sure EGR will be within that section.

So my questions are as such
1. Do I need a full read? If so I'll BDM it and pull a full read
2. Which sections require changing
3. How to checksum the file

Sorry for the questions, I originally came from a petrol background (MS42 and VAG 1.8t), so this is a new learning for me.

Thanks

1.No
2.EGR hysteresis and DTCs
3.Tool should correct on writting for that ecu.

1. Thank you :)
2. Okay, will start looking for those location maps
3. I'm using F54 (clone)

I'm nervous of just breaking something (first time and all that)

Here is the partial read

Initial looking around...

I found a file that has EGR off and have done a comparison

E4E72 - Some sort of 1x1 (I guess DTC)
FA068 -> FA075 (14x1)- EGR table.

However when I researched I see people referring to a lot of tables. Does anybody have an XDF, MapPack or even text files that I can use as a starting point please.

Thanks

So, the mapfile looks a little bit more like it (and my addresses were WAY off)

I see E0E2C (16x12) and E1078 (8x16) as being the EGR tables. I will assume these need to be 0'd out, I shall now go look for some DTC bits :)

look here for hysteresis E1F34 and e1f94 ,e1fd4.
