Hanging RPMs Between Shifts?

Zasquatch · 01-10-2011, 07:14 AM

Occasionally in between shifts - i.e, when clutch is depressed and foot is off the gas - the RPMs will hang for a minute before dropping. Under high boost conditions (~ 15-16 psi lately in 30 degree ambient temp with the V5 on my otherwise stock car) the RPMs occasionally increase a small amount before dropping.

Anyone have insight or experience with this?

Yes, I am experiencing this and I suppose it is a feature from BMW in order to avoid a big RPM drop between shifts. I noticed it is more pronounced when lifting the foot off the throttle fast, and less pronounced when lifting it more slowly.

Cool, good to know it's not out of the ordinary.
