Hey guys like stated above I have an E38 and I repined the harness to run a GENIII MAF since getting a CIA for a van MAF seemed like impossible. I repined and the scanner is seeing NO airflow and of course No frequency output. In HP Tuners I changed the MAF calibration g/s to frequency to match or closely resemble what this MAF does on a GENIII engine. I checked the MAF before and Aft on a Gen III and also verified in my scanner that frequency and flow was right. I'm hoping someone can help out on this one as I need to get this swap done and to the owner. Thanks
