Is there anybody willing to give up the address of CLALM and location of B_error for ME7.5 (518AK). Or even just a simpler explanation of this process. thanks in advance  

I think the address of CLALM should be 0x1C4CF in 518AK, if I did my math right.

mbox:
1b9e2 - KFMLDMN threshold for B_minflr diagnosis HFM/HLM change entire map to 0
10d69 - CWBGMSZS change from 2 to 0
1819c - CDEHFM maf code word change from 1 to 0
18802 - CWDHFM maf code word  change from 0 to 1
and finally, the one map you can change alone to simply remove the illusive p0102 fault and sensor error limp but will not have cruise and esp without the other 4 changes...
10716 - CLALM maf voltage signal error class change from 3 to 1

Round of applause for this guy. I was never able to pull this off with just codewords and maps. I had to do an assembly hack

Actually for ME7.1 you have to do more than one

I will test this on a ko4 or ko4 car asap and report back.

Have you got around to trying this yet on a K04 car? I don't think I'd do it, but curious as to how it works out! I have driven a MAFless 2.7 before, the only diff I could tell was when coming to a stop it seemed to idle hunt a little bit until you were fully stopped. It is super nice to clean up the engine bay, that's for sure.

The only way this will work remotely correctly is if you have setup all the throttle plate calculations properly. If you can do that, you can tune a MAF.

Not even remotely a good reason to go MAFless.

Actually, you are right. Figured out another way. Single byte + map change.

Map change? No.
Single byte code change and error class delete.

Depends on ECU firmware. Different for every file. It is a code change. A patch.

I still fail to see the point unless you add a real MAP and inject the result into load.

I was messing around with this for a little bit tonight
When setting CLALM from 3 to 1 I was still getting p0102, setting it to 0 instead eliminated this.
