Hello,

I want to know what's really the FACTORY \ STOCK idle speed for a Mini Cooper S 2004, some same say it's 900rpm, 850, 750,700 and some say even as low as 670.

The Bentley manual says 750 rpm, now for you people who got BMW\MINi factory service manual will be okay for you to share what bmw\mini says?

So let's say we have 750rpm as default stock idle speed this cannot be change manually? it's already burned in ECM and will always default to that?

Thank you.... below is a screenshot.

 

June 2006 - Mini training manual - idle speed for all Minis is 750. Official from the factory book. Page 33 of the engine mgmt chapter.

 

What are you looking to do? The factory determined that 750 is ideal, and has built in compensation to make it that value.

 

My 2004 R53 - 750 rpms @ operating temp
(-18 hg - if that matters)
