Yes, what injectors are you running?

I see no wide band data in your one log, are you using an external one? Where is it mounted and has it been verified it is accurate?
Do you have a cam card showing your valve events? How much overlap does this cam have? Large amounts of cam overlap at idle will provide false oxygen sensor readings due to fresh charge air being sucked into the exhaust.
You will likely need to modify your injection timing to keep fuel from being sucked out of the chamber and into the exhaust.
I see AC pressure in your log. Is that your wideband? If so, you need to tell us the type of wideband and the math you are using to calculate your AFR readings.
Keep the channels from the log you posted and add these channels: Wideband, STFT B1 & B2, LTFT B1 & B2, O2 volt B1S1, O2 volt B2S1, and Manifold Air Temp.

-Zero'ing out your injector tip temp table is not the best approach in my opinion. Put that back to whatever stock values were. Just know that after a warm reflash, you may be be rich until your injector tip temp comes down. This is fine, just log tip temp and wait for it to be in a range that is not adding pw. A short drive normally gets this back in range quickly.
Based on the last log you posted and the tune that goes with that log, try taking 15-20% out of your VE table in your idle area or <1600 rpm and <80kPa. Values would be around 1,100-1,200 at 900rpm 60kPa.
Posting logs showing these things along with the corresponding tune is the best approach.
check your injector minimum pulse

What about injector timing? Ive had some sucess with po1 ecms but Im not sure how it works on e38 stuff since the tables are different.
have you gotten this figured out yet? im having the same issue but somehow i think the maf isnt completely failed. i can log maf sensor state and it shows failed but the p0101 dtc isnt setting. i zero'd out the maf curve table and the car wouldnt stay running. it is somehow running off of the maf i feel.
UPDATE*
I WAS WRONG
