[DML] Re: More on idle speeds

["content22207" <brobertson@xxxxxxxxxxxx>]

I think Dani may be familiar with larger displacement engines, which
do indeed idle around 500-600 RPM. A little engine like the PRV really
struggles that low. But since displacement is so much smaller, you
probably come out ahead in fuel consumption while idling.

Note that DMC lowered B28F idle spec from 950 RPM (I remembered it
incorrectly as 900 in my last post) to 750 RPM. I'm assuming they did
that for emissions -- no smog pump or EGR, standard on B28F.
