DET3+ frequency MAF modification - not modificating

GENERAL
1

Hi!
Have a problem with the frequency MAF signal modification.
Car - BMW 2011 N52B30, custom turbocharger installed.
My N52 has the MSV80 ECU, which is driving by the frequency MAF.

So my task is to modify this signal or to convert frequency MAF to MAP.

The problem is - that the frequency MAF signal is not modified. No changes with the AFR after trying to modify from -120 to +120 on the fuel map.

Analog inputs - MAP, IAT, AEM wideband, TPS.

Have the following settings for the MAF frequency:
I googled and researched that my maf is working between 3000hz to 20000hz.
Selected the nonlinear frequency MAF.
Maybe, there is a mistake in those settings?

Am I right on the point, that my changes in the fuel map even at the idle engine rpm should be applied as on the AFR too? E.G. I change the idle point to +30 and the AFR should change too?

Have an update for that. For MSV80, which is quite complicated with its security, I had to adjust the fuel map accurately, adding fuel percentage not more then 10-12% on each point with neighbour point. And then it worked. But unfortunately my stock injectors are too small so on 0.8 bar of boost they gone, and AFR was 17)
On the idle rpm, you can not adjust afr by DET3, the MSV80 is not using MAF on this stage, it is just validating that he has MAF signal. And so like on low engine RPMs while moving - lower than 2500 RPM - no corrections available.

In case you put and calibrate in main ECU new bigger injectors - you will have no problem with that. I decided to move to Fuel Implant mode.
