Okay, I'll take a deeper look.

Are you sure the BAM is running @4bar FP? I've read 3bar so often in BAM context, so I didn't even think about that one.

I've started comparing BAM and AUQ stock files a while ago. I'll go on with that now. Thanks!

Oh and to be specific, atm its k04-022 (no egt probe), BAM injectors and 3bar FPR

i started by comparing stock auq file with the file that was on the car, because i knew how the car behaved. now for the k04 install i compared both with bam values so far.
so in conclusion to our last posts, i will start over with the auq base file and put in the necesarry bam values.
I've attached my compare file, in case you'd like to check it and tell me if i'm missing something.

I'd like to do the same with bfv file, but to be honest I'm to lazy to make a proper xdf

thanks so far

Thats what I did, I've read S4Wiki step by step, checked in the FR to get a understanding what var is for what. Pasted the tables side by side into excel and let excel mark the differences in the tables.
So far I compared IRL, IOP, LDRXN, KFLDRXO, KFLDHBN, KRKTE, KFMLDMX, KFLBTS, MLHFM, MLMAX and a few more.

what i don't really get into my head is the relation between iop and irl. 

Why does the BAM not use BTS? The values I see seem normal to me, 1.01 at low rpm and load and going to 0.8 up top.

inverse like square and root for example?

those are the bts values in the TT bam file i have (8N0906018BP)

No, not really inverse that way either.

"mathematical inverse" isn't it at all. More like "reverse" process, as in one is torque to load and the other is load to torque.

ah okay. now I kinda get it. So the ecu is using it as some kind of backup calculation right?



when the lowest value is used for target afr and bts is 1.0 all the way and LAMFA is 0.95 up top the target afr will be 0.95 without KR activated, right? How does the KR apply? Do I have to expect the engine to knock or is it some kind of backup in case it starts knocking due to high temps/boost/compression/fuel quality? I guess a retail software wont run at KR limit?

I want to understand what is my best way to approach my AFR tuning. I guess I have to get this right first before playing with torque/boost etc pp

So in my opinion its not that smart to use KR for fueling in open loop, because i dont want my engine to knock, right?
And I guess I'm driving in closed loop most of the time any way so why use KR for fueling here? Maybe I'm not really understanding how its applied but as I see it, it would be a good approach to use LAMFA in closed and BTS in open loop??

Oh okay thanks.
