What does MAF calibration affects?

Dear HPA team,

greeting to all of you...

Does MAF calibration affects AFR in part throttle and fuel consumption?!!!

Actually I've asked this question in yesterday's YouTube live video, but unfortunately I didn't watch it when this question was answered! :(

Thanks and looking for your answers :) ....

The MAF calibration affects the accuracy of the fuel delivery everywhere. idle, part throttle, and WOT. The MAF sensor tells the ECU what mass of air is entering the engine which it needs to know in order to calculate what pulse width to send to the injectors in order to get a specific air fuel ratio.
