Idle ?

I have a mb c-220, 1995
i understated that at normal idle the engine RPM is determined but when the a/c is engaged the idle increase at a higher RPM

what RPM should that be ?
is that determined in the software ?
Would an small air leak alter this ?

is the cpu upgradable ?

Duno, all that is determined when you scan the car with either DAS or XDOS--it all happens automatically.
As I do not have time to search and teach you about your cars rpm---get off the couch and subscribe to MB WIS and learn yourself.
