M50B30 fuel problem

[plamen83]

Hello i have a problem with my e46 330 m50 vanos engine.
On steady 4500 5000 or 5500 with no load the afr go below 10.
There no fuel corrections and changes in map,ve or tps and fuel ms go from 1.5ms to 2.5 or 3ms.
Here a log and my basemap file.
Any ideas?

Well,
there is no M50B30 engine on the this Planet....

What is your engine really ? M54B30 double vanos ?
If you have Vanos engine and your VVT is not set, you will end with very strange looking engine.
Do you call it tuned engine ? Its terrible what i see.

Or do you have some "Clone" engine and it is turbocharged or what ?

Sorry its m50b25 3ltr stroker
M52 crank pulley.
The engine is 8.5 cr with holset hx35
The car run on boost fine without a problem.
This happened only in this rpm range and between 4500-5500and 70-100Kpa.
With vanos on and off its made it.
Here the map

Your car is not tuned well. Just look into the VE and IGN maps and you will know. Only issue is bad tune, nothing else.
