I'm not saying you can't. But it's not as simple as dropping the RPM.

Ever play with a carburetor? Ever had a carbureted engine? Remember that choke switch? Same concept.

Basically, raising the RPM is one of the better ways dealing with the unburnt and poorly atomized fuel at startup.

At startup the car runs richer too, to heat up the catalytics faster, etc.

So simply lowering the RPM is not the right approach. Actually addressing fueling, among other tables will be needed.
