high idle at start even when warm

As the title says every time I start the beast it revs to 1500 rpms before settling to its normal 800 or so. not temp or weather dependent. I'm guessing this is normal? Can I change this to maybe peak at 1000rpms? seems a waist when running errands. thanks

No it kind of done by the ecu when started. Once it gets the right inputs it will dial the idle back. In the summer it should only do it on the first start up. On cold days when you may be running short trips it may do it more often.

Sounds like mine but it actually settles in rather quick.

If it is doing it for a long time the question becomes what thermostat do you have. Is the air inlet temp sensor hooked up. The ecu gets signals from the temp sensor for water and air along with others and it they get warm it should start to drop the idle.

yes about 3 sec before it is down to normal. Going to see if the BMW does this too. Don't remember my SHO doing this. Bike has a manual choke so that doesn't help.
