It's ok, i have found MS45 A2L and now i work on it.

I attached two a2l files for older versions of MS45.0/1 maybe it helps

Please find attached Pazi's v0.2 definitions with small corrections (for example ignition angle calculation for all but RON98 maps) and additions for 44560BO00S0 MS45.0 software (partial read which I was working on also attached - it is ZUSB 7561488 for EURO X3 E83 3.0iA).
Additions based on posts by Johny_B, Lambda1, diablospeed and A2Ls for other MS45 revisions.
I hope I got axis right

Could anyone help with pop and bangs modification for those ECUs? At least posting maps with addresses for any "current" software revision (MS45.0 prefered )...

Please do pull request in github if you have additions or fix to definition. It's easiest way to include those.

Done

Hey guys, i'm working on 4570LJ10, and have found the Ignition angle maps for RON 98 and 91, pretty simple. However i'm trying to identify the post cat o2 diagnosis config switch. Does anyone have a damos or a2l file for this version? Or any pointers of how to trace config switches in IDA Pro, any and all help would be appreciated.

Easiest way to find is compare in wols. One binary with damos file and on the other side your ecu file. The ecu files gt updated with small changes, so the position of config switches usually doesn´t change much.

I found the config switches from 0x44BEA --> 0x44CCA on 4570LJ10

Shoutout to diablo, I found the o2 config switches for versions 4570LJ10 and 4570LO00, they are 0x44C47 and 0x4499D respectively. I'm working on finding lc_inh_sa_man_deac now, i'll hopefully have those soon

Second a2l is not ms45.0. Its ms45.1...

I know, that's why I wrote both versions

456 -> 45.0
457 -> 45.1

Yes I know but... Rev limiter in 456 is 1x9 and its like in ms45.0. In ms45.1 is single valut but everything other in this 456 its like ms45.1 and they are a torque map from ms45.1. This map in ms45.0 dont egsist. And a lot of simlar situation. Even if it is ms45.0 its completely different from all ms45.0 what i read from e60 x3 or z4 so unfortunately it won't be useful for discovering the "normal" ms45.0...

edit.
Now I analizing ms45.1 and rev limiter are 9x1 so for me this 456 is normal ms45.1

Hey everyone, quick question.

So I had a friend who has codes P0430 and P0420, as in failing cats. It's MS45, version 4570LL00. I found the config switch for lc_inh_cat_diag_man_deac at 44C69, set it to one, and flashed it. He says that the codes came back, so I'm wondering about the validity of using this switch for all vehicles. Its a 330i ZHP by the way. I managed to find c_conf_cat and other config switches listed on the wiki for this version, but i'm wondering if anyone could shed some light on to why this config switch wouldn't have gotten rid of his codes?

Thanks!
