L98 engine maf sensor issue

[BasselAlawar]

Hello guys,

I am facing a very critical issue with my E38 ecu / l98 engine, MAF 213-4222

When I connect the MAF, starting the engine is not smooth, and at first the ecu popped error code P0102?MAF low frequency MAF input. We checked the wiring, and it doesn't seem we have issues. Tried another MAF, same issue. We are also having 50% trims when MAF is connected, and the forecasted MAF reading is double the MAF reading. We tried to check the HP tuners MAF frequencies but had no success. Can someone please help with the issue?

Need tune, log and a lot more details on what you are working on.
