Detailed description of parameters

[the1andonly]

There is an help window on RHS .sometimes this is empty or less than helpful.
The names of the parameters are not always obvious what they mean.
IS there an additional file some where that gives more explicit descriptions? (either within Multiecuscan or elsewhere.)
Specificaly i am looklng at Throttle
I have looked at the translation Language files English.txt and English.dat and in the .dat found over 20 for with none being the precise name in my parameter list (Ducato X290)
Throttle position
Throttle position (target)
Throttle valve opening
do these refer to the throttle body or the throttle pedal (accelerator).
There is an extreamly good example of Detailed description of parameters in a post for creating a translation file, i just need to translate Fiat into Inglish.
Any assistance would be appreciated.

often such info can be found in service manuals for car.

Unfortunately no Service manuals for twin EGR x290 Ducato available.
The precise meaning used within Muliecuscan is what i'm after

somehow I doubt it. maybe it's not available in free form but dealer definitely has such info for repairs.
