So on the MAF tables, theres 4 tables. Does each table correspond to a specific rpm range or something else. Just curious. Thanks.

No, each table corresponds to the Hertz rating that the MAF sensor produces as the air flows through the sensor. The PCM reads that Hertz rating and uses the corresponding g/sec airflow amount that is in the tables.

 

Do a search on MAF and you will find some good info.
