It's not uncommon for there to be slightl fluctuations of rpm while at idle. The ECU is continuously adjusting the ignition timing and air bypass to counteract variation in engine load. For instance. The AC compressor will cycle in and out. This will cause slight changes in idle while the ECU compensates of the load imposed.
Even the wife's year old Ford Kuga has a slightly variable idle.

Thanks for that,i think would buy a elm237 and some torque pro app for live data.
......the first line after 0 means 500 rpm ??

The idle speed can be calibrated ?,I mean if i want 800 rpm at idle with engine hot can be done?
....at 700 rpm are some vibrations ...
is a screw on throttle body if i screwed rpm will rise but not for not for long time i think ECU adjust rpm to a default data....

You could probably have the idle speed "tweeked" as part as an engine remap. However this seems to be a lot of expense, for little gain. The ECU will alter the ignition timing to maintain the correct idle speed. So by artificially opening the throttle, the ECU simply retards to ignition to compensate. This could lead to burned valves and an overheated cat. LR chose the idle for a reason. I expect it helps keep emission lower, than a high idle speed would give.
Yours is running at 750 to 800 Rpm, which is spot on factory specs.
