Not sure if this is relevant, but for bosch files, MLOFS is 200kg/hr but 0 for hitachi files.
200kg/hr is approx 55 g/sec
Yes, last night i am study functionrahmen. Look at the page 262. all about pulsation corrections=1, because SY_turbo=true. Other things is not so difficult at first look: signal voltage from maf go through MLHFM, after that trough GGABT (what this?), after that from this signal MLOF subtracted, then multiplied with KFKHFM, and roughly maf signal is ready.
After that, i compare MLHFM for 2.7tt hitachi maf and 2.7tt bosch maf. Hitachi start readings from near zero g/s, and MLOF=0. Bosch start from about 36 g/s, and MLOF=200. So, i think answer is= (AIRFLOW at aidle/low loads)=(signal from first few cells of MLHFM)-(MLOF). But i dont lok at the MLHFM for bosch NOT rs4 maf, and MLOF for this maf.
But there some lack of understanding about KFKHFM. I think recently, that this map is related to MAF specs. But in functionsrahmen, i read that this map is engine-related (camshaft, VE, and other specs). Next week, my task will be instalation of RS4 maf on 1.8t engine. So, change MLHFM and MLOF on RS4 specs is simple, but what about KFKHFM?? As i understand, entire map from RS4 will totally not work for 1.8t engine??
