Engine start warmup times

Engine start warmup times
I have owned this car for a year now and since the beginning I have thought the high idle on initial startup was excessive.
Regardless of ambient temp the car stays at high idle for what seems like an eternity on initial startup or if the car sits for an hour. No other vehicles I have owned stay at high idle this long unless it’s really cold outside and the idle times are much shorter in the summer, but the Jaguar doesn’t seem to care about the ambient temp.
Is this normal or something that can be adjusted in the programming?
The ambient temp was 86 F for this startup.

I am not talking about the initial vroom at startup, I am measuring the sustained high idle of about 1200 RPM’s before it drops back to normal RPM.

That's what I'm talking about, too. If I remember(!), I'll time mine next time I start it. I've never considered mine to stay at high revs for an excessive time, though.

Mine idles up pretty high for quite a long time as well. I think it is normal. Would not worry about it. It lasts about the same as my 997 TT and Cayenne S, so not worried. Gets that oil pumping through the engine before you pull off.
A minute is not very long....."That's what she said" ...

Mine did 33 seconds start to idle this Saturday at 5 AM stone cold - not started for 6 days. Garage ambient temp was 74, outside 59.
Restest - same day, Saturday late evening (9P) after sitting all day for detailing inside with doors open until 6 PM when sun hit rear of car during detail - cold start at 76 degrees ambient, outside at 79 with high of 83 for the day, to idle - 31 seconds.
Rougly the same as all our cars from cold start inside insulated garage to idle. We never put into gear until steady low idle.
