I have attached the LHiresIII to my 250/1000mm Newt (had to collimate it on guide star ), have put in an APM barlow (2.67x).
I've also done the calib upgrade, but still operated manually (mini XLR plug is missing).
Looks to be a usable setup.

First time calibration (1 times for all):
flat: +
neon: +
ref.star: -
nothing else:++

(used only 1 neon of 0.2 sec)
Will need to define more lines and sum multiple neons, I guess.

For now I was just curious of SNR and usability: But I must learn about neon some more.

Hello Peter,
This is excellent.
Your Lhires looks very good
I supposed you used 600 l/mm grating ?
All the best

Of course, I'm waiting for the spectrum for the database

Thank you Francois, yes it was the 600 grating.
A more correct calibration is in progress, then I will send it.

Okay, noticed I've put in the Ar-Ne lamp (seen tiny Ar lines I could fit to at IR end, after summing 11 exposures of 0.2 secs).
Also learned how to fix bad guesses in CALIB\g600.lst: set the polynom to order 1, then spot the outstanding value in the ISIS logs.
Setting it back to order 2, I've got RMS=0.00747 (hope it's good).
Sent in the result now.
