bgd73 Posted June 21, 2006 Share Posted June 21, 2006 Could I use a mass air flow setup from a nissan sentra with a 2.2 L or any car? The size of the oem for spfi is small on the subaru and know it would take much more, like an old carbed one. I read briefly on signals sent to ecu, and don't know about nissan side of things. Japanese car with similar year surprised me with many "alikes". Anybody done this? Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted June 22, 2006 Share Posted June 22, 2006 MAF sensors have a specific transfer function associated with their response to airflow. So if you wanted to swap MAF sensors, you'd want to use a MAF sensor with the same transfer function as the one you're replacing it with.....or match whatever the ECU is meant for However, if you are using different engine management...stand alone, or piggy back that controls fueling, you should be able to use any standard MAF sensor.....it'll just require tuning to get things right.

bgd73 Posted June 22, 2006 Author Share Posted June 22, 2006 hey thanks. My bros nissan sentra is not a planned thought, the car just happens to be available for gadgets. there is resistance measured across a hotwire with some intense math. The volume increased on a sube ea82 would be slower than the oem maf, presumably leaning conditions a possiblity? I am not sure how nissan sensors work , and the element of time to consider with the ecu clock. I heard often with the car brains: "they're basically all the same, attempting a standard". thanks for help, I really want to give the spfi a bit more than it isn't getting, I am in the 30's to 40's mpg and could afford a little less.
