base idle is suppose to be set to 880 +/- 50 rpm
as described in the archives :p, to set base idle:
engine warm, proper operation, no intake leaks, all electrical & AC off, good air filter
disconnect throttle switch connector from wiring harness
on harness side of connector insert pins/wires/etc and ground all three pins in the connector together
adjust base idle, adjusting screw is located between valve cover and fuel rail just above the "M" in the "BMW M Power" lettering on the valve cover
technically you would do a throttle body air screw synch and set the CO afterward, then recheck the base idle again
