The procedure is trivial: plug in the Lamborghini diagnostic laptop
and select your desired PIS setting... and you are done. Then you
go drive around with the new setting to see if you want to keep it.
This takes a bit more than one trip around the block -- you really
want to go on a nice relaxed drive with all kinds of conditions.
As for technical details...

The default value is 96 hexadecimal = 150 decimal = 5.0 mm. So
every notch is 0.0333 mm. A lower value results in a biting point
at lower rpm (which makes it more harsh/crisp) whereas a higher
value results in a biting point at higher rpm (which makes it more
soft/smooth). The recommendation is to adjust the value in small
steps of no more than 3 notches at a time -- going one at a time
is really what you want... because if you can't feel that, then that
PIS setting isn't gonna make much of a difference to you anyway.

The key when replacing an E-gear clutch is to reset the settings --
that is, make the car learn the "original position when closed" and
the "current position when closed" values for the fresh clutch disk.
Otherwise it will continue to use the settings for the old disk, which
will cause the new disk to wear out really quickly. (If it was even
drivable to begin with -- you should feel this mistake right away.)
Adjusting the PIS setting is separate -- it's really just a way to fine
tune the "match" between your car's clutch and your driving style.
You don't want to over-do the PIS adjustments of course; otherwise
you end up with too much bite (bucking... to the point of stalls), or
too little bite (slip... to the point of no-go), and wear rate will suck.
