Options for data type and stock units?

In TunerPro there are options for Data Type and Stock units for all values in the ADX. It helps identify for data tracing also available in XDF.
There's a few I am confused on?

1. Fuel Trim
2. Fuel Trim Course (should be coarse I think)
3. Fuel Trim Long
4. Fuel Trim Short

Some of these may be a ford or other then GM thing. I think INT would be Fuel Trim short and BLM would be Fuel Trim long... not sure about fuel trim or fuel trim coarse.

Also a space for data type? Are there just counts? INT and BLM are? Not inches or gallons or volts etc...

Like for Tachometer, Data Type would be Engine Speed and Stock Unit would be Revolutions Revolutions Per Minute.

EDIT: I changed the name of the thread so it could continue for other Data Type and Stock Units.
