The scaling for the data stored in the ECU to human readable units of measure is stored in the map description area of the rom. Not sure if that is what you're shooting for or not.
RPM is stored as 32bit float directly as RPM, no scaling necessary.
edit: or what tea cups wrote. Or just look at the value conversions. Or pop open the hex editor in Ecuedit and turn it to either "hex" or "float" view. If you click on a map, then hit CTRL-H it will take you right to the map.
